Leather - Per- and polyfluoroalkyl substances - Part 1: Determination of non-volatile compounds by extraction method using liquid chromatography (ISO 23702-1:2023)

This document specifies a test method for detection and quantification of extractable neutral, ionic, long, medium and short chain perfluorinated and poly-fluorinated substances in leather and coated leather.
This document, taking into account the three-dimensional distribution of the fibres within leather, makes the evaluation of the perfluorinated and poly-fluorinated substances with respect to the mass.
Classes of regulated compounds listed in Annex A, Table A.1, include acids, telomers, sulfonates and sulphonamide alcohols. Classes of other non-regulated compounds that can be determined by this document are defined in Annex B, Table B.1.

Leder - Per- und Polyfluoralkylsubstanzen - Teil 1: Bestimmung von nichtflüchtigen Verbindungen durch Extraktion mit Flüssigchromatographie (ISO 23702-1:2023)

Dieses Dokument legt ein Prüfverfahren zum Nachweis und zur quantitativen Bestimmung von extrahierbaren nichtflüchtigen Per- und Polyfluoralkylsubstanzen (PFAS) in Leder und beschichtetem Leder mittels Lösemittelextraktion und Flüssigkeitschromatographie in Verbindung mit Massenspektrometrie fest.
Unter Berücksichtigung der dreidimensionalen Faserverteilung innerhalb des Leders bewertet dieses Dokument die PFAS im Hinblick auf die Masse.
PFAS-Kategorie und -Anwendungen sind in Anhang A, Tabelle A.1 aufgeführt. Die Klassen der regulierten PFAS-Verbindungen, die in Anhang B, Tabelle B.1, aufgeführt sind, schließen Säuren, Telomere, Sulfonate und Sulfonamidalkohole ein. Die Klassen anderer, nicht regulierter Verbindungen, die nach diesem Dokument bestimmt werden können, sind in Anhang C, Tabelle C.1, aufgeführt.
ANMERKUNG 1   Bei Anwendung des in diesem Dokument festgelegten Verfahrens kann die Konzentration freier Fluortelomeralkohole (FTOH) in einer Probe nicht korrekt quantifiziert werden, wenn Perfluorpolymere, die FTOH durch Umesterung mit dem Extraktionslösemittel Methanol freisetzen, in der Probe vorhanden sind.
ANMERKUNG 2   Einige Vorschriften (z. B. Verweisung [4]) beschränken auch Perfluorpolymere mit einer linearen oder verzweigten Perfluorheptylgruppe mit dem Bestandteil (C7F15)C als einem der Strukturelemente, die zu PFOA abgebaut werden können, z. B. Polymere, die als Ester gebundenes 2 Perfluoroctylethanol (8:2 FTOH, CAS-Registernummer®  678 39 7) enthalten. Um festzustellen, ob die Anwesenheit dieser Perfluorpolymere beabsichtigt ist, könnte die Aufnahme eines alkalischen Hydrolyseverfahrens zur Entfernung der 8:2 FTOH-Seitenkette des Polymers erforderlich sein. Darüber hinaus werden andere FTOH, z. B. 6:2 FTOH oder 10:2 FTOH, durch alkalische Hydrolyse aus entsprechenden Perfluorpolymeren freigesetzt [3].
WARNUNG — Die Anwendung dieses Dokuments schließt gefährliche Substanzen ein. Es gibt nicht vor, alle mit seiner Anwendung verbundenen Sicherheits- oder Umweltprobleme zu behandeln. Es liegt in der Verantwortung der Anwender dieses Dokuments, vor dessen Anwendung geeignete Maßnahmen zu ergreifen, um die Sicherheit und Gesundheit von Personal sicherzustellen und die dafür maßgebenden Anforderungen zu erfüllen.

Cuir - Substances perfluoroalkylées et polyfluoroalkylées - Partie 1: Détermination des composés non volatils par une méthode d’extraction utilisant la chromatographie en phase liquide (ISO 23702-1:2023)

Le présent document spécifie une méthode d'essai de détection et de quantification de substances perfluorées et polyfluorées neutres, ioniques, à chaîne longue, moyenne et courte, extractibles dans le cuir et le cuir verni.
Le présent document, tenant compte de la distribution tridimensionnelle des fibres dans le cuir, réalise l'évaluation des substances perfluorées et polyfluorées par rapport à la masse.
Les classes de composés réglementés répertoriés dans le Tableau A.1 de l'Annexe A comprennent des acides, des télomères, des sulfonates et des alcools sulfonamides. Les classes d'autres composés non réglementés qui peuvent être déterminés par le présent document sont définies dans le Tableau B.1 de l'Annexe B.

Usnje - Per- in polifluoroalkil snovi - 1. del: Določevanje nehlapnih spojin z metodo ekstrakcije z uporabo tekoče kromatografije (ISO 23702-1:2023)

Ta dokument določa preskusno metodo za odkrivanje in kvantifikacijo izločljivih nevtralnih, ionskih, dolgoverižnih, srednjeverižnih in kratkoverižnih perfluoriranih in polifluoriranih snovi v usnju in premazanem usnju.
Ta dokument, upoštevajoč tridimenzionalno porazdelitev vlaken v usnju, vrednoti perfluorirane in polifluorirane snovi glede na maso.
Razredi predpisanih spojin, navedenih v preglednici A.1 dodatka A, vključujejo kisline, telomerje, sulfonate in sulfonamid alkohole. Razredi drugih nepredpisanih spojin, ki jih je mogoče določiti s tem dokumentom, so opredeljeni v preglednici B.1 dodatka B.
