# Carbon-foamed closed-cell glass insulation blocks and slabs

## 1. Scope and Applicability

This PCR covers one semantic product and material manufacturing need: unfaced closed-cell cellular-glass insulation rectangular blocks/slabs made by melting recycled glass and minerals, cooling and milling the glass with carbon black, filling moulds, thermal cellulation, controlled annealing, cutting/grinding and first quality release. It is a narrower subset of CPC3.0:37117, not the entire mixed classification leaf. Reuse existing compatible glass melting, reference-flow, allocation and data-quality principles, while this powder-reaction/cell-retention/annealing terminal cannot be represented by float-stock sheets, mechanically edge-polished annealed sheets, Danner tube or thermal safety-glass quenching. `foamglas-route`; `foamglas-t3plus-epd-2026`; `foamglas-t3plus-pds-2025`; `bau-foam-glass-pcr-2025`

The complete publisher sources form a transparent technical synthesis without claiming one SKU, factory, recipe or contemporary order. The actual2026 EPD uses1m3 and2023 two-site measured density; this PCR declares1kg net actual product and requires measured geometry/density for transparent volume/service conversion. Historical brochure>66%, current website50% and source ingredient fractions/temperatures are context-specific, not universal recipe, reaction, energy, yield or performance defaults. BAU includes a glycerine/waterglass granulate example and aggregate standard; neither replaces this carbon-black closed-cell block route. Methodology below is attributional and factory production guidance, not EPD programme certification. `foamglas-route`; `foamglas-t3plus-epd-2026`; `foamglas-process-brochure`; `foamglas-t3plus-pds-2025`; `bau-foam-glass-pcr-2025`; `ilcd-attributional-2010`

It supplies no strength, density, thermal conductivity or conformity approval.

## 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 | Use1kg net actual equilibrated product at first quality release after cutting and required tests. Q is unique first-released mass of the selected cohort. Exclude removable packaging and surface contamination; retain real closed-cell gas and carbon in product mass. |
| volume_conversion | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Mass basis is primary. For requested m3, measure the same actual configuration external volume and net mass under the same state; state measured bulk density and express transparent conversion. Nominal95 or source2023 measured91kg/m3 is not this site density. Do not infer density from an unrelated flow secondary property. |
| single_normalization | all inventory rows | Row-specific physical property | Row-specific physical unit | Keep raw collection undivided. convert_raw and attribute_raw form A_j before normalize_exchange performs A_j/Q once. Inventory and collection basis is per1kg reference flow; cards and aggregation only reference this single result. Q=0 keeps raw burdens and no unit result. Q is measured in kg of reference product; A_j retains its own exchange property and numerator unit. The common denominator yields row unit/kg reference product, including MJ/kg for electricity and m3/kg for natural gas, and never converts every numerator to Mass/kg. |

