Description (English):

This document specifies a chromatographic method to determine the amount of short-chain chlorinated paraffins (SCCPs: C10-C13) and middle-chain chlorinated paraffins (MCCPs: C14-C17) in textile articles, especially in polymer of the coated fabrics, prints made of polymer and buttons made of polymer (e.g. polyvinylchloride) by means of solvent extraction and gas chromatography negative ion chemical ionization mass spectrometry (GC-NCI-MS).

Abstract

Overview

EN ISO 22818:2021 specifies a chromatographic method for the determination of short-chain chlorinated paraffins (SCCP, C10–C13) and middle-chain chlorinated paraffins (MCCP, C14–C17) in textile products. The method targets a range of textile matrices - especially polymers in coated fabrics, polymer-based prints and polymer buttons (e.g., PVC) - using solvent extraction followed by gas chromatography negative ion chemical ionization mass spectrometry (GC‑NCI‑MS). The standard provides a reproducible procedure and defined calibration approach for comparable SCCP and MCCP results.

Key Topics and Requirements

Scope and targets: SCCPs (C10–C13) and MCCPs (C14–C17) in textile articles.
Sample preparation: Solvent extraction (toluene indicated in the method) and sulfuric acid clean-up to remove interferences prior to analysis.
Analytical technique: GC‑NCI‑MS with a defined calibration standard; the method uses multiple ion traces (four for SCCP and four for MCCP) to address complex mixtures.
Calibration: Calibration uses typical chlorination degrees of technical mixtures (SCCP ~59% Cl; MCCP ~55% Cl) to improve comparability.
Expression of results and QA: Procedures for calibration, evaluation, recovery determination of internal standards, interference checks and reporting of results are included.
Regulatory context: SCCPs are listed under the Stockholm Convention and are restricted in the EU (REGULATION (EU) 2019/1021); the standard supports compliance testing (articles with SCCP
