7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_scope	all inventory attribution	Use this rule only for an explicitly chosen attributional inventory where allocation is necessary. First isolate dedicated shell/assembly/test/services; then physical or virtual subdivision directly assigns recipe materials and fitted components to the actual configuration. Internal cullet and reused packaging are transfers rather than automatic coproducts or avoided-production credits.	ilcd-allocation-2010
allocation_causality	each remaining exchange	For each still shared exchange identify the determining physical causal relationship and justify evidence: actual batch energy/temperature duty, press/test cycle demand, air-cooling work, heat capacity, occupied storage volume/area and duration or limiting transported mass/volume and distance as appropriate. Different exchanges can require different determinants. A list of possible mass/area/time/price keys or one blanket factor is not a decision; failed/idle/cleanup burdens remain assigned to the responsible production/service cohort.	ilcd-allocation-2010
allocation_residual	genuine residual shared process burdens	Only after documented subdivision and exchange-specific causality are exhausted allocate the genuine residual by actual same-period market values of real coproducts at the same common process gate and actual condition/quality/moisture/bulk state. Remove additional packaging/transport/conditioning from downstream prices transparently. Do not invent fixed fractions, saleability, negative waste prices as a credit or substitution. Unavailable defensible residual prices/causality remain an uncertainty requiring review. Keep all unscaled physical package, product, waste and asset ledgers independent of this burden partition.	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.

Measure species independently from total indicators and keep origins separately. Retain raw actual species mass and uncertainty; reference normalize_exchange once for unit result.	kg	continuous or justified mode-resolved sampling	full campaign with failed intervals	same raw physical control volume	per 1 kg reference flow	species analysis; flow calibration; moisture; receiving compartment; independent closure
cp_residues	manufacture	each separate waste and destination	waste removal and treatment record	exchange_id; net_wet_mass; dry_solid; free_water; bound_water; composition; attached_material; destination; treatment; transfer_note; internal_return; inherited_vector	Weigh each real separate waste, retained attachments, moisture and receiving route.

No assumed lifetime or count-to-mass coefficient. Keep physical assets unscaled; asset_service prepares current contribution without unit normalization; reference normalize_exchange once.	item; kg; m3	each installation change and campaign closure	opening history through remaining service disclosure	Each actual equipment and installed-fluid gate	per 1 kg reference flow	asset register; maintenance log; installed-fluid count; service evidence

Do not erase added water or losses or treat gross return mass as an original-delivery reversal. Keep raw increments; use original cohort Q in the sole normalize_exchange result per reference flow. Before assigning a returned unit to accepted stock, verify the governing documented permission and actual post-work tests/disposition; otherwise retain reject/waste status. Track each new and removed part and water/state change separately; never infer restored electrical/mechanical fitness from a brochure or visual repair.	actual native row unit	each service and stock change	declared original-cohort service horizon	actual warehouse/packing/handling gates	per 1 kg reference flow	cohort linkage; service meters; dispatch/return documents; FG bridge ; governing permission and post-work test/disposition records

Count-to-mass uses real package weighing, not a brochure or guessed pallet weight. package_balance reconciles raw gross mass without economic scaling; reference one normalize_exchange result only for attributed unit inventory. When actual water uptake/loss or material changes occur beyond already counted package/article or repair receipts/removals, add independently measured X_in and X_out on the respective incoming/outgoing sides. Name every actual added/removed material or water phase as a specific atomic exchange before dataset completion. These extra terms are deduplicated ONLY against other incoming/outgoing flow terms, never against closing stocks. Retained water/repair material stays in BOTH the real inflow and full closing physical mass; the same applies to actual outgoing transfers and opening stocks. Preserve gross quantities and each inherited vector separately, without inventing repair/uptake, forcing dry wood, shrinking mass by a burden share or buying an embodied component twice.	kg	each packing receipt dispatch return repair and closure	full service horizon with opening history	all empty attached and reusable package pools	per 1 kg reference flow	BOM; package weigh slips; moisture; return/repair record; stock census