## 5. System Boundary

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| boundary_route | manufacture | Include actual virgin minerals and externally supplied compatible cullet with upstream burdens and inbound transport through batch mixing, melting, cooled-glass milling with carbon black, filling steel moulds, thermal cellulation, controlled annealing, rectangular cutting/grinding, inspection and first quality release. Keep each real raw ingredient, fuel, electricity, water, auxiliary and outlet atomic. Purchased finished foam-glass packing alone cannot satisfy this manufacturing scope. | `foamglas-route`; `foamglas-t3plus-epd-2026`; `foamglas-process-brochure` |
| boundary_reference_gate | manufacture and service | Q is the calibrated net mass in kg of unique first-released uncoated closed-cell blocks after required tests, at declared equilibrium condition. Retained cell gases and residual carbon belong to actual product mass; removable packaging does not. Failed lots and pre-release destructive samples do not enter Q; their real burdens remain. Newly released closing FG is already included in Q. Delivery, reinspection, repair, return and later shipment do not create production. The reference row is first_release only. | `foamglas-t3plus-epd-2026`; `foamglas-t3plus-pds-2025`; `bau-foam-glass-pcr-2025` |
| boundary_stocks | all inventory rows | Retain full representative period, start/stop, zero-output, idle, cleaning, failures and rework. Measure opening/closing raw materials, melt, powder and block WIP and non-WIP charges of oil, cooling water and other actual fluids separately. Each stock has its own physical quantity and exchange-specific inherited burden vector. Keep any included mould/tool/equipment asset physical stock separate from its documented remaining and consumed service vectors, with no invented life or repeated whole-asset procurement. Manufacture closing contains only unreleased raw/WIP and unassigned charge/service inventory, not already first-released FG. Raw meter consumption already corrected for charge change is not adjusted again. Internal scrap returns and interstage transfers cancel in consolidation and never become new purchases. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025`; `ilcd-attributional-2010` |
| boundary_fg_services | service | Keep physical receipts from first release, opening/closing FG by cohort, gross dispatch, external returns received, original-delivery reversals, standalone external returns sent, breakage and real repair additions/removals, moisture and gas changes. Returning or reworked FG retains its original release and inherited vector. Service burdens are assigned to the original served release cohort using its original Q, with actual incremental repair only; older FG and reversals cannot be transferred to unrelated current Q. Manufacturing transfers and service receipts cancel when consolidated. Already performed original-cohort service remains in its A_j even when goods stay in closing FG. No net-delivery denominator is substituted. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025`; `ilcd-attributional-2010` |
| boundary_species | manufacture and service | Keep full physical mass and C/S/N/O/H and other relevant elements independently from reaction-species and phase evidence. Include actual gross wet air inlet/outlet with each gas separately, product-retained gas/carbon, offcuts, dust and treatment outlets. Do not fit two unknowns with one residual, infer a gas reaction yield from cell density, turn NOx/COD/VOC into named chemical mass, or treat cell gas as a new external purchase. Actual additional raw materials, scrubber reagents, filter consumables, repair parts and newly detected species require separate cards and collection before completion; no other-flow bundle or unsupported zero. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025` |
| boundary_supply | all inventory rows | Every whole purchased preparation, mineral, article or supplied mixture is one purchase of the complete delivery state; assay, carrier water and active substance are constituent subaccounts, never additional purchases of the same material. Removable transport packaging has its own physical receipt ledger; identify supplier-included burden and do not purchase that embodied burden twice. Actual on-site formulation uses each bought ingredient with real mixing energy, loss and water. Match all native UUID restrictions and provider geography, route, form, medium and reference property; unidentified aux UUIDs do not remove exchanges. Disclose upstream recovery/end-of-waste and burden handover rather than assuming recycled input is free or crediting offcuts. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025`; `ilcd-attributional-2010` |
| boundary_water_heat | manufacture and service | Distinguish supplied water, carrier/free/structural/reaction water, wet sludge and actual atmospheric humidity and condensate origin. Use independently measured substance-specific density and thermal state; a liquid/gas integrated volume is already an amount, whereas only a true rate is integrated over time. Actual external heat-exchange water/condensate returns are Product exchanges at measured temperature/enthalpy under the supplier water-energy convention. Do not invent a steam system, boiler, condensate yield, exported heat or automatic energy credit from a recovery arrow. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025` |
| boundary_exclusions | dataset applicability | Exclude coated/faced/bituminous boards, aggregate/gravel, fibre wool, open-cell acoustic foam, cold-bonded glass agglomerates, insulating glazing units, pressed solid glass bricks, mirrors, tempering and installed systems. Carbonate-only, glycerine/waterglass or SiC foaming is not this carbon-black route. Ordinary surface trimming remains included; actual changed core chemistry/forming requires new applicability assessment. The source EPD cradle-to-grave modules and BAU programme declarations do not turn this manufacturing PCR into a complete EPD or authorize module-D credit. | `foamglas-route`; `foamglas-t3plus-epd-2026`; `foamglas-t3plus-pds-2025`; `bau-foam-glass-pcr-2025` |

