Rubber thread and cord, textile covered; textile yarn and strip, impregnated or covered with rubber or plastics

1. Scope and Applicability

This PCR applies to factory-gate production of CPC 27992 products made by either mechanically covering rubber thread or cord with textile yarn, or impregnating or covering textile yarn or strip with a rubber or plastic compound. The foreground boundary starts with receipt of the declared substrate, covering yarn or coating compound, process utilities, and packaging and ends with packaged saleable product at the producing factory gate.

The methodology covers route-specific covering, winding, impregnation or coating, drying or curing when used, inspection, off-spec handling, and packing. Upstream production of rubber, textile fibres and yarn, polymer compounds, electricity, fuels, water, and packaging remains represented by linked product-system datasets. The user must select the route that physically produced the declared product and must not combine the two routes into a synthetic average unless a documented production-weighted portfolio dataset is the stated study object.

calc_energy_normalization	electricity and natural gas	Convert recorded utility quantities to the declared unit without combining electricity and fuel; fuel energy equals delivered amount multiplied by the documented heating value.	electricity meter; fuel delivery; heating value; output mass	kWh electricity per kg and MJ fuel per kg	eu-textiles-bat-2022
calc_allocation	shared foreground totals	Allocated amount equals reconciled shared total multiplied by the selected product's causal-driver quantity divided by the sum of the same driver for all products sharing the total.	shared total; product driver; total driver	allocated foreground amount	iso-14044-2006; eu-pef-2021-2279

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	reference product and material inputs	Declare route, substrate form and fibre family, formulation identifier, cover construction or coating pickup, physical specification, and packaging state.	product specification; formulation or recipe; lot traveller; packaging bill of materials
dq_temporal	all foreground records	Use records from one coherent reporting period that captures representative operation and disclose shutdowns, trials, and abnormal batches.	reporting-period definition; production log; exception register
dq_completeness	all atomic exchanges	Reconcile meters, stocks, product, each waste stream, and relevant named releases; no combined material, utility, waste, or emission placeholder is allowed.	inventory checklist; meter and stock reconciliation; waste and emission register
dq_mass_balance	each selected route	Investigate material-balance residuals and explain moisture, volatile loss, sampling, stock, or measurement effects without inventing a balancing exchange.	signed mass-balance worksheet; measurement uncertainty record
dq_chemicals	coating route	Maintain a formulation-level chemical inventory with identity, quantity, function, solids or solvent content, and batch linkage.	approved recipe; safety and technical data sheets; batch issue records
dq_tests	saleable output	Record the applicable physical or mechanical specification and test history, including rubber-thread processing history where relevant and yarn linear-density method where relevant.	certificate of analysis; ISO 20058, ISO 2321, or ISO 2060 test record as applicable
dq_uuid	every implemented exchange	Resolve each implemented atomic exchange to one exact Tiangong flow identity with compatible type, property, and unit; unresolved candidate rows remain review findings and must not be assigned a near-neighbour UUID.	hybrid-search evidence; independent state100 direct-read evidence; review log

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_flow	dataset reference	Require the exact CPC 27992 Product flow UUID, Mass property UUID, kg reference unit, 1 kg net amount, and all required qualifiers.	un-cpc-v3-27992; iso-14044-2006
validate_route	process selection	Require at least one applicable route and reject a single-lot dataset that mixes covering and coating exchanges without a documented production-weighted portfolio definition.	iso-14044-2006
validate_atomic_inventory	inventory structure	Require one physically or chemically specific exchange per row and reject collection flows, selector instructions, combined utilities, combined wastes, and combined emissions.	eu-pef-2021-2279
validate_mass_balance	route material balance	Require input, product, waste, moisture or solids, and measured release reconciliation and a documented explanation of residuals.	eu-textiles-bat-2022
validate_formulation	coating route	Require the actual substrate and compound formulation, dry solids, coating pickup or cover fraction, and applicability decisions for every conditional material and substance.	eu-textiles-bat-2022
validate_utilities	electricity, fuel, and water	Require separate quantities, compatible units, meter or allocation evidence, heating-value basis for fuel, and a water balance where process water is used.	eu-textiles-bat-2022
validate_emissions_waste	wastes and releases	Require each waste identity and destination separately and report ammonia or toluene only when formulation relevance and a measured or approved calculation are documented.	eu-textiles-bat-2022
validate_sources_protocols	foreground evidence	Require every foreground-record row to link to a declared collection protocol and require every method claim to cite an allowed source.	iso-14044-2006; eu-pef-2021-2279
validate_uuid_evidence	Tiangong identities	Reject unverified or semantically broader, narrower, or proxy UUIDs; report each unresolved row by row_id until hybrid and state100 direct evidence both confirm an exact identity.	un-cpc-v3-27992
