《GB/T 12671-2008聚苯乙烯(PS)树脂》由TC15(全国塑料标准化技术委员会)归口,TC15SC1(全国塑料标准化技术委员会石化塑料树脂产品分会)执行,主管部门为中国石油和化学工业联合会。
本标准于1990年首次发布,本次为第一次修订。本标准代替GB 12671-1990《聚苯乙烯(PS)树脂》。本标准规定了聚苯乙烯(PS)树脂的分类命名、要求、试验方法、检验规则、标志、包装、运输和贮存。本标准适用于无定形聚苯乙烯均聚物。本标准与GB 12671-1990相比主要差异如下:
――第2章“规范性引用文件”中,除卫生标准和塑料树脂取样方法标准外均改为注日期的引用文件。
――增加了第3章“分类与命名”。
――增加了第4章“通用要求”。
――在5.1中,删除了原标准中“粒子的尺寸在任意方向上应为(2~5mm)”的要求。
――第5章“要求”中,用“颗粒外观”取代原标准中的“清洁度”,用“简支梁冲击强度”取代原标准中的“悬臂梁冲击强度”。删除了原标准中的“弯曲模量”,增加了“拉伸断裂应力”、“负荷变形温度”等项目。
――第9章中增加了聚苯乙烯树脂贮存期的规定。
――增加了附录A“聚苯乙烯树脂产品国家标准命名与企业商品名对照表”。


Scope

This standard specifies the classification and naming, requirements, test methods, inspection rules, signs, packaging, transportation and storage of polystyrene (PS) resins. This standard applies to amorphous polystyrene homopolymer. This standard does not apply to expandable polystyrene, styrene copolymers, homopolymers of styrene derivatives and those modified with other polymers, such as elastomers.
