AZO Dye Restrictions Specification Targets for Buyers
Setting AZO Dye Restrictions correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place AZO Dye Restrictions next to composition and weight so all three are quoted as one package. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: below 30 ppm per amine. Record elastane content alongside AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
Tolerances that work
Allow a small tolerance rather than a fixed number, since normal process variation exists in every lot. Keeping reference values for AZO Dye Restrictions lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN 14362 determination, since both affect the reading.
Verification method
Confirm with EN 14362 determination and keep the report against the bulk record. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination on the tech pack so nobody tests against an older revision.
Commercial note
Tightening beyond practical need raises cost without improving garment life, so set the tightest target only where it protects the customer. Record elastane content alongside AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
