1. Scope and Applicability

This PCR starts with actual full supplied annealed uncoated soda-lime float stock sheets and covers fabrication, washing/drying, electric roller-furnace thermal treatment and air quenching through first quality release of flat unframed monolithic thermally toughened safety glass. Complete actual size cutting, edge preparation and holes before toughening. Include heat soak only when truly specified and performed; a generic safety name cannot establish the terminal or route. Stock-sheet manufacture and non-safety edgeworked-sheet methodology cannot replace this thermal conversion. Laminated fragment retention is different from monolithic toughening; heat strengthening is not safety glass. This specific product and manufacturing need is independent of the classification leaf and is a narrower methodological subset of CPC37115. pilkington-toughened-glass; gpd-tempering-control-2023; landglass-wash-dry-2020

The primary sources below form a transparent technical synthesis without asserting one order, factory or SKU. Actual provider identity and future site quantities must be supplied during data production. Do not transfer marketing performance, schematic quality curves, typical furnace temperatures or a manufacturer conformity claim as dataset defaults. Storage, packing and handling after first release retain separate physical/service ledgers and cohort attribution without creating new production.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
`reference_mass`	reference product	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Use 1 kg of first-released net glass with dry surfaces. Record each pane or homogeneous measured mass lot on a calibrated scale with packaging tare; no assumed per-pane mass, nominal thickness-density conversion, strength or service life.
`raw_units`	raw inventory	actual measured property	recorded unit	Preserve raw meter units. Convert kWh to MJ with factor 3.6 only for electricity. Integrate actual rates once; do not multiply integrated liquid/gas volume by time. Volume-to-mass requires independent substance-specific density at measured temperature/pressure/composition; never substitute water density for oil. Counts/area use actual weighed article/pane configuration, not a secondary coefficient.
`single_denominator`	all inventory rows	actual row property	row unit per kg	Collect unnormalized raw totals; convert, reconcile stocks/cohort inherited burdens and allocate first, then apply normalize_exchange once. Cards and protocol aggregation refer to that result; no second division. Q=0 retains real burdens and yields no unit result.

5. System Boundary

The following rules apply together. Retain every actual operation and attributable burden; zero output or failure is not a reason to delete it.

rule_id	Applies to	Rule	source_ids
`boundary_route`	all manufacturing	Start at receipt of full annealed uncoated soda-lime float stock sheets. Include stock handling; actual cutting and edge grinding; required holes before heat treatment; washing and drying; electric roller-furnace heating; forced-air quench; inspection and destructive sampling; any specified heat soak and rejection; first release; and actual downstream storage/packing/handling service. This is a technical synthesis across primary sources, not a claim of one SKU or factory. No furnace temperature, density, strength, yield, energy, lifetime or certification default is set.	`pilkington-toughened-glass`; `gpd-tempering-control-2023`; `landglass-wash-dry-2020`; `glaston-fc-flat-tempering`; `bavelloni-ve-edgers`
`boundary_upstream`	all purchased inputs	Attach actual compatible upstream burdens to full supplied sheets and each utility, supplied formulation, tooling and packaging input. Do not reproduce melting, tin-bath forming or annealing inside this conversion boundary. Do not replace conversion with purchased safety-glass packaging. Same-category external safety glass is an explicitly separate burden-bearing resale/service input and is excluded from newly manufactured Q.	`pilkington-toughened-glass`
`boundary_release`	first_release and handling	Q is the sum of uniquely identified panes passing first required release in the reporting cohort, measured as net glass mass with dry surfaces. Destructive samples, pre-release rejects and opening already-released FG are not Q. New closing FG has already crossed Q and must not be added as another manufacturing output. Track the physically distinct FG service ledger and cancel internal Q transfers. Deliveries, returns, reinspection and repairs never create new Q. Keep original release and delivery references; reverse only the original delivery-ledger assignment before reassigning returned glass, never the original first release or its manufacturing burden. Newly released closing FG retains its complete manufacturing burden inside Q. Observed incremental post-release services follow the original release cohort and declared service interval.	`pilkington-toughened-glass`; `gpd-tempering-control-2023`
`boundary_complete`	every actual exchange	Include failed runs, zero-output periods, warmup/cooldown, idle, start/stop, cleaning, test breakage, rework, utilities, captured waste, leaks and emissions. Unlisted actual inputs or exports require additional chemically/physically specific atomic rows with actual identities, properties, conditions and destinations; no hidden other, zero or lumped balance category is allowed. Absent exchanges require actual route evidence. Retain monitored unknowns and uncertainty; do not force balance closure.	`gpd-tempering-control-2023`; `landglass-wash-dry-2020`
`boundary_fluid`	WIP and non-WIP stocks	Maintain quantities and a separate inherited vector for every exchange in opening/closing glass WIP, raw stocks, installed lubricants, wash tanks, recirculating liquids and other equipment charges. A stored litre or kilogram is distinct from embodied energy or each upstream exchange. Assign only attributable use/losses/removal, carry retained PRE-release or unused-stock burdens forward and cancel internal transfers. Newly released FG is already inside Q; its complete manufacturing vector is carried for traceability without reducing manufacturing A_j. Equipment fluids are not WIP panes. For any actual external steam/heat or condensate return, add separate atomic supply and Product-return flows with actual mass, temperature, pressure, phase and enthalpy and the supplier water/energy convention; this electric air-quench route does not presume a boiler.	`gpd-tempering-control-2023`; `landglass-wash-dry-2020`
`boundary_exclusions`	scope and terminal	Exclude heat-strengthened-only panes, chemical strengthening, lamination, coated/enamelled/printed glass manufacture, bending, mirror silvering, insulating-unit assembly, framing, installation and use/end-of-life from this specific route. Fully toughened monolithic glass is not automatically suitable for post-breakage retention or a laminated balustrade. Actual conformity and performance are manufacturer/test records, not inferred from a safety label. A materially different terminal or route needs its own methodology review.	`pilkington-toughened-glass`; `gpd-tempering-control-2023`

