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 SO, also take part in the work. isO collaborates closely with the International Electrotechnical Commission (lEC)onallmattersofelectrotechnicalstandardization. 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. International Standard ISO 13741-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials, in close collaboration with ISO/TC 45, Rubber and rubber products. IsO 13741 consists of the following parts, under the generaltitle Plastics/rubber - Polymer dispersions and rubber latices (natural and synthetic) - Determination of residual monomers and other organic components by capillary-column gas chromatography: Part 1: Direct liquid injection method Part 2: Headspace method @ISO1998 All rights reserved.

Former standards for measurement of residual volatiles based on distillation linked with titration cannot cope with such exigences. by gas chromatography, of residual monomers and other organic components in polymer dispersions and latices. This standard provides a method that is in line with present-day requirements for analytical methods and is intended for use instead of iSO 2008:1987, Rubber latex, styrene- butadiene Determination of volatile unsaturates and isO 3899:1988, Rubber - Nitrile latex Determination of residual acrylonitrile content, expands their scope to include other volatile organic components. ii ed without license from IHS Not for Resale
