1. Scope and Applicability

This bounded manufacturing method starts with purchased PVC resin and separately supplied formulation ingredients. It includes onsite batching/plasticisation, calendering and chipping, chip blending/scattering and consolidation into a compact through-pattern sheet, factory UV finishing, annealing, cooling, trimming/rolling, tests and first quality release. It covers non-foamed, non-conductive, unbacked homogeneous flexible PVC flooring rolls. A thin protective finish does not turn the body into a printed multilayer floor. The representative branch uses DOTP, ground calcium carbonate, a supplied calcium-zinc stabilizer formulation and a supplied UV-curable polyurethane-acrylate floor-coating formulation; actual pigment and processing additions remain separately identified. [ahf-homogeneous-2023; prodinex-pvc-2025; arkema-vinyl-formulation]

This is a transparent technical synthesis, not a claim that the sources describe one SKU, recipe, factory or contemporary order. AHF documents the complete homogeneous sheet route and real coated roll endpoint. Prodinex independently documents adjacent dryback flooring ingredients but uses a different multilayer pressing route. Arkema demonstrates ingredient choices and alternative additives in LVT substrates, including a separate tin-stabilized rigid formulation; neither is homogeneous-sheet production proof. No source mass fractions, phr, size, density, energy, losses, lifetime, certification or allocation key is a default here. In particular the Prodinex steam supply and waste/packaging boundary statements are not transferred; the AHF area allocation is not this method's allocation rule.

Exclude paper wallpaper, paper-backed vinyl wallpaper, plastic wall/ceiling coverings, self-adhesive stock, printed/decor-film multilayer flooring, SPC/WPC rigid cores, backed/foam/textile products, conductive or safety-grit constructions, PVC-free polymers, linoleum, tiles/block-slicing routes, purchased finished-floor repacking and integrated polymerisation. A materially different construction or manufacturing route needs separate applicability review; this subset does not cover all CPC 36910.

Field	Value
Reference amount	1
Reference product flow	Floor coverings of plastics, in rolls or in the form of tiles, wall or ceiling coverings of plastics `97494e7c-4947-433c-9b86-cf2baa643329`
Reference flow property	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`

Reference unit	kg
Required qualifiers	PVC resin form and supplier grade; each whole purchased formulation and its composition/assay/carrier; DOTP identity and CaZn system; filler mineral/particle specification; each pigment and processing additive; chip/consolidation route and actual thermal equipment; unbacked non-foamed non-conductive through-pattern body; UV finish SKU and supplied wet/solids chemistry and cure evidence; coating retention and any measured volatiles; roll dimensions and net conditioned mass plus measured kg/m2; grade-specific acceptance tests; first-release Q and unique release/rework/return IDs; complete WIP/FG stocks and each inherited exchange burden vector; site/period and measured voltage/provider; cooling/heat supply and actual return states; each package composition and gross-shipment/return ledger; native generic-flow restrictions and upstream compatibility

Declare every qualifier in metadata, process notes, reference comments or equivalent dataset fields. The native reference UUID is a broad manufactured-plastics covering family with no fixed polymer, formulation, CAS, size, geography or provider. Its finished-product/production-mix-at-plant context admits this one qualified floor roll; it does not identify a wall covering, tile basket, certified grade or ready-made background dataset. Preserve each selected card's full restrictions when consuming guidance. Net kg does not establish equal installed area or service life.

