Plastics - Poly(vinyl chloride) - Determination of residual vinyl chloride monomer using gas-chromatographic method (ISO 6401:2022)
This document specifies a method for the determination of vinyl chloride monomer in homopolymer and copolymer resins of vinyl chloride and compounded materials. The method is based on sample dissolution and headspace gas chromatography. Concentrations of vinyl chloride in the range 0,1 mg/kg to 3,0 mg/kg can be determined.

Plastiques - Poly(chlorure de vinyle) - Détermination du chlorure de vinyle monomère résiduel par la méthode de chromatographie en phase gazeuse (ISO 6401:2022)
Le présent document spécifie une méthode de détermination de la teneur en chlorure de vinyle monomère dans les résines d’homopolymères et de copolymères de chlorure de vinyle et matériaux composés. Cette méthode repose sur la dissolution de l’échantillon et sur la chromatographie en phase gazeuse à espace de tête. La concentration en chlorure de vinyle peut être déterminée dans la plage de 0,1 mg/kg à 3,0 mg/kg.
Polimerni materiali - Polivinilklorid - Določevanje preostanka vinilklorida s plinsko kromatografsko metodo (ISO 6401:2022)
ISO 6401:2008 določa metodo za določevanje monomera vinilklorida v homopolimernih in kopolimernih smolah vinilklorida in mešanih materialih. Metoda temelji na raztapljanju vzorca in plinski kromatografiji v prostoru. Določiti je mogoče koncentracije vinil klorida od 0,1 mg/kg do 3,0 mg/kg.
»Suha metoda«, ki je primerna za PVC-smole, ne pa za mešane materiale, se pogosto uporablja v industriji za interno uporabo. V pripravi je ločen mednarodni standard, ki temelji na tej metodologiji.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-
chemical properties, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 6401:2008), which has been technically
revised.
The main changes are as follows:
— a reference for the density of N,N'-dimethylacetamide has been added;
— the condition for storing vinyl chloride standard solutions has been specified more precisely;
— the formula for the expression of the vinyl chloride content in relation to the amount of resin has
been corrected;
— the test report has been extended.
Any feedback or questions on this document should be directed to the user’s national standards body. A