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Actual separate whole mineral/salt/carbon-black supplies and compatible recovered cullet with documented recovery state and upstream burden handover at receiving gate; full on-site glass and cellular-block manufacture |
| starting_condition_role | Upstream purchased material inputs with inherited burdens plus actual full foreground manufacture; not finished-block repacking |
| product_classification_scope | CPC3.0:37117; narrower carbon-black foamed closed-cell uncoated slab/block |
| recursive_input_rule | Internal scrap retains original burden vector and cancels. External same-category returned or recycled blocks require actual physical state and recovery processing with documented burden handover; never silently zero-burden virgin replacement |
| upstream_dataset_requirement | Match each complete supplied material/utility/article and external recovery/transport/treatment route state geography and reference property; preserve per-exchange history |
| disclosure | Declare full raw-to-first-release route plus distinct post-release service scope and original cohort denominator. No manufacturing cutoff, installed lifetime or automatic EPD/moduleD claim |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| manufacture | Integrated batch melting milling carbon foaming annealing cutting and quality release | required | Full actual raw-to-terminal route with all failure and stock records | foreground | first_release |
| service | Post-release packaging warehousing handling and dispatch | required | Actual recorded services and gross physical movements assigned to original release cohort; no new production | foreground | per1kg original reference cohort; no added Q |

### Process: Integrated manufacture (`manufacture`)

Within manufacture, source-stage meters separate batching/melting, cooling/milling, mould filling/foaming/annealing and cutting/release. These are one integrated inventory control volume: interstage material and internal heat transfers are documented and cancelled, not bought twice. Additional real utility, consumable, reaction species or treatment branches must be decomposed before dataset completion.

Conditional identity is 95% sodium carbonate from natural-alkali processing at chemical plant, CAS497-19-8. Record the complete supplied salt once; assay, hydrate/free water and impurities are subaccounts. The carboxylic-acid classification is an isolated taxonomy defect; CAS/name/comment identify carbonate. A different purity or synthetic/recycled route requires another verified identity; no95% recipe requirement.

###### Iron oxide glass ingredient (`ferric_oxide`)

Mineral-derived ferric oxide/hematite, CAS1309-37-1, production mix at plant; native comment is mined/processed hematite, not an emulsion-polymerized adhesive. Match actual Fe(III) oxide form and assay; FeO, Fe3O4, iron ore of unknown composition and a fixed synthetic pigment route need separate identities.

- Selected flow: Ferric oxide `27dcbd61-ba08-45f3-a87b-2a87b5fb2423`

###### Carbon-black foaming reagent (`carbon_black`)

Commercial solid carbon-black particle aggregates, CAS1333-86-4; native synonyms cover acetylene/channel/furnace/lamp/thermal black without selecting one production route. Match actual grade, aggregate structure, particle size, ash, sulfur and moisture with supplier evidence. Graphite-family taxonomy is isolated; no graphite, dye Direct Black38, SiC or cement-soot mixture is substituted. Count the entire supplied reagent once and retain residual carbon and cell-gas subaccounts.

###### Manufacturing furnace fuel (`natural_gas`)

Actual compressed/pipeline-delivered gaseous natural gas meeting the applicable gas standard at consumption, CAS74-82-8 native methane-family identity. Do not substitute pure methane, LNG, crude gas or a particular Jiangsu CHP composition. Volume is the native reference: retain actual meter temperature/pressure/compressibility and supplier base state; verify provider compatibility. The native secondary Mass meanValue1 is not a physical density. Measure actual composition and LHV independently for mass/energy balances; no default gas or boiler.

