PFAS Restrictions Frequently Asked Questions
Short answers to the questions buyers ask most often about PFAS Restrictions.
What does it mean?
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.
What value should be specified?
Start from moving to non-detect targets and adjust for the end use of the garment. 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.
How is it tested?
EN 17681 tests after degradation. 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.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. 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.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. 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.