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	Q is unique newly first-quality-released net flooring kg for the same grade/state cohort, using calibrated gross-minus-core/package tare at a declared conditioning/moisture state. Include retained cured finish. Retesting, shipping or returning an already released roll never creates Q; closing FG already contains its first-release Q.
area_conversion	reference product	Mass and area	kg; m2	Measure net same-lot finished mass m and usable roll area S independently; g = m/S kg/m2 and an area s converts to s*g kg. Exclude core, overlap, package and test/reject area. Do not copy source grammage, infer density from thickness or guess kg per roll.
supply_basis	all inventory rows	Mass and supplied state	kg	Each purchased formulation is one complete supplied exchange counted once. Active fraction, carrier water and assay are subledgers, not additional purchases. Actual onsite formulation uses each separately purchased ingredient, energy and loss. Supplied nonvolatile solids do not automatically equal retained cured mass.
energy_units	make_electricity; fg_electricity	Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66`	MJ	The native energy chain is Units of energy 93a60a57-a3c8-11da-a746-0800200c9a66 with reference MJ. Convert integrated kWh to MJ using 3.6 before attribution; measured power rates alone require integration. Nameplate power is not consumption.
physical_state	all inventory rows	Mass and actual state	kg; m3; h	Integrate only genuine rates. Integrated gas/liquid volume is already an amount. Volume-to-mass conversion requires independently measured density of that substance at its actual composition/T/P; distinguish standard/actual and wet/dry gas. Do not apply water density to coating, solvent, effluent or gas or infer density from secondary flow properties.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Delivered PVC resin, each separately supplied formulation ingredient and utilities; inherited WIP and internal regrind with original exchange burden vectors
starting_condition_role	Foreground receipt gate; upstream resin/ingredient/coating manufacture retained in matched supplier datasets
product_classification_scope	Qualified homogeneous flexible PVC floor rolls within CPC 36910, independent of native broad flow labels
recursive_input_rule	Purchased finished flooring is a distinct upstream product with disclosed omitted stages, never a substitute for resin compounding. Internal chips, sheet trim and rework retain burden history and cancel as internal transfers.
upstream_dataset_requirement	Match actual polymer/formulation, supplied wet state, mineral grade, coating system, electricity delivery voltage/geography/period, water treatment and packaging providers; include inbound transport explicitly. A flow UUID alone proves no provider compatibility.
disclosure	Report manufacture through first release and a separately dated observed FG packing/storage/handling/dispatch ledger. Disclose unobserved service tails, capital treatment, background/transport links and separate installation/use/end-of-life modules.

rule_id	Applies to	Rule	source_ids
boundary_route	floor_make	Retain every real mixing/plasticisation/calendering/chipping, chip handling/consolidation, coating/UV cure, annealing/cooling, trimming/rolling/test step, including failed and zero-output lots, startup/shutdown, idle, cleanup, purge, test samples and actual regrinding/rework. The chip intermediate is not a purchased finished floor.	ahf-homogeneous-2023
boundary_formulation	floor_make	Identify every separately purchased ingredient and whole supplied formulation. The listed branch is a technical synthesis, not a universal recipe. Add a distinct physically named input/outlet card for every actual unlisted pigment, additive, cleaning reagent, filter, lubricant, fuel, refrigerant or treatment chemical before dataset use; unknown amounts are not zero and cannot be hidden under other.	ahf-homogeneous-2023; prodinex-pvc-2025; arkema-vinyl-formulation
boundary_utilities	floor_make	Record actual cooling/heating circuits and inlet/outlet states. The representative electric heating/UV branch assumes no combustion or purchased steam. If actually supplied, add the specific heat/steam/hot-water Product input and each real condensate/heat-exchange-water Product return, mass/T/P/enthalpy and provider energy/water convention. A boiler requires its own measured fuel, air/water, ash and individual species; an adjacent EPD's steam is not evidence of a circuit here.	ahf-homogeneous-2023; prodinex-pvc-2025
boundary_service	fg_service	Keep first release Q separate from subsequent packing, storage, handling and dispatch. Pair internal Q transfer once. Keep opening/closing FG, physical returns, original shipment reversal and incremental service/rework by original release lot. Old lots retain old denominators/burden vectors; their delivery or reinspection creates no new Q.	ilcd-allocation-2010
boundary_water_species	floor_make	Keep total physical mass and relevant C/Cl/Ca/Ti balances independent from measured chemical-species evidence. Water in a formulation, retained/free/phase water and actual reaction water are distinct; fusion, annealing or UV crosslinking does not justify default reaction water. Do not solve two unknown emissions/water quantities with one residual or convert VOC/COD into an assumed chemical mass.	ahf-homogeneous-2023; arkema-vinyl-formulation

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
floor_make	Ingredient-to-first-release flooring manufacture	required	Selected homogeneous chip-consolidation and UV-finish route including actual conditional additions/outlets	Foreground production and WIP/regrind burden carry	per 1 kg reference flow
fg_service	Observed finished-goods services	required	Original release lot and actual observed interval; disclose open service tails	Separate FG/package/return and incremental service ledger	per 1 kg reference flow

For every non-reference card, A_i is the undivided attributed exchange numerator in that card's own unit after raw-unit conversion and stock/burden reconciliation. Section 8 normalize_once performs A_i / Q exactly once. Collection methods retain raw totals; the aggregation field states the final reporting basis only. Card text and aggregation references do not repeat division. Conditional absence needs actual route evidence; unknown is not not_applicable. Every physical stream is separate even when one protocol or meter serves several cards.