###### First quality-released uncoated cellular-glass block (`first_release`)

Generic formed-and-finished glass Product identity, Mass/kg, no native fixed grade, route, CAS, geography, particle specification or performance data. The37199 taxonomy does not establish or veto this independently evidenced closed-cell slab boundary.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| allocate_subdivide | each shared exchange | For attributional inventory first assign dedicated measured burdens and use physical or virtual subdivision with actual equipment time, metered process or documented engineering model. Preserve real common losses and failed/idle burdens; do not remove them by naming a dedicated step. | `ilcd-attributional-2010` |
| allocate_causality | each residual exchange | For remaining shared exchange j, test a determining physical causal relationship to actual product functions and changed output amounts. Different density, milling fineness, foaming recipe, dwell time and thermal condition can change the driver; plant-wide mass allocation in the cited EPD is case practice, not proof of that causality. Do not arbitrarily choose mass, volume, energy or economic shares. | `ilcd-attributional-2010`; `foamglas-t3plus-epd-2026` |
| allocate_residual_value | genuinely residual multifunctional common process | Only if subdivision and determining physical causality cannot resolve genuine remaining multifunctionality use contemporaneous actual-state market values at the same common process gate, with quantities, currencies, moisture/quality and time aligned. Remove different downstream finishing, transport and sales service before comparing values. Record justification and sensitivity, never a fixed ratio. Saleability of scrap alone does not create a co-product or automatic substitution credit. | `ilcd-attributional-2010` |
| allocate_cohort | all stocks and service | Carry every exchange burden with original material/release cohort through WIP, FG, charges, returns and real repair. Allocate shared service to the actual served cohorts, retain original delivery reverse links and original Q, and keep a separate gross physical ledger. External recycled input treatment and returned packaging follow explicit burden handover and repeated-service records; internal reuse is neither another purchase nor negative credit. | `ilcd-attributional-2010`; `bau-foam-glass-pcr-2025` |
| 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.