Boundary Abstraction

Field	Value
declared_starting_condition	Full supplied annealed uncoated soda-lime float stock sheets
starting_condition_role	Burden-bearing supplier product entering conversion; not purchased-safety-product packing
product_classification_scope	CPC 3.0:37115 narrower flat monolithic thermal-toughening subset
recursive_input_rule	Separate external same-category safety glass as burden-bearing resale/service input outside new Q; cancel matched internal prepared panes
upstream_dataset_requirement	Actual stock-sheet provider through annealed stock production; match state technology geography for each flow; retain row-level electricity voltage/mix limits
disclosure	Declare start/terminal, recipe/testing, cohorts, opening/closing inherited vectors, equipment fluids, species/destinations, packaging and service attribution

6. Process Inventory Structure

All cards share the first-release reference Q. Each card is one actual physical or chemical exchange; its amount only references normalize_exchange and never divides by Q again here. Absence of a conditional exchange requires actual configuration evidence. Additional real material, fuel, maintenance formulation or emission requires its own named atomic card rather than a collection. UUIDs establish identity only; unresolved auxiliary flows remain concrete single exchanges. Cancel internal prepared transfers and the first-release transfer into the service ledger on consolidation. Blower air is a heat-exchange service using actual ambient air; its electricity is included without inventing a purchased compressed-air flow. Retain air throughput and inlet/outlet temperature/humidity in operating records; unchanged nitrogen, oxygen and other individual pass-through species cancel on both sides. Only independently established net species changes enter the actual receiving-medium inventory.

Product flows

Float glass and surface ground or polished glass, in sheets (`raw_sheet`)

Receive uncoated annealed soda-lime float stock sheets, not already toughened or laminated. This generic manufactured sheet Product at-plant identity supplies Mass only; no CAS, grade, thickness, geographic, density or performance constraint is supplied. Qualify the actual annealed uncoated float subset and supplier burden through annealing and stock-sheet production. The name also admits surface-polished sheets; that does not authorize substitution of an already fabricated pane or reuse of a generic provider. Record full sheet purchases once and actual cut losses.

Alternating current (`preparation_electricity`)

Meter the actual operation, extraction, pumps, drying, drives and attributable auxiliary electricity. UUID is CN grid-average consumption mix delivered to users below 1 kV, Product flow, AC synonym; native reference property is Net calorific value, not Mass. Use only for that matched supply; other geography, voltage, self-generation or supplier mix needs its own identity/provider and explicit transformer losses. The engineering route is not restricted to China. Do not purchase internal blower air or a second electricity supply for the same kWh. Preserve start/stop, idle, unsuccessful loads, cleaning and rework.

