This document specifies a test method (using gas chromatography, GC) for detection and quantification of selected extractable perfluorinated and polyfluorinated substances in textile materials (fibres, yarns, fabrics) and coated fabrics. NOTE CEN/TR 16741 defines which materials are applicable to this determination. A test method (using liquid chromatography, LC) for detection and quantification of selected extractable perfluorinated and polyfluorinated substances is specified in prEN 17681-1. Classes of regulated compounds are listed in Table 2. Classes of other non-regulated compounds that can be determined by this document are defined in Annex C, Table C.1. This document is also applicable for further PFAS substances provided that the method is validated with the additional compounds.