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| cp_mfg | manufacture | raw materials utilities and auxiliaries | foreground production records | supplier and whole delivery state; batch recipe; assay and moisture; each raw material mass; original meters and units; actual gas composition state density and LHV; electric supply voltage geography; campaign start stop idle failure rework; raw and non-WIP charge stocks; inherited exchange vectors; inbound transport per material and mode | Calibrated scales and meters with receipt/recipe reconciliation and direct equipment logs over the entire real route. Record whole purchased preparations once; validate actual operator flow sheet and individual real fuel/material names. Transport has actual mass distance and mode with separate real fuel/emissions if operated on site, or matched transport-service dataset outside this unit inventory. Retain undivided raw totals. convert_raw and attribute_raw precede the single normalize_exchange result per 1 kg reference flow; collection performs no division. | kg; MJ; m3 at declared gas state; original meter units | each batch and meter interval | complete representative period with all zero-output campaigns | declared site and equipment boundary through first release | per 1 kg reference flow | calibration; invoices; actual recipe; supplier specification; metering boundaries; stock vectors |
| cp_balance | manufacture | physical mass phase species and emission records | measurements and laboratory records | each inlet and outlet species; original volume or rate; time; temperature pressure humidity and compressibility; actual exhaust moisture and O2; retained cell gas and residual carbon; glass oxide and sulfate sulfide speciation; wet and dry waste; dissolved and suspended content; real wastewater receiving medium; actual returned water temperature enthalpy; opening closing melt powder block WIP and fluid charge; vector history | Independent calibrated mass/volume sampling and actual gas speciation across one consistent control volume. Separate stack from fugitive releases and each receiving medium. Distinguish measured species from analytical indicators; determine gas reactions, bound/free water and phase movement with independent records rather than residual fitting. Validate physical mass and elements before applying burden allocation. Retain undivided original physical/species observations. Use physical_gates separately; only attributed exchange totals enter normalize_exchange once per 1 kg reference flow. | kg by species; original m3 or rate; measured state and enthalpy | each campaign stock boundary and representative species sample | same manufacture period and stock history | manufacturing physical control volume and actual treatment outlets | per 1 kg reference flow | sampling reports; detection limits; gas calibration; independent elemental assays; moisture and flow-state records |
| cp_release | manufacture | first_release | quality release and net weighing | unique release identifier; product configuration; composition and carbon route; actual dimensions and density; closed-cell evidence; thermal conductivity and compressive test method results; applicable standard; anneal cutting and test record; net equilibrated mass; tare and surface condition; first-release time; destructive test loss; closing FG membership | Weigh actual uncoated accepted blocks using calibrated scales at recorded equilibrium condition; remove removable packaging and contamination, retain actual cell gases/residual carbon. Link each unique release to tests, lot, geometry and failures. Measure mass and external volume for the same configuration independently rather than importing nominal catalogue density. Collect raw Q in kg only; release_denominator defines Q and first_release represents 1 kg reference flow. No normalization of raw release records during collection. | kg; measured dimensions and test units | each block or traceable weighed lot at first release | same selected first-release cohort | first release after all required manufacturing quality tests | per 1 kg reference flow | scale calibration; unique release register; test results; tare; traceable configuration and equilibrium state |
| cp_service | service | packaging FG returns and services | cohort stock movement and meter records | original release cohort and Q; original delivery and reversal; opening closing FG; gross dispatch; returns received and sent; breakage; actual repair additions removals; each packaging empty attached WIP attached FG reusable stocks; purchases supplier-included receipts external returned receipts gross outgoing separate returns sent waste; wood paper moisture; actual repair board nail mass and origin; full article versus constituent; inherited exchange vector; raw energy water and fluid charges | Weigh each real article/configuration and moisture condition and reconcile mutually exclusive physical stocks and movements. Keep complete FG and packaging gross ledgers even for old cohorts; link return/reversal to original delivery, real repairs and inherited burden. Meter actual storage/handling/packing and cleaning services. Add real repair materials and gas/water changes as individual rows before claiming complete coverage, without inventing them. Collect undivided raw quantities. Reconcile packaging_ledger and physical_gates before attribute_raw; use normalize_exchange once per 1 kg reference flow of the original served cohort and its original Q. Older-cohort service remains separate from unrelated current manufacturing results. | kg; MJ; original article counts and moisture | each movement and matched service meter interval | selected release cohort and its original stock history | post-release physical and service gate | per 1 kg reference flow | stock and dispatch records; return links; calibrated article weights; actual repair evidence; inherited vectors; service meter coverage |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| convert_raw | all inventory rows | Convert each actual raw record to its row unit and declared state before stock/burden attribution. Electricity MJ = kWh * 3.6. Integrate only actual mass/volume rates over measured time; cumulative meter differences and already integrated volumes are amounts and receive no second time multiplier. Use independent substance-specific density at measured state for mass/volume, and actual article mass per configuration for counts. Gas native secondary factors never replace measured density or actual LHV. | raw readings; unit factors; measured density and state; article configuration | converted raw totals | `bau-foam-glass-pcr-2025` |