Process Water (`wash_water`)

Treated industrial process-water Product only: native synonyms include service, utility, reclaimed and recirculating process water, but the exchange is actual external treated-water makeup. No purity or geography is fixed by the native record. Match actual treatment, rinse quality, supplier and state. Internal circulation is not new purchase or natural-resource abstraction. Separately add actual raw-water abstraction/treatment and its electricity if done onsite.

Light petroleum glass-cutting fluid (`cutting_fluid`)

Conditional only if this specific supplied light-petroleum formulation is used for scoring. Record the whole purchased formulation once with SDS, supplier grade and independently measured density at recorded temperature if volumetric. Constituent assays and carrier fractions are subledgers, not extra purchases. This is not a universal cutting-fluid recipe; different actual oil or an oil-free scorer needs its own atomic exchange or documented absence. Identify actual evaporating chemical species individually from SDS and measurement; a total VOC reading is not a named chemical mass.

Aqueous glass-washer detergent formulation (`washing_detergent`)

Conditional whole supplied aqueous detergent when actually used and compatible with the washer and uncoated substrate. Supplier formulation and carrier-water assay remain explicit; do not add that water as purchased wash_water again. Site mixing requires each actual purchased ingredient, mixing energy and losses in separate rows. A water-only washer does not acquire this detergent by assumption.

Diamond-bonded glass-edging wheel (`diamond_wheel`)

One supplied diamond-bonded wheel article with actual bond, dimensions and wear/replacement records; allocate its embodied burden over measured use without inventing service life. This does not include loose diamond, crystalline silica or an entire machine. The equipment source also offers bakelite/felt/cerium polishing configurations; they are adjacent alternatives, not ingredients of this simple ground-edge route. If actually used, create each real wheel, felt or polishing formulation exchange separately.

Mineral machine lubricating oil (`machine_oil`)

Conditional actual non-WIP machine oil charge and makeup; distinguish initial equipment fill, retained circulating stock, replacement and leakage. Carry a separate per-exchange historical burden vector for opening/closing installed fluid and spent removal; a fill is not all consumed merely because purchased. Do not classify equipment oil as glass WIP. A different lubricant, grease, refrigerant or coolant requires a separate chemically specific row, not this oil label.

Glass-washing aqueous effluent (`wash_effluent`)

One actual wastewater stream to an identified offsite treatment receiver; sample flow and species/solids. Measured integrated volume is not multiplied by time again. COD is an indicator and not a chemical mass. If treated onsite, add every actual treatment reagent, electricity, sludge and individual species discharge to its real receiving medium; do not retain this offsite stream as an additional discharge.

Only incremental H2O evaporated from washed panes or the water system to air, unspecified subcompartment; native CAS 7732-18-5 and Elementary emission-to-air identity with Mass reference. Native synonyms contain broad water/isotopic terms but do not justify heavy/tritiated water, liquid effluent or steam supply. Prefer measured receiver subcompartment if known. Measure inlet/outlet humidity and dry-air flow or independent water balance with measured liquid and sludge stores. Ambient water pass-through is not new process evaporation.

Safety glass (`first_release`)

Quantitative reference: newly manufactured unframed flat uncoated monolithic thermally toughened soda-lime glass that passes its first required quality release. Native Product identity is generic Safety glass, finished manufactured product, production mix at plant; no CAS, geographic, thickness, specific thermal route, certification, fragmentation or strength limit is supplied. Thus qualify the thermal route and actual test/specification independently. This identity is not evidence that heat-strengthened, laminated or chemically strengthened glass is interchangeable. Q counts actual net dry-surface glass mass once after all required tests including heat soak only when specified, excluding packaging and destructive samples. Closing FG already includes any newly released panes.

Fractured thermally processed soda-lime glass reject (`quench_reject`)

Weigh furnace, quench, handling-before-release failures and destructive test fragments separately by origin within the same segregated physical glass waste, retaining all heat and input burden. Never assign only successful-load electricity or count a sacrificed specimen in Q.

