《GB/T 2914-2008塑料 氯乙烯均聚和共聚树脂 挥发物(包括水)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。
本标准于1982年首次发布,1999年第1次修订。本标准规定了两种测定氯乙烯均聚和共聚树脂中挥发物(包括水)的方法。本标准代替GB/T2914―1999《塑料 氯乙烯均聚和共聚树脂 挥发物(包括水)的测定》。本标准与GB/T2914―1999的主要技术差异如下:
―――修改了天平的要求(1999年版3.3,本版3.1.3);
―――修改了加热恒重的要求(1999年版4.3,本版4.1);
―――增加了方法B(本标准3.2,4.2,5.2);
―――增加了“偏差”一章(本标准第6章)。
