《GB/T 4615-2008聚氯乙烯树脂 残留氯乙烯单体含量的测定 气相色谱法》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。
本标准代替GB/T4615―1984《聚氯乙烯树脂中残留氯乙烯单体含量的测定方法》。本标准规定了两种采用顶空气相色谱法测定聚氯乙烯(PVC)中残留氯乙烯单体(RVCM)含量的方法,即方法A(液上顶空气相色谱法)和方法B(固上顶空气相色谱法)。本标准于1984年首次发布。本标准与GB/T4615―1984主要差异如下:
―――修改了标准中英文名称;
―――删除了样品瓶的示意图(1984年版图1);
―――将液上法内容列为方法A,附录A 内容列为方法B;
―――增加了采用标准曲线的注(本版6.1.2 注2,7.1.2 注2);
―――增加了使用已知浓度标准气的注(本版6.1.2 注3,7.1.2 注3);
―――修改了标准样配制中注入标准气的体积(1984年版第9章,本版第6章、第7章);
―――修改了固上法的最低检出量(1984年版附录A 第3段,本版第1章);
―――附录B修改为附录A(1984年版附录B,本版附录A)
1 Scope
This Standard specifies two methods for the determination of residual vinyl chlorine monomer (RVCM) in polyvinyl chlorine (PVC) with gas chromatographic method, i.e. Method A (liquid headspace gas chromatographic method) and Method B (solid headspace gas chromatographic method).
Method A of this Standard is applicable to the determination of residual vinyl chlorine monomer in homopolymer and copolymer resins of vinyl chloride and their products; Method B is applicable to the determination of residual vinyl chlorine monomer in copolymer resins of vinyl chloride.
Method B is the arbitration method for the homopolymer of vinyl chloride.
In this Standard, the minimum detection limit of Method A is 0.5 mg/kg, and the minimum detection limit of Method B is 0.1 mg/kg.
