It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. Unknown Textile Identification & Evidence Record Permanent record: Source page: - Primary job: Choose materials - Area: Materials - For: Both - Location or jurisdiction: Global - Access: Open access - Format: Stitch Authority - Source type: Stitch Authority - Linked page reviewed: 2026-07-16 - Next review due: 2027-07-16 ### Best for Investigating an unknown textile without using flame, smoke, odor, or residue as composition, flammability, care, safety, or compliance proof ### What the source establishes The guide cites current AATCC qualitative and quantitative fibre-analysis methods, the published ISO 1833-1 quantitative-analysis principles, ASTM's withdrawn D276 status and reinstatement work item, current FTC U.S. textile-label guidance, and current CPSC clothing-textile flammability guidance. ### Know before using The record does not identify a submitted textile, provide a home burn procedure, turn an observation into a fibre or blend result, choose a laboratory method, establish flammability or market compliance, validate a care instruction, or replace qualified laboratory, textile, conservation, safety, compliance, and legal review. ## 2. Pattern Grading & Size-Run Validation Record Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Apparel brands - Location or jurisdiction: Global - Access: Open access - Format: Stitch Authority - Source type: Stitch Authority - Linked page reviewed: 2026-07-27 - Next review due: 2027-07-27 ### Best for Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence ### What the source establishes The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. ### Know before using The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. ## Next checks 1. Remove any route whose audience, jurisdiction, access, or scope does not match the job. 2. Open the permanent record and source page for every remaining route. 3. Recheck facts that can change after the listed review date. 4. Verify project-specific capability, terms, test evidence, and legal requirements with the responsible source or provider. 5. Record the reason for the final choice outside Stitch Authority.