| attribute_raw | all inventory rows | Distinguish physical movement quantities from burden/consumption numerators before attribution. For each manufacture exchange j reconcile opening unreleased raw/WIP and unassigned installed/service vector + actual converted additions = corresponding closing unreleased/unassigned vector + first-release transfer B_j^Q + evidenced assignments to other real cohorts/functions. Manufacturing burden A_j is B_j^Q after documented subdivision and any genuine residual allocation; it includes all newly first-released FG even when held at closing, never subtracting that FG vector. Ordinary waste, offcuts, failed lots and destructive tests retain their caused manufacturing and handling/treatment burdens: physical export or sale alone cannot deduct their inherited burden as transferred elsewhere or create a credit. Any assignment elsewhere needs traced distinct cohort/function and the applicable allocation or burden-handover decision. FG history separately reconciles opening FG vector + B_j^Q + actual returns at original dispatch vector + actual service increments = closing FG vector + gross dispatch vector + other traced removals/destinations. Original manufacture is restored on return for tracing, not added again. Service burden A_j includes each actually performed increment for the original served cohort using original Q, even if serviced goods remain in closing FG; correct only disjoint unconsumed/unassigned service or charge inventories. For explicit purchase/receipt, gross dispatch, return and waste movement cards A_j is the converted actual physical movement; maintain burden/consumption vectors separately, without netting unused stock against a gross receipt. Each B retains that exchange numerator/unit, never stock kg substituted for every burden; never correct already stock-adjusted consumption twice. Internal transfers cancel once in the consolidated account. | converted raw totals; exchange-specific stock vectors; cohort and return links; allocation records | A_j attributable raw exchange totals | `ilcd-attributional-2010` |
| release_denominator | first_release | Q = sum of measured net mass in kg of uniquely first-released blocks/slabs of the selected product cohort after required quality tests. Use recorded equilibrium state and remove packaging and surface contamination; keep true retained cell gas and residual carbon. Pre-release failures/test destruction are excluded; their burdens remain. First-released closing FG is already in Q. Dispatch, return, repair and retesting add no Q. | cp_release; unique release registry; net mass; quality tests | Q in kg | `foamglas-t3plus-epd-2026`; `foamglas-t3plus-pds-2025`; `bau-foam-glass-pcr-2025` |
| normalize_exchange | all inventory rows | q_j = A_j / Q for Q > 0. Execute this single division after convert_raw and attribute_raw; q_j is the exchange per 1 kg reference flow for the same release cohort. For Q = 0 retain A_j and raw burdens without a unit result. Flow cards and protocol aggregation only reference this same computed result and never divide again. | A_j; Q; convert_raw; attribute_raw; cp_release | q_j per 1 kg reference flow | `ilcd-attributional-2010`; `bau-foam-glass-pcr-2025` |
| physical_gates | all inventory rows | Manufacturing: opening raw + opening WIP + opening non-WIP charges + external supplied materials + measured gross inlet gas species = closing raw + closing WIP + closing charges + Q + each physical exported waste + each measured outlet species + each actual product return. FG service: opening FG + first-release internal receipt + external returned FG + actual repair additions + measured physical uptake = closing FG + gross dispatch + standalone external FG return + scrap + repair removals + measured gas/water loss. Apply consistent wet/phase/thermal bases and independently measured relevant elements and chemical species; one residual is not two measurements. Consolidation cancels manufacture-to-service receipt. Manufacture closing excludes already first-released FG; the combined gate cancels internal Q and first-release vectors, not completed manufacturing or performed service. Gross carrier-gas observations serve physical closure; report actual environmental withdrawal or new process release with independent origin, reaction, retention, phase and native-flow convention evidence. Equal chemical names do not make resource-input and emission UUIDs interchangeable or establish a characterization offset. Do not add closing FG to production Q or report retained cell gas as external emission. | cp_mfg; cp_balance; cp_release; cp_service; independent species and phase measurements | separate and consolidated physical and elemental gates | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025` |