Safety glass (`released_received`)

Previously first-released glass physically received into or dispatched from storage/packing, with cohort, original release, original delivery and return link. Same generic finished manufactured Safety glass Product at-plant identity and Mass restrictions as first_release; only actual qualified flat uncoated monolithic thermally toughened soda-lime panes are represented. This is a physical service transfer, not new production Q. Cancel internal receipt against manufacturing transfer; keep gross dispatch, returns, opening/closing FG, repairs, breakage and retained water in the physical service ledger, and reverse only the original delivery-ledger burden assignment before reassignment; never reverse or re-charge manufacture already assigned at first release.

Broken previously released thermally toughened soda-lime glass (`fg_breakage`)

Actual post-release storage/packing/return breakage with original cohort mass and inherited historical burdens; it is not another pre-Q failure or negative new production. Physical FG loss and the assigned service burden remain visible. Actual cleaning, repacking or rack maintenance must record changed water/material mass and incremental energy and losses; reverse only original delivery-ledger attribution when reassigning a return. Such service is not restoration of fractured glass or a failed safety test into a compliant pane. Broken glass remains waste; replacement panes require their own complete manufacture and unique first release, with no second Q for the original pane. Re-melting/re-manufacture is outside this conversion route and requires separate methodology. Reinspection never resets Q.

7. Allocation and Co-product Handling

The sequence below applies only to attributional multifunctional processes. Industrial manufacturing documents do not by themselves establish LCA allocation rules.

rule_id	Applies to	Rule	source_ids
`allocation_subdivide`	attributional manufacturing and services	Use attributional modelling only. Identify exclusive sheet, machine, batch and service records first; subdivide or virtually subdivide wherever quantitative technical relationships can isolate an exchange. Keep manufacturing and FG services separate and allocate each to the relevant release cohort. Do not choose arbitrarily between physical and economic allocation.	`ilcd-attributional-2010`
`allocation_causality`	residual shared exchanges	For each exchange remaining shared, identify and document the determining physical causal relationship. Do not apply one mass ratio to every flow. Different thickness, loading, heating recipe and quench intensity require actual measurements/models; area, time or mass are not interchangeable automatic keys. For shared rack/storage/transport services demonstrate the actual limiting capacity and duration/distance. Preserve failed-load and idle burdens and document any distortion.	`ilcd-attributional-2010`; `gpd-tempering-control-2023`
`allocation_residual`	genuinely inseparable residual multifunctionality	Only for genuinely residual shared flows after the preceding steps, use contemporaneous market values of actual co-functions in their real condition and amounts at the same common-process exit/entry gate. Strip downstream-only finishing, transport, packaging and margin from remote prices. If the correct value cannot be established retain a review hold and quantify sensitivity; do not invent a fixed percentage. This concerns multifunctional processes, not QFD comparison of multifunctional consumer products.	`ilcd-attributional-2010`
`allocation_waste`	rejects returns and packaging	Waste and internal recirculation are not automatic co-products, negative production or avoided-production credits. Establish actual product/waste status, ownership, treatment and burden transfer for external cullet and retired packaging. Preserve original burdens and actual incremental repair/service loads; never erase failure burdens or count returning racks as new purchases.	`ilcd-attributional-2010`
asset_manufacture_conservation	existing capital/reusable manufacture attribution	Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

8. Foreground Data Collection, Calculation, and Quality Rules

The protocol aggregation_rule cell declares the final reporting basis only and performs no calculation; the collection method retains unnormalized totals and references the same sole calculation below. Collect raw records before division by the reference quantity. Keep physical observations, historical exchange burdens, allocation and final unit results separately. Manufacturing attribution ends at first release for all Q; post-release service observations retain the original cohort Q and observed interval, including unshipped FG. Stored manufacturing history is not a second service input or a deduction from already released production. Apply each complete rule with its context; do not extract a formula while omitting adjacent conditions.