Ground limestone filler (`limestone`)

Native Product is limestone filler/CaCO3 received at plant with production-mix context. It has no CAS, fixed grade, particle size, ground/precipitated route, geography, supplier or general comment. Its CPC 15200 is a broad calcareous-rock grouping; the coherent material identity does not prove filler quality. Use only the actual ground-limestone filler with measured moisture/purity/particle and any surface treatment; match its upstream provider independently, not quicklime or precipitated carbonate.

DOTP plasticizer (`dotp`)

Native Product is clear liquid DOTP CAS 6422-86-2, also dioctyl terephthalate, synthetic plasticizer at factory; route text describes 2-ethylhexanol plus terephthalic acid. It is not DEHP/DINP or the ortho-phthalate isomer. Native CPC 34170 is an imperfect generic organic grouping, not evidence overriding the coherent CAS/name/route. No fixed purity, grade, geography or provider is supplied. Record whole supplied grade and impurities once; any materially different chemical or synthesis/provider needs independent compatibility.

Supplied calcium-zinc stabilizer (`cazn_stabilizer`)

One whole supplied CaZn formulation with actual carrier, salts, assay and supplier specification; not pure calcium or zinc stearate. Embedded carrier/additives remain subledgers.

Titanium dioxide pigment (`titanium_dioxide`)

Conditional separately purchased TiO2 pigment, with actual rutile/anatase form, surface treatment and supplied composition. If present inside a purchased masterbatch, count that whole masterbatch once instead and add its named card; do not buy its TiO2 again.

Epoxidized soybean oil (`esbo`)

Conditional one purchased epoxidized soybean oil grade when actually added; record epoxy specification and supplied composition.

Supplied UV floor finish (`uv_finish`)

One whole ready-to-apply purchased floor finish, on its actual supplied wet mass. Record oligomer/reactive diluent/photoinitiator, water and solvent fractions as composition subledgers and verify cure/retention and any measured loss; do not assume 100% solids, zero VOC or water-forming condensation. AHF supports UV coating and the adjacent Prodinex case names polyurethane acrylate; this synthesis does not identify AHF coating chemistry or a shared SKU.

Manufacturing electricity (`make_electricity`)

Native Product is customer-side <1 kV alternating-current consumption mix and grid-average supply, not hydropower generation, voltage-transformation service or a power-plant output. The native supply geography is CN. Bind this UUID only at an actual Chinese <1 kV grid-average customer gate and match provider/period independently; another geography or voltage requires its own verified identity. The Korean AHF case does not authorise using this CN flow for Korea. Reconcile actual transformer/distribution losses at the declared gate without double purchasing the same electricity. Native reference property is Net calorific value/MJ, not Mass. Meter every real mixing, heating, calender, chip handling/consolidation, UV, annealing, cooling, trimming, extraction, compressor and cleanup/idle load. Thermal power supplies are actual equipment records, not an assumed steam circuit. Measurement support chain: Units of energy 93a60a57-a3c8-11da-a746-0800200c9a66, reference MJ.

Old released-floor rework receipt (`returned_floor_rework`)

Native Product is a manufactured plastic-covering family at plant, with no fixed polymer, CAS, recipe, dimensions, grade, geography, provider or performance; synonyms are empty. Its floor/wall/ceiling alternatives are not a mixed exchange here: this card is one specified compact unbacked non-conductive homogeneous flexible PVC floor roll with cured UV finish. Neither the broad classification nor UUID establishes background compatibility or installed service equivalence. Conditional physical receipt paired with fg_service rework_to_make; retain original release/shipment and inherited burden vectors.

Net oxygen uptake from air (`oxygen_uptake`)

Conditional independently evidenced net molecular O2 uptake where actual ozone generation or coating chemistry consumes it. Keep oxygen, ozone and any water/reaction products as separate species; do not infer uptake or reaction water from a total mass residual. Bulk recirculating/pass-through air is not automatically consumed oxygen. Native CAS 7782-44-7; Elementary resource from air, renewable element resource, Mass/kg.

Newly first-released flooring (`released_floor`)

Native Product is a manufactured plastic-covering family at plant, with no fixed polymer, CAS, recipe, dimensions, grade, geography, provider or performance; synonyms are empty. Its floor/wall/ceiling alternatives are not a mixed exchange here: this card is one specified compact unbacked non-conductive homogeneous flexible PVC floor roll with cured UV finish. Neither the broad classification nor UUID establishes background compatibility or installed service equivalence. This is the only reference output: newly accepted net Q, including retained finish, after actual cure/conditioning and quality tests. Exclude cores/packages/rejects and previously released rework. Q transfers once to FG and cancels internally in a combined physical ledger; do not add closing FG as another production output.

