Quality and testing
A nominal number is not commercially useful unless method, conditioning, target and tolerance are defined together.

GSM, Width and Conditioning
GSM and width must be reported with conditioning, relaxation time and a clear usable-width definition.
40Colour Fastness: Wash, Crocking, Perspiration and Light
Fastness plans follow end use and shade depth; method and minimum grade belong in the technical file.
41Strength and Pilling Tests
Bursting strength and pilling appearance are interpreted against structure, GSM and garment-use intensity.
