PFAS Restrictions How to Read It on a Lab Report
Laboratory reports present PFAS Restrictions in a compact format. Knowing what each line means prevents misreading.
Definition reminder
chemical limits on perfluorinated compounds. Working figures for PFAS Restrictions normally sit around moving to non-detect targets in mainstream production. Note EN 17681 tests after degradation on the tech pack so nobody tests against an older revision.
Common report layout
The report states method EN 17681 tests after degradation, sample description, conditioning, and the measured result. Record elastane content alongside PFAS Restrictions, because blends shift the measured value. A result outside moving to non-detect targets usually points to process drift rather than to the fibre itself.
Typical result
Values near moving to non-detect targets usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for PFAS Restrictions lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN 17681 tests after degradation, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for PFAS Restrictions normally sit around moving to non-detect targets in mainstream production. Note EN 17681 tests after degradation 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 PFAS Restrictions, because blends shift the measured value. A result outside moving to non-detect targets usually points to process drift rather than to the fibre itself.