Data Collection Protocols

For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
`convert_raw`	all inventory rows	Convert each raw reading to its declared row unit before attribution. Electricity MJ = actual kWh * 3.6. True rates require integration over the measured interval; cumulative readings use differences once. Use independently measured density/state for actual liquid/gas volume and measured article configuration for count/area conversions. Preserve original readings and units.	raw observations; unit factors; measured density and state; measured article configuration	converted raw exchange totals	`gpd-tempering-control-2023`
`attribute_raw`	all inventory rows	For each exchange j and its identified cohort ledger, use A_j = B_open_j + converted_period_j + B_external_returns_j - B_close_j - B_transferred_elsewhere_j only for attributable stock/burden reconciliation, then apply documented subdivision or residual exchange-specific allocation. Manufacturing B terms cover unused raw materials, non-WIP equipment charges and PRE-release WIP only. Assign complete manufacturing burdens to all Q at first release, including its newly released closing FG; never subtract that FG manufacturing vector or re-charge opening/returned FG manufacture. Carry it separately for traceability. Post-release service A_j contains only actual incremental service exchanges and their own retained/used stock vectors, matched to the ORIGINAL first-release cohort Q including its unshipped FG over a declared observed service interval; no forecast service or division by unrelated current-period Q. If original Q or the service attribution is unknown, retain raw records without a unit result pending review. Original delivery reversals move historical burdens between delivery/cohort ledgers only and do not reverse first release or manufacturing Q. For physical directional transfer/dispatch/return/waste rows, retain the actual gross movement assigned to the cohort as A_j; do not apply an inherited manufacturing stock correction to the physical movement. B terms are vectors of that same exchange, not scalar glass stocks. Count each purchase once and cancel internal transfers; reconcile physical amounts and environmental burdens separately. Corrections reference original records.	converted raw totals; exchange-specific opening and closing vectors; external returns; transfer and cohort links; allocation record	A_j attributable raw exchange totals	`ilcd-attributional-2010`
`release_denominator`	first_release	Q = sum of actual dry-surface net glass mass of uniquely first-released panes after required tests. Pre-release destructive samples and failures are excluded. Newly released closing FG is already in Q; never add it as another output. Shipment, return, repair and reinspection do not add Q.	cp_release; unique first-release registry; net glass mass; required tests	Q in kg	`pilkington-toughened-glass`; `gpd-tempering-control-2023`
`normalize_exchange`	all inventory rows	q_j = A_j / Q for Q > 0. Execute this division once after convert_raw and attribute_raw; q_j is the exchange per 1 kg reference flow. For Q = 0 retain A_j and all raw records with no unit result. Cards and protocol aggregation only reference this same result and never divide again.	A_j; Q; convert_raw; attribute_raw; cp_release	q_j per 1 kg reference flow	`ilcd-attributional-2010`
`physical_gates`	all inventory rows	Manufacturing: opening raw glass stock + opening glass WIP + external raw glass received = closing raw glass stock + closing glass WIP + Q + dry-glass manufacturing wastes + any other independently identified physical glass outputs. Water/material additions, dust and moisture are balanced independently. FG service: opening FG + first-release internal receipt + external glass returns + measured repair additions = closing FG + gross glass dispatch + external glass return sent + FG waste + measured repair removals and water/air losses. All masses are on stated consistent phase/moisture bases. Consolidation cancels first-release internal receipt against manufacturing transfer; it does not add Q and new closing FG as independent external outputs.	cp_preparation; cp_toughening; cp_release; cp_handling; independent phase and species measurements	separate and consolidated physical mass and relevant element checks	`gpd-tempering-control-2023`; `landglass-wash-dry-2020`
`packaging_ledger`	all inventory rows	For EACH packaging article separately: opening empty + opening attached WIP + opening attached FG + opening reusable + purchases + external returns received = closing empty + closing attached WIP + closing attached FG + closing reusable + gross physical outgoing + external returns sent + waste. Categories are mutually exclusive. Gross outgoing includes packaging attached to gross glass dispatch even if that glass later returns. Internal reuse/transfer cancels; it is not a new purchase, Q, yield or automatic co-product. Retain inherited per-exchange burden vectors and actual repeated-service allocation separately from this physical mass ledger.	cp_handling; article-specific stocks; purchases; external receipts and dispatch; returns; waste; inherited vectors	each article physical ledger and attributed burden reconciliation	`ilcd-attributional-2010`; `pilkington-toughened-glass`
asset_manufacture_share	existing capital/reusable manufacture attribution	For each included original asset manufacture vector B, f_current = u_current / D only after the persistent ledger verifies the supported whole installed-service denominator, all beneficiaries and prior assigned shares. Attribute f_current * B once to the actual beneficiary before the existing single reference normalization. Check prior_shares + all current/new beneficiary shares <= 1; carry the remaining original balance. Capacity revisions reconcile the historical ledger. Full physical asset/packaging mass and actual gross stocks/returns never receive f_current. Unknown D or history leaves the final attributed result unavailable, without suppressing actual repair/replacement/service burdens.	asset_id; original_B; u_current; D; historical_beneficiaries; prior_shares; capacity_evidence	conserved attributed manufacture vector