The aggregation_rule column states the final reporting basis only; collection_method and raw_fields retain unnormalised raw quantities. Every aggregation references the single calculation below without division at collection.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
raw_conversion	all inventory rows	Convert each raw quantity to its row native extensive unit once; integrate only a measured rate over its interval. kWh×3.6 gives MJ. For gas/liquid mass use independent density at the actual measured state; fuel heat uses measured LHV/HHV/composition. Separate physical carrier and thermal accounts. No normalization.	raw_value; raw_unit; state; independent_density; calorific_basis; cp_utilities	R_j	jrc-glass-bref-2013; ilcd-allocation-2010
asset_service	refractory; mould; melter; press; thermal_station; curing_station; filter_felt; hydraulic_fluid	Separate actual physical stock/addition/removal records from service contribution. Assign directly consumed repairs/material to the responsible cohort; partition equipment upstream vectors only by documented actual service and remaining-service evidence with exchange-specific causality. Installed-fluid and carried repair vectors are stock-corrected once; no fixed lifespan or full-asset-per-kg factor.	physical_asset_ledger; upstream_vector; service_driver; cp_assets	R_j	ilcd-allocation-2010; jrc-glass-bref-2013
attribute_inventory	all inventory rows	For each exchange retain R_j and genuine dedicated/virtual-subdivision assignment, then justified physical causality and only genuine residual allocation from section7. A_j = Bopen_j + attributed_current_j - Bclose_j for manufacturing raw/WIP and unassigned non-WIP stores; released closing FG is excluded from Bclose_j. For service A_j is actual incremental vector tied to its original cohort plus its legitimate service stocks. Already-net values are not corrected twice. Gross physical ledgers are independent.	R_j; dedicated_assignment; causal_evidence; residual_price_evidence; Bopen_j; Bclose_j; inherited_vector	A_j	ilcd-allocation-2010
package_balance	all packaging rows	Opening empty + opening attached WIP + opening attached FG + opening reusable + purchases + supplier-included receipt + external returns received + new repairs = mutually exclusive closing stocks + gross shipments out + separate external returns sent + waste + actual losses. Reconcile each material independently; internal reuse cancels and this equation never divides by Q or scales by economic share. When actual water uptake/loss or material changes occur beyond already counted package/article or repair receipts/removals, add independently measured X_in and X_out on the respective incoming/outgoing sides. Name every actual added/removed material or water phase as a specific atomic exchange before dataset completion. These extra terms are deduplicated ONLY against other incoming/outgoing flow terms, never against closing stocks. Retained water/repair material stays in BOTH the real inflow and full closing physical mass; the same applies to actual outgoing transfers and opening stocks. Preserve gross quantities and each inherited vector separately, without inventing repair/uptake, forcing dry wood, shrinking mass by a burden share or buying an embodied component twice.	opening_stocks; incoming; closing_stocks; gross_outgoing; waste; actual_losses; cp_pack	package_balance_residual	lagranja-insulators-2019; ilcd-allocation-2010
normalize_exchange	all inventory rows	q_j = A_j / Q	A_j; Q; cp_release	q_j	ilcd-allocation-2010
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

Execute normalize_exchange only when Q>0 and exactly once. The reference output1kg represents the same measured Q; every card and aggregation refers to that result and never redivides. Service uses its original released cohort Q over the stated actual observation horizon. Q=0 keeps real raw burden and cause with no unit result. Gross physical conservation remains unscaled and independent of burden attribution.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	every adopted flow and provider	Confirm the complete product and every card native condition with actual BOM/SDS/drawing/provider evidence. A generic family name does not prove composition or manufacturing route; unresolved auxiliaries stay specific and need compatible identity before dataset finalization.	native evidence; BOM; supplier agreement
dq_coverage	full campaign and service horizons	No failed/idle/cleanup/rework/stock exchange is dropped; disclose completeness, unknowns, extrapolation and uncertainty by stage/cohort. Future factory quantity requirements are not measured data.	all protocols; operating logs; independent balances
dq_reactions	glass and cement and species	Provide independent recipe/assay, phase/reaction extent and actual species evidence. Separate carbonate loss, cement hydration/free water, atmospheric water and physical stock vectors; a closure residual is not two missing measurements.	laboratory phase/species evidence; physical and elemental checks
dq_method	source use and attribution	Maintain complete original source context, limitations and contrary examples. Industrial sources support technology only; ILCD supports the stated attributional hierarchy. No brochure number is a factory default. Independent scientific and translation review remain pending.	source locators; allocation decision; uncertainty disclosure

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_terminal	reference product and first_release	Verify complete glass/cap/forged-pin/aluminous-cement/stainless-clip BOM, hot cure and all required tests at first release. A pure glass disc, porcelain insulator, unfinished assembly, RTV variant or string fails this boundary even if an electrical-insulator name is similar.	lagranja-insulators-2019; sediver-hvac-2017
validate_basis	all inventory rows	Reference and finished row are1kg of the same complete net assembled product. Verify unique Q from actual release weighing; closing released FG is already in Q. Check every raw→converted→attributed→single A_j/Q link and original-cohort service denominator. Q=0 retains burdens with no unit result.	ilcd-allocation-2010
validate_native	all flow and unit bindings	Recheck every native CAS/form/route/grade/geography/compartment/property restriction in the consuming card and actual supplier choice. Exact property→unit-group→reference-unit support is required; no latest-version substitution, secondary-density inference or Item(s)-to-kg guess. Unsupported core identity makes guidance unavailable; auxiliaries remain explicit gaps until resolved.	lagranja-insulators-2019; jrc-glass-bref-2013
validate_balance	manufacture FG services and combined control volume	Independently reconcile actual wet physical and relevant elemental balances, reaction/species evidence, WIP/history vectors, complete-assembly and dismantled-waste exclusivity, installed assets/fluids, actual heat-carrier water returns and every package stock/movement cell. Economic allocation changes burden attribution, not gross physical masses; one residual cannot establish multiple unknowns.	jrc-glass-bref-2013; ilcd-allocation-2010
validate_completeness	final dataset and uncertainty	All actual flows and missing measurements must be accounted, including conditional inputs and extra service repairs/species. A not-applicable finding requires evidence of absence; unknowns cannot pass as zero. Schema/projection/finite measurement success does not establish scientific approval, translation approval, classification acceptance or publication.	jrc-glass-bref-2013; ilcd-allocation-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.
