Yarn of wool, containing 85% or more by weight of wool, not put up for retail sale

1. Scope and Applicability

This PCR applies to gate-to-gate foreground data packages for industrial wool yarn containing at least 85% wool by mass and leaving the yarn mill not put up for retail sale. It covers woollen and worsted routes from a declared prepared-wool starting condition through fibre preparation, carding or route-specific combing and drawing, spinning, winding, final conditioning, and industrial packing.

The data package shall distinguish woollen and worsted routes and shall state whether scoured wool, wool top, or another specifically identified prepared wool input is the starting condition. Raw-wool scouring, fibre dyeing, yarn dyeing, weaving, knitting, garment manufacture, use, and end-of-life are outside the default foreground boundary. When any excluded activity is performed at the reporting site, its process and every atomic exchange shall be added explicitly rather than hidden in a yarn-spinning aggregate.

This PCR does not cover yarn with less than 85% wool by mass, retail yarn packages, sewing thread, yarn made principally from other animal hair, or finished textile fabric. Secondary fibres are permitted only within the category threshold and shall be identified and inventoried as separate product inputs in the foreground data package.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_product_identity	reference yarn	Confirm at least 85% wool by mass, non-retail market state, and all required qualifiers for each released product family.	formulation or fibre test, product specification, release record
dq_mass_consistency	all material flows	Reconcile measured inputs, outputs, internal returns, stock change, and losses for each process and explain unresolved mass-balance differences.	batch mass balance and stock reconciliation
dq_metering	electricity, water, and channelled emissions	Use calibrated meters or documented allocation and monitoring methods; retain meter coverage and shared-load assumptions.	calibration certificate, meter map, monitoring report
dq_temporal_coverage	all foreground rows	Cover a representative reporting period, include seasonal or product-mix variation when material, and identify excluded downtime or abnormal operation.	production calendar and coverage assessment
dq_route_representation	woollen and worsted production	Keep route-specific records until any production-weighted aggregation is performed.	route-coded batch records and weighting worksheet
dq_source_traceability	all external and upstream data	Record supplier, geography, technology, time period, dataset version, and substitution rationale for every upstream dataset.	dataset registry and supplier evidence

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference_identity	reference flow	The final output UUID shall be 10c7de33-bef0-4310-98e7-734d8e2e4c9f, the flow type shall be Product flow, the CPC leaf shall be 26320, and the flow property shall be Mass.	unsd-cpc-3-2025
validate_wool_fraction	final yarn	Reject a package when the declared or tested wool mass fraction is below 85%.	unsd-cpc-3-2025
validate_reference_amount	final yarn	Confirm that the reference amount is 1 kg net accepted yarn at the declared conditioning state and excludes industrial packing mass.	iso-2060-1994
validate_required_qualifiers	final yarn	Reject an incomplete package when any required qualifier in the reference-flow definition is absent.	iso-1144-2016; iso-2060-1994
validate_required_processes	process map	Require fibre_preparation, spinning_and_winding, and conditioning_and_packing records, with explicit zero or not-applicable evidence only when a named operation or exchange is demonstrably absent.	bianco-et-al-2023-wool-lca
validate_atomic_inventory	every inventory row	Each exchange shall identify one product, waste, or elementary flow; combined carriers, combined packing materials, selector instructions, and plural catch-all flows are invalid.	eu-textiles-bat-2022
validate_flow_identity	UUID-bearing inventory rows	Confirm state code 100, the declared Product, Waste, or Elementary flow type, semantic name, reference property, and receiving compartment where applicable before use.
validate_unresolved_rows	rows without UUID	Require the exact row_id and selected single-flow name to match manifest unresolved_identity and prohibit publication until the identity gap is resolved or formally reviewed.
validate_mass_balance	each foreground process	Reconcile product and material inputs, product outputs, waste, internal return, stock change, and measured losses; report and justify residual imbalance.	eu-textiles-bat-2022
validate_allocation	multi-output process	Confirm subdivision priority and disclose any physical or economic allocation basis, data, and sensitivity result.	iso-14044-2006; bianco-et-al-2023-wool-lca

10. Published Dataset Profile

Field	Value
dataset_role	foreground production dataset for non-retail wool yarn manufacture
downstream_use	secondary_dataset; background_dataset after review and publication
