The method describes how to determine MPs in the field of textile processing and applications, and allows their classification by particle dimension and shape as well as by type of polymer

This part of the standard specifies a test method (using gas chromatography, GC) for detection and quantification of al l extractable perfluorinated and polyfluorinated v ol at i le substances in textile products (for example, in fabrics treated with fluoro-chemical finishes and in coated fabrics). Classes of volatile and non volatile (Part 1 of this Standard) compounds (regulated and of concern) in Table 1 include acids, salt acids, esters, amides, telomers, sulfonates, sulfonamides and sulfonamidalcohols.

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 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 prEN 17681-2. 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.

<sec id="sec_1.1"><label>1.1</label><p>This document specifies a procedure for determining the lowest temperature at which rubber-or plastics-coated fabrics will not exhibit fractures or coating cracks when subjected to specific impact conditions.</p></sec><sec id="sec_1.2"><label>1.2</label><p>Rubber-or plastics-coated fabrics are used in many applications involving low-temperature flexing with or without impact. Data obtained by this method may be used to predict the behaviour of these coated fabrics at low temperatures only in the applications in which the conditions of deformation are similar to those specified in the method.</p></sec>
