T-shirts, singlets and other vests, knitted or crocheted

1. Scope and Applicability

This PCR governs production of foreground data packages for finished knitted or crocheted T-shirts, singlets, undershirts, tank tops, and comparable vests. It applies to consumer and professional garments of any declared fibre composition, size range, colour, and finish when the garment is ready for sale or shipment at the manufacturing gate.

The foreground boundary begins with finished knitted or crocheted fabric, thread, trims, accessories, packaging, and other purchased inputs delivered to the garment-manufacturing system. It covers material receipt and preparation, cutting, sewing and assembly, conditional garment-stage wet processing or finishing, quality control, packaging, manufacturing waste, and conditional on-site wastewater treatment. Fibre production, yarn production, knitting, fabric-stage dyeing and finishing, purchased energy production, and packaging manufacture are represented by traceable upstream datasets unless they occur under the declared foreground operator's control.

The PCR does not by itself represent distribution, retail, consumer use and care, reuse, or end-of-life. A downstream lifecycle model may add those stages. Fabric sold as fabric, woven garments, hosiery, sweaters and pullovers, babies' garments, other knitted apparel, leather or fur apparel, and non-textile garments are outside this canonical product boundary.

validate_allocation	Shared processes	Fail if allocation bypasses subdivision without justification, lacks a defensible physical relationship, or uses economic allocation without reporting-period values and sensitivity analysis.	epd-international-pcr-2024-03-apparel; iso-14044-2006
validate_upstream_links	Purchased inputs and services	Fail if main fabric, other main materials, packaging, energy, transport, or off-site treatment is treated as burden-free or linked to an unassessed generic/proxy dataset.	epd-international-pcr-2024-03-apparel; ec-pef-method-2021-2279
validate_data_quality_disclosure	Published foreground dataset	Fail if the time period, geography, technology, supplier-specific/generic/proxy status, measurement methods, allocation, cut-offs, uncertainty, and unresolved identity references are not disclosed.	epd-international-pcr-2024-03-apparel; iso-14048-2002

10. Published Dataset Profile

Field	Value
dataset_role	Foreground manufacturing dataset for finished knitted or crocheted T-shirts, singlets, and other vests
downstream_use	secondary_dataset; background_dataset for product systems that require the garment-manufacturing stage; source for downstream process and lifecyclemodel projections
allowed_use	Garment-manufacturing LCI, supplier-specific or representative production modelling, hotspot analysis, and connection to separately modelled upstream fabric and downstream distribution/use/end-of-life stages
excluded_use	Claiming a complete cradle-to-grave apparel result without connected upstream and downstream stages; comparison across garments with different function, lifetime, performance, composition, or care scenario without functional equivalence; use as a fabric-production dataset
required_metadata	PCR id and version state; product and flow identity; composition; construction; size basis; net unit mass; colour/finish; included route; site and geography; reporting period; reference UUIDs; upstream dataset identities; allocation; cut-offs; data sources
required_quality_disclosure	specific, selected-generic, and proxy data shares; measurement and sampling methods; temporal, geographical, and technological representativeness; mass and energy closure; waste routes; assumptions; uncertainty; sensitivity; unresolved UUIDs and range-evidence gaps
update_trigger	Change in product construction, composition, supplier route, technology, site, energy supply, wet-processing recipe, waste treatment, allocation, or data period that materially changes an inventory amount or any declared environmental result; correct errors and refresh stale upstream datasets