Conditional actual whole packaging article physically shipped with the product, measured at gross outbound movement and matched to its own package ledger and original release cohort. Preserve this external exit even if the same packaging is later returned. Do not net it against returns, subtract it by allocation shares, add it to flooring Q, create another purchase or assume a coproduct credit. Owner-directed empty pallet returns remain the separate pallet_return_out exchange. Conditional one whole actual winding tube with its adhesive included once; distinguish support core from flooring. Keep individual opening empty/attached-WIP/attached-FG/reusable stocks, purchases and external returns received against closing stocks, gross physical shipping, external returns and waste. Internal reuse cancels and is not a purchase, Q or automatic coproduct. Tiangong flow UUID is unresolved; retain this single specific exchange and verify complete supply/chemistry/form/destination and compatible identity before actual dataset use, without a generic substitute.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_scenario	all inventory rows	This method is attributional and applies where allocation is required by the study goal/context. Establish actual functions and physical/legal/economic state of every output; the industrial manufacturing sources do not establish LCA allocation. Do not freely choose between physical/economic keys or claim complete ILCD/EPD conformance.	ilcd-allocation-2010
allocation_subdivide	floor_make; fg_service	First collect dedicated operations and exclusive inputs by grade, lot and service. Use real subdivision, then technically justified virtual subdivision where a quantitative relationship identifies exclusive exchanges; record infeasibility and potential distortion for any retained shared process. Internal chips/regrind retain original burdens, never displacing a second purchase by an automatic credit.	ilcd-allocation-2010
allocation_causality	all inventory rows	For each remaining exchange identify and substantiate the determining physical causal relationship to each co-function, including the actual load/temperature/cure/time/space mechanism as relevant. Material incorporation, heat duty and occupied space-time need not use the same key. Surface-area or mass shares alone are not causal proof, even if used by an industrial EPD. Retain drivers, sums and sensitivity.	ilcd-allocation-2010
allocation_residual	all inventory rows	Only genuinely residual exchanges without a supported determining causal relationship use contemporaneous market values at the common process gate in the actual condition, quality, quantity and packaging state. Remove evidenced subsequent processing, storage, packaging and transport value. Document price basis, missing/negative/zero values and sensitivity; missing values need review, not equal or fixed shares.	ilcd-allocation-2010
allocation_conserve	all inventory rows	All assigned shares reconcile to the undivided exchange. A useful externally transferred material requires actual specification and a justified function; waste fees or recovery do not automatically create coproducts, zero burdens or avoided-production credits. Waste/recycling cases needing an additional method remain explicitly unresolved until supported; this PCR supplies no default recycled-content or end-of-life formula.	ilcd-allocation-2010
allocation_fg	fg_service	Assign each observed service to its original released lot and preserve old denominators. Returns reverse their actual prior shipment/vector and receive only real incremental service/rework. Unattributed startup/idle/failed-campaign loads remain visible and require justified assignment; they cannot disappear because output is zero.	ilcd-allocation-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

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.

All protocols collect undivided raw records, never pre-normalized intensities. Each reported exchange is generated once by normalize_once; aggregation_rule below declares that reporting basis. Keep unconverted readings, conversions, attribution decisions, per-exchange inherited vectors and the final computation as separate records.

Deduplicate by original first-release ID and exclude old released rework, repeats and rejected tests. Sum net unique new released mass as Q; independently measure usable area for any area conversion.	kg; m; m2	every roll and release decision	same campaign and stock cutoff	same specified product grade and physical state	per 1 kg reference flow	calibration/tare records; first-release register; test results; dedup/reject trail; actual area/mass sampling
cp_stock	floor_make	Every raw exchange and chip/sheet/WIP/rework transfer	lot_and_burden_vector_record	lot_id; parent_lot; opening_WIP; closing_WIP; opening_in_process; closing_in_process; opening_in_process_B_i; closing_in_process_B_i; internal_chip; internal_regrind; current_raw_exchange_i; opening_B_i; closing_B_i; transfer_B_i; cohort_id; historical_Q; failure_load; allocation_record; physical_outlet	Track quantity and every exchange-specific inherited burden vector through mixing/chips/sheet/cure and real rework. Carry opening vectors plus attributable current undivided additions and reconcile closing/transfer vectors without equating mass fraction to every exchange burden. No hypothetical same-intensity stock is assumed. Preserve failed-campaign loads even if Q is zero. Include separately accounted in-process inventories, including cooling-loop water and actual equipment/finish charges, with their own physical states and inherited vectors. Identify and eliminate overlap with raw stocks, WIP and FG.	kg and each exchange's native unit	each lot transfer and opening/closing cutoff	all relevant prior-lot histories plus complete current campaign	line/WIP/regrind/rework interfaces with matching cohorts	per 1 kg reference flow	lot genealogy; measured stock; per-exchange vector reconciliation; historical release/return records; missing-vector disclosure