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	all inventory rows	Retain the full native flow restrictions within every inventory description and actual provider matching evidence. UUID is an identity, not an amount or process approval. Auxiliary unresolved UUIDs remain concrete physical exchanges.	Direct native identities; supplier state and composition; actual product tests
dq_period	all inventory rows	Use a complete representative declared period with all campaigns and start/stop idle and zero-output records. Retain original release cohorts and original delivery links across period boundaries.	Raw meters; period/cohort ledger; original delivery reversals
dq_water	all inventory rows	Independently measure free surface water, wastewater, sludge moisture and evaporation; reaction water, structural water and dissolved species cannot be inferred from one residual. Keep actual receiving medium. Thermal stress treatment alone supplies no reaction stoichiometry.	Independent samples and phase/species records; moisture and tank inventories
dq_stocks	all inventory rows	Separate physical stock quantities from each inherited exchange vector in WIP, FG, oil charge and water systems; do not set missing history to zero. Carry retained burdens and allocate actual use to the relevant cohort.	Opening/closing physical stocks; exchange-specific historical records
dq_unknown	all inventory rows	Preserve unknown, measured zero, not applicable and below-detection separately. Supplier/auxiliary identity and future foreground quantities are collection requirements, not fabricated defaults or automatically missing methodology. Actual unknown core relationships require a hold.	Gap register; detection limits; uncertainty and sensitivity record

9. Validation Rules

rule_id	Applies to	Rule	source_ids
`validate_identity`	all dataset identities	Verify the input is actual annealed uncoated float and the terminal is first-released flat monolithic thermally toughened soda-lime safety glass. Keep heat-strengthened and laminated counterexamples explicit; no generic Safety glass UUID certifies route, dimensions, strength or legal conformity. Check every selected native name, synonym, CAS, form, route, geography, medium, type and property. Respect supply restrictions on each row and use a different verified identity when incompatible.	`pilkington-toughened-glass`; `gpd-tempering-control-2023`
`validate_balance`	manufacturing FG and combined physical gates	Close manufacturing and FG-service mass gates independently and then cancel matching internal transfers. Do not add closing FG to Q as production. Test dry-glass, free-water and relevant elemental subbalances using independent measured species/phase data. Heating is physical stress treatment, not a basis to invent reaction water, oxygen consumption or carbonate CO2. Preserve actual additional reactions or coating decomposition if observed; such a changed route needs explicit review.	`gpd-tempering-control-2023`; `landglass-wash-dry-2020`
`validate_measurement`	all raw records and calculations	Require traceable unit conversion before allocation and the single normalize_exchange operation. Do not divide in protocol collection or again in cards/aggregation. Preserve Q=0 raw burdens without a unit result. Distinguish measured zero, absent, unknown and below-detection-limit. Validate period/cohort stocks and per-exchange historical vectors; a scalar stock mass cannot substitute for its burden vector.	`ilcd-attributional-2010`
`validate_packaging`	each packaging article	Require a complete material-specific physical ledger including empty, WIP-attached, FG-attached and reusable opening/closing stocks, purchases, external returns received, gross physical dispatch, external returns sent and waste. Internal reuse cancels. These flows do not change glass Q or yield or create automatic co-products. Reconcile count/area to independently measured mass for the actual article.	`ilcd-attributional-2010`; `pilkington-toughened-glass`
`validate_completeness`	dataset handoff	Missing actual terminal evidence, missing manufacturing operations or unknown core burden relationships prevent a completed dataset claim. Ordinary supplier/activity measurements and unresolved auxiliary UUIDs are future data-production requirements rather than evidence of absent exchanges. Report each gap, failed retrieval, unresolved applicability and uncertainty without treating a technical/schema check as scientific or translation approval.	`pilkington-toughened-glass`; `ilcd-attributional-2010`
validate_asset_manufacture_conservation	existing capital/reusable manufacture attribution	For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness.

