| Predmet normy: | This document specifies a test method, including the degradation of certain side-chain fluorinated polymers during the extraction with simultaneous alkaline hydrolysis, and using liquid chromatography (LC) and tandem mass spectrometry (MS/MS) for identification and quantification of certain per- and polyfluoroalkyl substances (PFAS). The document is applicable to all materials of textile products. Table 2 indicates a list of target PFAS which can be analysed with this document. PFAS of Table 2 marked with the footnote e) and footnote f) undergo alkaline hydrolysis and only their per- or polyfluorinated degradation products such as PFOA or n:2 fluorotelomer alcohols (n:2 FTOHs, n = 4, 6, 8, 10) can be determined. Through the methods outlined in the informative Annex E and Annex F, free n:2 FTOHs, PFOA and non-polymeric PFAS of Table 2 marked with the footnote e) and footnote f), that are not stable to alkaline hydrolysis, can be identified and quantified. Certain side-chain fluorinated polymers release ... |
