Plastics - Poly(vinyl chloride) - Determination of residual vinyl chloride monomer - Gas-chromatographic method (ISO 6401:2008)
ISO 6401:2008 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.
A "dry method", suitable for PVC resins but not compounded materials, is widely used within the industry for in-house determinations. A separate International Standard based on this methodology is under development.
Kunststoffe - Polyvinylchlorid - Bestimmung des Restgehaltes an Vinylchlorid-Monomer - Gaschromatographisches Verfahren (ISO 6401:2008)
Die vorliegende Internationale Norm legt ein Verfahren zur Bestimmung des Vinylchlorid-Monomers in Vinylchlorid-Homopolymeren und Copolymeren sowie Compound-Materialien fest. Das Verfahren beruht auf dem Lösen der Probe und anschließender Headspace-Gaschromatographie. Dabei können Vinylchlorid-Konzentrationen im Bereich von 0,1 mg/kg bis 3,0 mg/kg bestimmt werden.
Ein für PVC-Harze jedoch nicht für Compound-Materialien geeignetes „Trockenverfahren“ findet in der Industrie für betriebsinterne Bestimmungen häufig Anwendung. Eine getrennte Internationale Norm zu dieser Verfahrensweise wird derzeit erarbeitet.
Plastiques - Poly(chlorure de vinyle) - Détermination du chlorure de vinyle monomère résiduel - Méthode par chromatographie en phase gazeuse (ISO 6401:2008)
L'ISO 6401:2008 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 entre 0,1 mg/kg et 3,0 mg/kg.
Pour les déterminations en interne, le secteur de l'industrie a pour habitude d'utiliser une «méthode sèche», adaptée aux résines PVC mais pas aux matériaux composés. Une autre Norme internationale s'appuyant sur cette méthodologie est en cours d'élaboration.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 6401 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-chemical
properties.
This second edition cancels and replaces the first edition (ISO 6401:1985), which has been technically revised.
