Curtains (including drapes) and interior blinds; curtain or bed valances

1. Scope and Applicability

This PCR applies to factory-gate foreground data packages for made-up textile curtains, drapes, textile interior blinds, curtain valances, and bed valances. The representative route converts purchased, finished woven polyester curtain fabric into a finished curtain by cutting, sewing and assembly, conditional in-house wet finishing, inspection, and packaging.

The PCR covers stock and custom-made products. It does not cover non-textile Venetian blinds, roller shutters, awnings, curtain rods or tracks, standalone textile fabric sold by length, upstream fibre/yarn/fabric production inside the foreground boundary, installation, use-stage cleaning, or end-of-life. Upstream production of every purchased product input remains connected through a qualifying dataset.

dq_product_specification	Reference product	Record all required qualifiers and link them to the lot-specific product specification.	Approved specification, bill of materials and inspection release
dq_temporal_coverage	Foreground activity data	Cover a representative continuous reporting period and identify shutdowns, trial runs, abnormal operations, and missing intervals.	Dated meter, production, stock and waste records
dq_meter_quality	Mass, electricity, water and steam records	Use calibrated equipment and retain calibration validity, reading resolution, conversion method, and treatment of shared meters.	Calibration certificates and meter logs
dq_completeness	Process inventory	Reconcile material, water and energy inputs with product, waste, wastewater, emissions where relevant, and stock changes; explain every material residual and excluded exchange.	Mass balance, water balance, energy reconciliation and exclusion log
dq_representativeness	Upstream datasets	Match geography, technology, material composition, recycled content, voltage, pressure and time period to the declared foreground input.	Dataset selection record and supplier specification

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_identity	Reference flow	Require the accepted state100 CPC 27130 product-flow UUID, Mass property UUID, 1 kg reference amount, and all required product qualifiers; the missing unit-group UUID remains a declared review item.	unsd-cpc-3-2025
validate_atomic_inventory	Every process inventory card	Require exactly one selected product, waste, or elementary exchange per card; reject collection labels, combined utilities, material selectors, and pending placeholders.	eu-textiles-bat-2022-2508
validate_bilingual_alignment	English and Chinese PCR files	Require identical ordered process_id, row_id, controlled token, source-id, and UUID sequences in both language renderings.	iso-14044-2006
validate_process_coverage	Foreground route	Require all required processes and require wet_finishing only when the reporting site performs the declared wet or thermal treatment.	us-census-naics-2022-314120; jrc-textiles-bref-2023
validate_foreground_amounts	Every inventory exchange	Require a linked collection protocol and reporting-period foreground record; do not accept AI-generated default values or ranges.	iso-tr-14049-2012
