1.1 本试验方法适用于测定氯乙烯均聚物和共聚物的残留氯乙烯单体（RVM）含量，其浓度为 ∼ 5微克/千克（ppb）。 1.2 本试验方法适用于任何可溶解在适当溶剂中的聚合物形式，如树脂、化合物、薄膜、瓶壁等。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 第节给出了具体的危险说明 9 和 附注10 . 注1: 本标准等同于ISO 6401。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 含有氯乙烯的聚合物广泛用于包装各种材料，包括食品。 5.2 氯乙烯单体已被证明是人类致癌物。毒性阈值尚未确定。 5.3 塑料制造商、食品包装商、政府机构等。 需要了解含氯乙烯聚合物的残留氯乙烯单体含量。

1.1 This test method is suitable for determining the residual vinyl chloride monomer (RVM) content of homopolymer and copolymers of vinyl chloride down to a concentration of ∼ 5 µg/kg (ppb). 1.2 This test method is applicable to any polymer form, such as resin, compound, film, bottle wall, etc. that can be dissolved in a suitable solvent. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 9 and Note 10 . Note 1: This standard is equivalent to ISO 6401. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Vinyl chloride-containing polymers are widely used to package a variety of materials, including foods. 5.2 Vinyl chloride monomer has been shown to be a human carcinogen. Threshold toxicity value has not been established. 5.3 Plastic manufacturers, food packagers, government agencies, etc. have a need to know the residual vinyl chloride monomer content of vinyl chloride-containing polymers.
