1. Scope and Applicability
This PCR applies to finished woven fabric whose defining construction uses metal thread, metallized yarn, or both and that falls within CPC 3.0 subclass 27994. It supports gate-to-gate foreground data production from accepted yarn at the weaving site through inspection and saleable roll packaging. Optional preparation and wet-finishing operations are included only when performed within the reporting organization.
The PCR excludes metallized yarn sold as yarn (CPC 27993), ordinary woven fabrics classified by their non-metallic fibre, nonwovens, knitted fabrics, coated or impregnated fabrics classified elsewhere, made-up articles, and apparel. Upstream manufacture of metal thread, metallized yarn, chemicals, energy, and packaging is represented by linked supplier or background datasets rather than recreated inside the foreground boundary.

System boundary rules · 4
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
boundary_foreground_operations | foreground_system_boundary | Include yarn receipt and preparation, optional sizing, weaving, optional on-site pretreatment or finishing, inspection, roll making, packaging, on-site waste handling, and on-site wastewater handling up to the transfer point. | jrc-textiles-bref-2023, ec-pef-method-2021 |
boundary_purchased_inputs | purchased_product_inputs | Represent metal thread, metallized yarn, other yarn, chemicals, energy, water, and packaging with separate upstream datasets matched to the declared supply and geography. | ec-pef-method-2021 |
boundary_direct_releases | elementary_exchanges | Record direct releases to air and water only when measured or calculated from site records using a documented method; do not infer releases from purchased-input quantities. | jrc-textiles-bref-2023, ec-pef-method-2021 |
boundary_optional_operations | route_specific_operations | Mark sizing, wet pretreatment, dyeing, printing, coating, and finishing not applicable when absent; when present, disclose the exact operation and record each chemical, utility, waste, wastewater, and measured direct release separately. | jrc-textiles-bref-2023 |
Allocation rules · 3
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
allocation_avoid_by_subdivision | shared foreground operations | First subdivide meters, batches, production lines, and waste records so that fabric-specific inputs and outputs are directly assigned. | ec-pef-method-2021 |
allocation_physical_when_unavoidable | inseparable multi-product operations | When subdivision is not practicable, use a documented physical relation that reflects the causal use of the shared operation, such as machine time combined with measured power, treated mass, or wastewater volume. | ec-pef-method-2021 |
allocation_no_unjustified_credit | wastes and recoverable material | Record each waste destination and any revenue or recovered-product status; do not apply an avoided-burden credit inside the foreground inventory without the declared downstream method and consistent system model. | ec-pef-method-2021 |
Validation rules · 6
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
validate_reference_identity | reference product | Confirm the selected reference flow UUID, Product flow type, exact CPC 27994 classification, Mass property UUID, kg unit, and all required product qualifiers. | un-cpc-3-0-27994-2025 |
validate_atomic_inventory | process inventory | Reject combined or selector flows; every electricity supply, compressed-air supply, fuel, chemical, packaging component, waste, wastewater, and elementary release shall be a separate exchange with route applicability stated. | ec-pef-method-2021, jrc-textiles-bref-2023 |
validate_mass_balance | foreground batches | Reconcile input materials with saleable product, intermediate transfers, retained material, waste, and measured releases on the declared moisture basis; investigate and disclose unexplained differences. | ec-pef-method-2021 |
validate_route_completeness | optional operations | Confirm that sizing and each wet-finishing operation are either represented with their atomic inputs and outputs or explicitly marked not applicable. | jrc-textiles-bref-2023 |
validate_evidence | all reported values | Reject AI-generated amounts and unsupported default ranges; values shall come from foreground records or documented calculations, and every proxy or allocation shall be disclosed. | ec-pef-method-2021 |
validate_bilingual_alignment | PCR application | Confirm that English and Chinese machine identifiers, row order, UUIDs, controlled tokens, and normative rule ids are identical. | ec-pef-method-2021 |
Processes and inputs/outputs · 3
| Process ID | Process name | Input flows | Output flows |
