BS EN ISO 23702-1:2023 Leather. Per- and polyfluoroalkyl substances Determination of non-volatile compounds by extraction method using liquid chromatography

Introducing the BS EN ISO 23702-1:2023, a comprehensive standard that provides a detailed guide on the determination of non-volatile compounds in leather using an extraction method with liquid chromatography. This standard is a must-have for professionals in the leather industry, environmental scientists, and quality control personnel who are keen on ensuring the safety and quality of leather products.

Key Features

The BS EN ISO 23702-1:2023 standard is a 34-page document that provides a step-by-step guide on how to accurately determine the presence of per- and polyfluoroalkyl substances (PFAS) in leather. PFAS are a group of man-made chemicals that have been in use since the 1940s. They are used in a wide range of consumer products, including leather goods, because of their ability to resist heat, water, and oil. However, they are also known to persist in the environment and in the human body, leading to potential health risks.

This standard provides a reliable method for the extraction and determination of these non-volatile compounds, ensuring that leather products are safe for use and meet regulatory requirements. It is an essential tool for anyone involved in the production, testing, and regulation of leather goods.

DESCRIPTION

BS EN ISO 23702-1:2023


This standard BS EN ISO 23702-1:2023 Leather. Per- and polyfluoroalkyl substances is classified in these ICS categories:
  • 59.140.30 Leather and furs
This document specifies a test method for detection and quantification of extractable non-volatile per- and polyfluoroalkyl substances (PFAS) in leather and coated leather by solvent extraction and liquid chromatography coupled with mass spectrometry. This document, taking into account the three-dimensional distribution of the fibres within leather, makes the evaluation of the PFAS with respect to the mass. PFAS substances categories and applications are listed in Annex A, Table A.1. Classes of PFAS regulated compounds listed in Annex B, Table B.1, include acids, telomers, sulfonates and sulphonamide alcohols. Classes of other non-regulated compounds that can be determined by this document are listed in Annex C, Table C.1. NOTE 1        By applying the method specified in this document, the concentration of free fluorotelomer alcohols (FTOH) in a sample cannot be correctly quantified if perfluoropolymers that release FTOH due to transesterification with the extraction solvent methanol are present in the sample. NOTE 2        Some regulations (e.g. Reference [4]) also restrict perfluoropolymers having a linear or branched perfluoroheptyl group with the moiety (C7F15)C as one of the structural elements that can degrade to PFOA, e.g. polymers containing 2-perfluorooctylethanol (8:2 FTOH, CAS Registry Number® 678-39-7) bonded as esters. To determine whether these perfluoropolymers are intentionally present, it could be necessary to introduce an alkaline hydrolysis method to remove the 8:2 FTOH side-chain from the polymer. In addition, other FTOH, e.g. 6:2 FTOH or 10:2 FTOH, will be released from relevant perfluoropolymers by alkaline hydrolysis.
