《GB/T 4618.2-2008塑料 环氧树脂氯含量的测定 第2部分:易皂化氯》由TC15(全国塑料标准化技术委员会)归口,TC15SC11(全国塑料标准化技术委员会热固性塑料分会)执行,主管部门为中国石油和化学工业联合会。
GB/T 4618《塑料 环氧树脂氯含量的测定》共分为三个部分,本部分为GB/T 4618的第2部分,等同采用ISO 21627-2:2002《塑料――环氧树脂――氯含量的测定――第2部分:易皂化氯》(英文版)。
本部分代替GB/T 4618-1984《环氧树脂和有关材料易皂化氯的测定》。
GB/T 4618的本部分规定了环氧树脂中易皂化氯的测定方法。
本部分与GB/T 4618-1984相比主要变化如下:
―――更改了标准名称、增加了前言;
―――增加了规范性引用文件;
―――增加了术语和定义;
―――氢氧化钠分为用于环氧树脂测试的2-丁氧基乙醇溶液和用于缩水甘油酯测试的甲醇溶液;
―――溶液浓度单位由N改成mol/L;
―――基准试剂氯化钠干燥温度由120℃改成500℃~600℃。
Scope
Warning: Personnel using this part of GB/T 4618 should be familiar with general laboratory rules. This section does not address any security issues associated with use. It is the user's responsibility to establish appropriate safety and health practices and comply with relevant regulations. This part of GB/T 4618 specifies the method for the determination of saponifiable chlorine in epoxy resin. The saponifiable chlorine content is the amount of readily saponifiable chlorine in a given amount of epoxy resin. The obtained value represents the readily saponifiable chlorine concentration of the chlorohydrin group in the compound.
