Angol cím

Textiles and textile products. Organic fluorine. Part 1: Determination of non-volatile compounds by extraction method using liquid chromatography

Alkalmazási terület

This document specifies a test method (using liquid chromatography, LC) for detection and quantification of selected extractable perfluorinated and polyfluorinated substances in textile materials (fibres, yarns, fabrics) and coated fabrics. NOTE 1 CEN/TR 16741 defines which materials are applicable to this determination. A test method (using gas chromatography, GC) for detection and quantification of selected extractable perfluorinated and polyfluorinated substances is specified in EN 17681-2. NOTE 2 Both this document and EN 17681-2 are needed for the determination and totalization of the PFOA related substances. 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. NOTE 3 Commission Delegated Regulation (EU) 2020/784 amending Annex I to the POP Regulation (EU) 2019/1021 as regards the listing of perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds defines among other that “’…PFOA-related compounds’ means the following: … any substances that degrade to PFOA, including any substances (including salts and polymers) having a linear or branched perfluoroheptyl group with the moiety (C7F15)C as one of the structural elements.” To determine whether these are intentionally present it could be necessary to introduce an alkaline hydrolysis method to remove the side-chain from the polymer. According to Commission Regulation (EU) 2021/1297 [7], this applies similarly to C9-C14 PFCAs-related compounds. A future revision of this document will address this aspect.
