Full title and description

STB DIN EN ISO 22818:2021-06 — Textiles — Determination of short‑chain chlorinated paraffins (SCCP: C10–C13) and middle‑chain chlorinated paraffins (MCCP: C14–C17) in textile products from different matrices by solvent extraction and gas chromatography with negative‑ion chemical‑ionization mass spectrometry (GC‑NCI‑MS). This entry describes the German (DIN/EN) version published June 2021, which is the national adoption of ISO 22818:2021.

Abstract

This standard specifies a chromatographic analytical method for the quantification of SCCP and MCCP residues in textile articles and polymeric components (for example coated fabrics, polymer prints and polymer buttons such as PVC). The approach uses solvent extraction, an acid clean‑up step and analysis by GC‑NCI‑MS with defined calibration and QA/QC procedures to produce reproducible, comparable results.

Scope

The standard applies to the determination and quantification of short‑chain (C10–C13) and middle‑chain (C14–C17) chlorinated paraffins in textile items and relevant polymeric components. It is intended for use on a range of textile matrices where SCCP/MCCP may be present as additives or residues, with a defined sample preparation (solvent extraction), clean‑up and GC‑NCI‑MS measurement procedure to enable consistent reporting between laboratories. Use includes regulatory compliance testing (e.g., POPs/REACH context) and product safety verification.

Key topics and requirements

• Analytes defined: SCCP (C10–C13) and MCCP (C14–C17) with reporting conventions for summed homologues.
• Sample preparation: solvent extraction (appropriate organic solvent), drying/concentration and sulfuric‑acid clean‑up to remove interferences.
• Analytical technique: gas chromatography coupled with negative‑ion chemical‑ionization mass spectrometry (GC‑NCI‑MS) with specified ion traces and calibration practice.
• Calibration and QA/QC: use of calibration mixtures that emulate technical chlorinated‑paraffin mixtures, internal standards, method blanks, recoveries and limits of detection/quantification.
• Applicability: validated for coated fabrics, plastisol/polymer prints and polymeric trims (e.g., buttons), with guidance on sample mass, extraction conditions and result expression (mg/kg or other agreed units).

Typical use and users

Primary users are accredited analytical and contract testing laboratories, textile manufacturers and finishers, component suppliers (e.g., for polymeric buttons/prints), compliance teams (product safety, regulatory affairs), brand/regulator auditors and research groups studying persistent organic pollutants in textiles. Typical applications include routine compliance testing for POPs and restricted substances, supplier verification, incoming goods testing and failure‑investigation analyses.

Related standards

Closely related documents and reference points include the original ISO 22818:2021 and the EN adoption (EN ISO 22818:2021). Complementary or sector‑specific methods for SCCP/MCCP analysis exist (for plastics and electrical/electronic components) such as draft/prEN IEC 62321‑14 (GC‑NCI‑MS method for SCCP/MCCP in plastics), and other contemporary textile chemical test standards covering different restricted substances (for example, emerging EN/CEN methods for PFAS analysis). Regulatory instruments and international conventions (Stockholm Convention; EU POPs/REACH regulations) are also relevant context for applying ISO 22818.

FAQ

Q: What is this standard?

A: ISO 22818:2021 (adopted as DIN EN ISO 22818:2021‑06) is an analytical testing standard that specifies a laboratory method to determine short‑chain and middle‑chain chlorinated paraffins in textile articles using solvent extraction and GC‑NCI‑MS.

Q: What does it cover?

A: It covers scope, required reagents and apparatus, specimen preparation, extraction and clean‑up, instrumental GC‑NCI‑MS parameters, calibration and reporting conventions for SCCP (C10–C13) and MCCP (C14–C17) in a variety of textile matrices (notably polymer coatings, polymer prints and polymer buttons). The standard provides method performance expectations and quality control guidance.

Q: Who typically uses it?

A: Accredited analytical laboratories, textile and trim manufacturers, product safety and compliance teams, regulators and auditors use this method for routine testing, supplier checks and regulatory compliance verification where SCCP/MCCP restrictions apply.

Q: Is it current or superseded?

A: The DIN/EN adoption published in June 2021 is the current national adoption of ISO 22818:2021. Users should check national standards bodies for any subsequent amendments or newer adoptions; the standard is subject to periodic review under ISO procedures.

Q: Is it part of a series?

A: ISO 22818 is a stand‑alone analytical method for SCCP/MCCP in textiles but is conceptually related to other analytical standards for chemicals in materials (for example parts of the IEC 62321 series for electrotechnical products and other EN/ISO methods addressing different restricted substances in textiles). Laboratories commonly use it alongside other substance‑specific test standards when assessing product chemical safety.

Q: What are the key keywords?

A: SCCP, MCCP, chlorinated paraffins, textile testing, GC‑NCI‑MS, solvent extraction, coated fabrics, polymer prints, PVC buttons.