Reconcile the FG gate independently; carry old cohorts separately from new Q. Pair internal transfers with manufacture and cancel only those matched transfers in consolidation.	kg and each exchange's native unit	every stock/shipment/return/rework movement	original histories and declared observed FG interval	specified FG store and original release cohorts	per 1 kg reference flow	stocktake; dispatch/return slips; historic burden records; commercial versus physical return distinction
cp_fg_energy	fg_service	fg_electricity	service_meter_record	meter_id; kWh_start; kWh_end; voltage; provider; geography; original_release_id; occupied_space; duration; handling_load; idle_cleanup; attribution_driver	Separately meter actual packing/storage/handling/loading and real idle/cleanup; convert raw energy before attribution, assign to original release lot using documented service mechanism and carry its historic denominator. Do not put old-cohort services in new production Q.	kWh; MJ	each service interval	explicit observed service window including old FG	actual FG service equipment and customer-side supply	per 1 kg reference flow	service meters; load/space-time records; calibration; cohort assignment and open-tail disclosure

Delivered ingredient/coating containers need their own specifically named input/return/waste cards when present, whether separately invoiced or bundled. Attached shipping packages follow gross physical shipments including repeats, not net product Q. Count internal reuse as a cancelling transfer and external returns as their own movements. Preserve real per-article mass if purchasing counts; never guess kg/item.	kg; item with separately measured kg/item	each receipt/application/shipment/return/disposal and cutoff	full supply and FG service interval with prior cycle history	each named package across raw/WIP/FG/reusable locations	per 1 kg reference flow	weighing; purchase/return records; packaging specifications; stocktake; cycle/repair and gross-shipment reconciliation

System boundary rules · 5

Rule ID	Applies to	Rule	Source IDs
`boundary_route`	floor_make	Retain every real mixing/plasticisation/calendering/chipping, chip handling/consolidation, coating/UV cure, annealing/cooling, trimming/rolling/test step, including failed and zero-output lots, startup/shutdown, idle, cleanup, purge, test samples and actual regrinding/rework. The chip intermediate is not a purchased finished floor.	ahf-homogeneous-2023
`boundary_formulation`	floor_make	Identify every separately purchased ingredient and whole supplied formulation. The listed branch is a technical synthesis, not a universal recipe. Add a distinct physically named input/outlet card for every actual unlisted pigment, additive, cleaning reagent, filter, lubricant, fuel, refrigerant or treatment chemical before dataset use; unknown amounts are not zero and cannot be hidden under other.	ahf-homogeneous-2023, prodinex-pvc-2025, arkema-vinyl-formulation
`boundary_utilities`	floor_make	Record actual cooling/heating circuits and inlet/outlet states. The representative electric heating/UV branch assumes no combustion or purchased steam. If actually supplied, add the specific heat/steam/hot-water Product input and each real condensate/heat-exchange-water Product return, mass/T/P/enthalpy and provider energy/water convention. A boiler requires its own measured fuel, air/water, ash and individual species; an adjacent EPD's steam is not evidence of a circuit here.	ahf-homogeneous-2023, prodinex-pvc-2025
`boundary_service`	fg_service	Keep first release Q separate from subsequent packing, storage, handling and dispatch. Pair internal Q transfer once. Keep opening/closing FG, physical returns, original shipment reversal and incremental service/rework by original release lot. Old lots retain old denominators/burden vectors; their delivery or reinspection creates no new Q.	ilcd-allocation-2010
`boundary_water_species`	floor_make	Keep total physical mass and relevant C/Cl/Ca/Ti balances independent from measured chemical-species evidence. Water in a formulation, retained/free/phase water and actual reaction water are distinct; fusion, annealing or UV crosslinking does not justify default reaction water. Do not solve two unknown emissions/water quantities with one residual or convert VOC/COD into an assumed chemical mass.	ahf-homogeneous-2023, arkema-vinyl-formulation