| packaging_ledger | all inventory rows | For EACH actual packaging article: opening empty + opening attached WIP + opening attached FG + opening reusable + new purchases + supplier-included receipts + external returns received = closing empty + closing attached WIP + closing attached FG + closing reusable + with gross physical shipments + standalone external returns sent + waste. All categories are mutually exclusive and each receipt counted once. Add real article water uptake/loss and actual repair-part additions/removals as separate measured terms when needed; keep complete pallet and repair components distinct without counting constituents twice. Internal reuse cancels; burden allocation and inherited exchange vectors remain separate. Packaging never enters Q or automatic co-product credit. | cp_service; article stocks; physical receipts and dispatch; moisture; real repairs; inherited vectors | each article physical ledger and burden reconciliation | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025`; `ilcd-attributional-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 |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| dq_identity | all inventory rows | Every row retains full native restrictions and actual matched provider/state; UUID is not a default amount, conformity certificate or proof of recipe. Unresolved auxiliaries remain single named exchanges. | Native direct records; provider specification; actual product tests |
| dq_period | all inventory rows | Retain complete raw meter coverage with zero-output failures start/stop and idle. Separate representative production data from legacy supplier examples and manufacturer marketing claims. | Raw readings; calibrated logs; cohort register |
| dq_species | all physical gates | Measure phase and molecular species independently of total mass/element balance. Cell-retained CO2 and residual carbon, sulfate/sulfide, actual free/reaction/structural water and exhaust O2 require genuine evidence. Keep indicators and molecular species distinct. | Independent analytical speciation; phase records; uncertainty and detection limits |
| dq_stocks | all stocks and service | Each raw/WIP/FG/charge/packaging stock has physical quantity and inherited vector per exchange. Preserve original release and delivery reversals; actual rework additions and moisture/species changes are not silently ignored. | Opening closing measurements; cohort links; vector history; real repair documents |
| dq_unknown | dataset completion | Unknown, absent, measured zero and below detection are different states. Missing actual core route, terminal or unresolved causal relationship stays a true hold. Provider matching, unbound auxiliaries and future site activity quantities remain explicit ordinary production gaps; no fabricated default or scientific approval. | Gap register; applicability decisions; raw observations |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| validate_terminal | reference product and route | Verify actual unfaced closed-cell carbon-foamed glass slab/block from the entire manufacturing route and actual release tests, dimensions, density and surface condition. Generic Glass (formed & finished) does not certify closed cells, building suitability, thermal conductivity, compressive strength or any legal compliance. Do not apply the entire CPC leaf to one product or replace carbon-black foaming with a different foaming agent. | `foamglas-route`; `foamglas-t3plus-epd-2026`; `foamglas-t3plus-pds-2025`; `bau-foam-glass-pcr-2025` |
| validate_identity | each inventory row | Check whole direct native basename, all synonyms/comments, CAS, grade, route, geography, form/particle structure, medium, type, every property and exact reference chain before UUID adoption. Retain each restriction in the description and actual provider evidence. Isolated taxonomy defects are disclosed separately from physical consistency; hard CAS/route/media contradictions are not waived. | `bau-foam-glass-pcr-2025` |
| validate_physical | manufacturing service and consolidated gates | Close gross manufacturing and FG-service physical gates independently and then cancel matching internal transfers. Include all actual species, water phases, cell-retained gas/carbon, dust and moisture using independent measured composition and phase evidence. Keep physical mass/element conservation independent of burden allocation. Unknowns and imbalance retain explicit uncertainty/hold; never fit two unknown reactions by one residual. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025` |
| validate_normalization | all raw quantities | Convert units/state first, reconcile stock and historical vectors and allocate second, execute normalize_exchange once as A_j/Q last. Collection retains undivided raw data; cards and aggregation reference that same result and never divide it again. Q=0 retains all real raw burdens without a unit result. Manufacturing production Q, gross shipments and net deliveries are distinct. Require the attribute_raw distinction between first-release manufacture, already performed service, unassigned inventories and physical movement; neither closing FG nor ordinary waste export automatically removes caused burdens. | `ilcd-attributional-2010`; `bau-foam-glass-pcr-2025` |
| validate_packaging | each packaging article | Require complete mutually exclusive opening/closing empty, WIP-attached, FG-attached and reusable stocks; new purchases; supplier-included physical receipts; external returns received; packaging with gross physical shipment; standalone external returns sent and waste. Count only one physical receipt per article. Internal reuse cancels and does not change Q. Identify real wood/paper moisture, nails, replacement boards and other actual repair parts separately from complete pallet purchases; do not invent repairs. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025`; `ilcd-attributional-2010` |
| validate_coverage | dataset completion | Actual unknown core manufacturing/terminal or causal burden relationship prevents a completed dataset claim. Preserve failed retrievals, source edition differences, mechanical applicability mismatches and unknown/absent/zero/below-detection separately. Ordinary future site measurements, provider matching and auxiliary UUID gaps remain explicit data-production requirements; technical projection/measurement checks do not establish scientific, translation, mapping or publication approval. | `foamglas-t3plus-epd-2026`; `bau-foam-glass-pcr-2025`; `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. |  |
