Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Introduction
Short-chain chlorinated paraffins (SCCPs) (C -C ; chlorine content > 48 %) are listed by the Stockholm
10 13
Convention on Persistent Organic Pollutants.
[1]
In Europe, according to REGULATION (EU) 2019/1021 of the European Parliament and of the Council
of 20 June 2019 on persistent organic pollutants alkanes C -C , chloro [short-chain chlorinated
10 13
paraffins (SCCPs)] (CAS no. 85535-84-8) as constituents of articles are prohibited. Articles containing
SCCPs in concentrations lower than 0,15 % by weight are allowed.
Furthermore, it became industrial practice to restrict alkanes C -C , known as medium-chain
14 17
chlorinated paraffins (MCCPs) as well.
SCCPs and MCCPs are used as flame retardants in textiles, as plasticizers in polymers and as finishing
agents in leather. SCCPs and MCCPs are an issue for textile manufacturers and retailers due to their use
within fabrics, coated fabrics, plastisol prints, buttons, leather patches, etc.
The analysis of chlorinated paraffins is a great challenge. The technical compounds are always
complex mixtures of substances with different chain lengths and different chlorination degrees. Gas
chromatography (GC) separation of these mixtures show an overlapping part of chain length (between
short and middle chained) and of chlorination degrees, too. The responses of the different chlorination
degrees vary in a big range. This document describes a procedure to get comparable results for SCCPs
and MCCPs with a defined calibration standard of the most typical used mixtures (59 % chlorination
degree for SCCPs and 55 % chlorination degree for MCCPs) and using four ion traces for SCCPs and four
ion traces for MCCPs with gas chromatography negative ion chemical ionization mass spectrometry
(GC-NCI-MS).

1 Scope
This document specifies a chromatographic method to determine the amount of short-chain chlorinated
paraffins (SCCPs: C -C ) and middle-chain chlorinated paraffins (MCCPs: C -C ) in textile articles,
10 13 14 17
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).