System boundary rules · 7

Rule ID	Applies to	Rule	Source IDs
`system_boundary_rule_1`	foreground_system_boundary	The following rules apply together. Retain every actual operation and attributable burden; zero output or failure is not a reason to delete it.
`boundary_route`	all manufacturing	Start at receipt of full annealed uncoated soda-lime float stock sheets. Include stock handling; actual cutting and edge grinding; required holes before heat treatment; washing and drying; electric roller-furnace heating; forced-air quench; inspection and destructive sampling; any specified heat soak and rejection; first release; and actual downstream storage/packing/handling service. This is a technical synthesis across primary sources, not a claim of one SKU or factory. No furnace temperature, density, strength, yield, energy, lifetime or certification default is set.	pilkington-toughened-glass, gpd-tempering-control-2023, landglass-wash-dry-2020, glaston-fc-flat-tempering, bavelloni-ve-edgers
`boundary_upstream`	all purchased inputs	Attach actual compatible upstream burdens to full supplied sheets and each utility, supplied formulation, tooling and packaging input. Do not reproduce melting, tin-bath forming or annealing inside this conversion boundary. Do not replace conversion with purchased safety-glass packaging. Same-category external safety glass is an explicitly separate burden-bearing resale/service input and is excluded from newly manufactured Q.	pilkington-toughened-glass
`boundary_release`	first_release and handling	Q is the sum of uniquely identified panes passing first required release in the reporting cohort, measured as net glass mass with dry surfaces. Destructive samples, pre-release rejects and opening already-released FG are not Q. New closing FG has already crossed Q and must not be added as another manufacturing output. Track the physically distinct FG service ledger and cancel internal Q transfers. Deliveries, returns, reinspection and repairs never create new Q. Keep original release and delivery references; reverse only the original delivery-ledger assignment before reassigning returned glass, never the original first release or its manufacturing burden. Newly released closing FG retains its complete manufacturing burden inside Q. Observed incremental post-release services follow the original release cohort and declared service interval.	pilkington-toughened-glass, gpd-tempering-control-2023
`boundary_complete`	every actual exchange	Include failed runs, zero-output periods, warmup/cooldown, idle, start/stop, cleaning, test breakage, rework, utilities, captured waste, leaks and emissions. Unlisted actual inputs or exports require additional chemically/physically specific atomic rows with actual identities, properties, conditions and destinations; no hidden other, zero or lumped balance category is allowed. Absent exchanges require actual route evidence. Retain monitored unknowns and uncertainty; do not force balance closure.	gpd-tempering-control-2023, landglass-wash-dry-2020
`boundary_fluid`	WIP and non-WIP stocks	Maintain quantities and a separate inherited vector for every exchange in opening/closing glass WIP, raw stocks, installed lubricants, wash tanks, recirculating liquids and other equipment charges. A stored litre or kilogram is distinct from embodied energy or each upstream exchange. Assign only attributable use/losses/removal, carry retained PRE-release or unused-stock burdens forward and cancel internal transfers. Newly released FG is already inside Q; its complete manufacturing vector is carried for traceability without reducing manufacturing A_j. Equipment fluids are not WIP panes. For any actual external steam/heat or condensate return, add separate atomic supply and Product-return flows with actual mass, temperature, pressure, phase and enthalpy and the supplier water/energy convention; this electric air-quench route does not presume a boiler.	gpd-tempering-control-2023, landglass-wash-dry-2020
`boundary_exclusions`	scope and terminal	Exclude heat-strengthened-only panes, chemical strengthening, lamination, coated/enamelled/printed glass manufacture, bending, mirror silvering, insulating-unit assembly, framing, installation and use/end-of-life from this specific route. Fully toughened monolithic glass is not automatically suitable for post-breakage retention or a laminated balustrade. Actual conformity and performance are manufacturer/test records, not inferred from a safety label. A materially different terminal or route needs its own methodology review.	pilkington-toughened-glass, gpd-tempering-control-2023