Allocation rules · 7

Rule ID	Applies to	Rule	Source IDs
`allocation_scenario`	all inventory rows	This method is attributional and applies where allocation is required by the study goal/context. Establish actual functions and physical/legal/economic state of every output; the industrial manufacturing sources do not establish LCA allocation. Do not freely choose between physical/economic keys or claim complete ILCD/EPD conformance.	ilcd-allocation-2010
`allocation_subdivide`	floor_make; fg_service	First collect dedicated operations and exclusive inputs by grade, lot and service. Use real subdivision, then technically justified virtual subdivision where a quantitative relationship identifies exclusive exchanges; record infeasibility and potential distortion for any retained shared process. Internal chips/regrind retain original burdens, never displacing a second purchase by an automatic credit.	ilcd-allocation-2010
`allocation_causality`	all inventory rows	For each remaining exchange identify and substantiate the determining physical causal relationship to each co-function, including the actual load/temperature/cure/time/space mechanism as relevant. Material incorporation, heat duty and occupied space-time need not use the same key. Surface-area or mass shares alone are not causal proof, even if used by an industrial EPD. Retain drivers, sums and sensitivity.	ilcd-allocation-2010
`allocation_residual`	all inventory rows	Only genuinely residual exchanges without a supported determining causal relationship use contemporaneous market values at the common process gate in the actual condition, quality, quantity and packaging state. Remove evidenced subsequent processing, storage, packaging and transport value. Document price basis, missing/negative/zero values and sensitivity; missing values need review, not equal or fixed shares.	ilcd-allocation-2010
`allocation_conserve`	all inventory rows	All assigned shares reconcile to the undivided exchange. A useful externally transferred material requires actual specification and a justified function; waste fees or recovery do not automatically create coproducts, zero burdens or avoided-production credits. Waste/recycling cases needing an additional method remain explicitly unresolved until supported; this PCR supplies no default recycled-content or end-of-life formula.	ilcd-allocation-2010
`allocation_fg`	fg_service	Assign each observed service to its original released lot and preserve old denominators. Returns reverse their actual prior shipment/vector and receive only real incremental service/rework. Unattributed startup/idle/failed-campaign loads remain visible and require justified assignment; they cannot disappear because output is zero.	ilcd-allocation-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 · 8

Rule ID	Applies to	Rule	Source IDs
`validate_scope`	reference product	Verify actual compact through-pattern PVC roll construction and the complete chip-consolidation/UV-finish route, including real raw-material receipt and final tests. A generic covering UUID or CPC leaf alone does not establish applicability.	ahf-homogeneous-2023
`validate_reference`	released_floor	Verify all required qualifiers, one unique first-release Q, actual conditioned net mass/tare and retained finish, same bilingual reference link/basis, and no repeated release or FG double count.	ahf-homogeneous-2023
`validate_accounting`	all inventory rows	Verify unit conversion and real attribution before the undivided A_i; perform normalize_once once only for positive original-cohort Q. Q-zero loads remain visible without a unit result. Check complete finite measurement relationships without calling unknowns passed.	ilcd-allocation-2010
`validate_gates`	floor_make; fg_service	Independently reconcile manufacturing, FG and consolidated physical gates, all WIP/FG exchange vectors and each packaging ledger. Historic customer returns reverse original shipment/vector; actual additional rework is separately attributable, never new production. Check opening and closing separately accounted in-process stocks, including cooling-loop water, in both manufacturing and combined equations, with each actual uptake and input counted once.	ilcd-allocation-2010
`validate_species`	floor_make	Independently verify water states, mass/element and species evidence. Reject one-residual/two-unknown closure, integrated-volume double integration, guessed density, total-VOC/COD-to-species conversion or captured-plus-air double counting.
`validate_allocation`	all inventory rows	Verify the attributional context, subdivision and exclusive/virtual assignments, exchange-specific determining physical causality, then only genuine residual common-gate contemporaneous market value. No fixed shares, arbitrary mass/area/economic choice, automatic recovery credit or unsupported waste-method claim.	ilcd-allocation-2010
`validate_completeness`	all inventory rows	Check each actual atomic flow and destination, composition/provider limits, exact UUID property/unit chain, old failure records and missing data. Ordinary auxiliary/provider work is distinct from unresolved core route/terminal/method gaps; missing factory evidence blocks that dataset's completeness, not a fabricated scientific approval.
`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.
