《GB/T 29874-2013塑料 氯乙烯均聚和共聚树脂 气相色谱法对干粉中残留氯乙烯单体的测定》由TC15(全国塑料标准化技术委员会)归口,TC15SC7(全国塑料标准化技术委员会聚氯乙烯树脂产品分会)执行,主管部门为中国石油和化学工业联合会。
本标准规定了氯乙烯均聚和共聚树脂中残留氯乙烯单体的测定方法。
本方法基于静态顶空气相色谱技术(即分析恒定温度下与固相平衡的气相),适用于各种粉末状氯乙烯均聚和共聚树脂。
复合材料、粒料、挤出物、薄膜中的残留氯乙烯单体使用GB/T4615进行测定。
Scope
This standard specifies the determination method for residual vinyl chloride monomer in vinyl chloride homopolymerization and copolymerization resins. This method is based on the technique of static headspace gas chromatography (i.e., the analysis of the gas phase in equilibrium with the solid phase at a constant temperature), and is applicable to various powdered vinyl chloride homopolymer and copolymer resins. GB/T 4615 is used for the determination of residual vinyl chloride monomer in composite materials, pellets, extrudates, and films.