Allocation rules · 6

Rule ID	Applies to	Rule	Source IDs
`allocation_rule_1`	foreground_burden_allocation	The sequence below applies only to attributional multifunctional processes. Industrial manufacturing documents do not by themselves establish LCA allocation rules.
`allocation_subdivide`	attributional manufacturing and services	Use attributional modelling only. Identify exclusive sheet, machine, batch and service records first; subdivide or virtually subdivide wherever quantitative technical relationships can isolate an exchange. Keep manufacturing and FG services separate and allocate each to the relevant release cohort. Do not choose arbitrarily between physical and economic allocation.	ilcd-attributional-2010
`allocation_causality`	residual shared exchanges	For each exchange remaining shared, identify and document the determining physical causal relationship. Do not apply one mass ratio to every flow. Different thickness, loading, heating recipe and quench intensity require actual measurements/models; area, time or mass are not interchangeable automatic keys. For shared rack/storage/transport services demonstrate the actual limiting capacity and duration/distance. Preserve failed-load and idle burdens and document any distortion.	ilcd-attributional-2010, gpd-tempering-control-2023
`allocation_residual`	genuinely inseparable residual multifunctionality	Only for genuinely residual shared flows after the preceding steps, use contemporaneous market values of actual co-functions in their real condition and amounts at the same common-process exit/entry gate. Strip downstream-only finishing, transport, packaging and margin from remote prices. If the correct value cannot be established retain a review hold and quantify sensitivity; do not invent a fixed percentage. This concerns multifunctional processes, not QFD comparison of multifunctional consumer products.	ilcd-attributional-2010
`allocation_waste`	rejects returns and packaging	Waste and internal recirculation are not automatic co-products, negative production or avoided-production credits. Establish actual product/waste status, ownership, treatment and burden transfer for external cullet and retired packaging. Preserve original burdens and actual incremental repair/service loads; never erase failure burdens or count returning racks as new purchases.	ilcd-attributional-2010
`asset_manufacture_conservation`	existing capital/reusable manufacture attribution	Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

Validation rules · 6

Rule ID	Applies to	Rule	Source IDs
`validate_identity`	all dataset identities	Verify the input is actual annealed uncoated float and the terminal is first-released flat monolithic thermally toughened soda-lime safety glass. Keep heat-strengthened and laminated counterexamples explicit; no generic Safety glass UUID certifies route, dimensions, strength or legal conformity. Check every selected native name, synonym, CAS, form, route, geography, medium, type and property. Respect supply restrictions on each row and use a different verified identity when incompatible.	pilkington-toughened-glass, gpd-tempering-control-2023
`validate_balance`	manufacturing FG and combined physical gates	Close manufacturing and FG-service mass gates independently and then cancel matching internal transfers. Do not add closing FG to Q as production. Test dry-glass, free-water and relevant elemental subbalances using independent measured species/phase data. Heating is physical stress treatment, not a basis to invent reaction water, oxygen consumption or carbonate CO2. Preserve actual additional reactions or coating decomposition if observed; such a changed route needs explicit review.	gpd-tempering-control-2023, landglass-wash-dry-2020
`validate_measurement`	all raw records and calculations	Require traceable unit conversion before allocation and the single normalize_exchange operation. Do not divide in protocol collection or again in cards/aggregation. Preserve Q=0 raw burdens without a unit result. Distinguish measured zero, absent, unknown and below-detection-limit. Validate period/cohort stocks and per-exchange historical vectors; a scalar stock mass cannot substitute for its burden vector.	ilcd-attributional-2010
`validate_packaging`	each packaging article	Require a complete material-specific physical ledger including empty, WIP-attached, FG-attached and reusable opening/closing stocks, purchases, external returns received, gross physical dispatch, external returns sent and waste. Internal reuse cancels. These flows do not change glass Q or yield or create automatic co-products. Reconcile count/area to independently measured mass for the actual article.	ilcd-attributional-2010, pilkington-toughened-glass
`validate_completeness`	dataset handoff	Missing actual terminal evidence, missing manufacturing operations or unknown core burden relationships prevent a completed dataset claim. Ordinary supplier/activity measurements and unresolved auxiliary UUIDs are future data-production requirements rather than evidence of absent exchanges. Report each gap, failed retrieval, unresolved applicability and uncertainty without treating a technical/schema check as scientific or translation approval.	pilkington-toughened-glass, ilcd-attributional-2010
`validate_asset_manufacture_conservation`	existing capital/reusable manufacture attribution	For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness.
