AZO Dye Restrictions How to Read It on a Lab Report
Laboratory reports present AZO Dye Restrictions in a compact format. Knowing what each line means prevents misreading.
Definition reminder
ban on cleavable aromatic amines. 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.
Common report layout
The report states method EN 14362 determination, sample description, conditioning, and the measured result. 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.
Typical result
Values near below 30 ppm per amine usually indicate a conforming lot, assuming the fabric matches the sample submitted. 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.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. 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.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result. 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.
