Determining Initial Compliance Testing Obligations for Woven Fabric Orders
Verify woven fabric order compliance by mapping target market regulations to finish chemistry and requiring ISO 17025 test reports per dye lot.
CEN/TS 17681
Standard Definition
European standardization guidelines dictate how laboratories identify and measure specific synthetic organic compounds within consumer products. The technical specification known as CEN/TS 17681 establishes the reference methodology for detecting polyfluoroalkyl substances in apparel fabrics and trims. It applies to all textile components including yarn, face fabrics, linings, and functional membranes.
Chemical Target
Liquid chromatography coupled with mass spectrometry forms the basis for isolating these persistent substances. Within the scope of CEN/TS 17681, the extraction covers perfluorooctane sulfonate and perfluorooctanoic acid alongside other restricted fluorinated chemicals. Identifying these agents at trace levels prevents contaminated shipments from entering markets with strict environmental bans.
Testing Protocol
Extracted samples undergo pressurized liquid processing or ultrasonic treatment using organic solvents to release bound finishes from the fiber matrix. This phase of CEN/TS 17681 requires precise temperature regulation during the solvent cycle to ensure high recovery rates. The laboratory performs multiple extraction cycles to guarantee that all extractable residues are captured in the test vial before chromatographic separation.
This thorough sequence eliminates false negatives and secures reproducible results across different laboratory runs.
Validation Limit
Calibration curves established with certified reference standards determine the final concentration of each target compound. Laboratories reporting under CEN/TS 17681 must achieve detection thresholds well below the regulatory limit of one microgram per square meter of fabric. This stringent reporting ensures that waterproof coatings and stain treatments comply with commercial trade covenants.
