ISO 3213:2009 聚丙烯管材(PP) 时间和温度对预期强度的影响

标准编号:ISO 3213:2009

中文名称:聚丙烯管材(PP) 时间和温度对预期强度的影响

英文名称:Polypropylene (PP) pipes — Effect of time and temperature on the expected strength

发布日期:2009-09

标准范围

ISO 3213:2009以参考线的形式规定了预期强度的最小值,作为时间和温度的函数,用于计算由以下材料制成的管道:-聚丙烯均聚物(PP-H);-聚丙烯嵌段共聚物(PP-B)(也称为异相共聚物);-聚丙烯无规共聚物(PP-R);-具有改性结晶度(PP-RCT)的聚丙烯无规共聚物(该材料可通过DSC测试或其他适当方法来区分,以指示第二个熔融峰)。

ISO 3213:2009 specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on pipes made of:- polypropylene homopolymer (PP-H);- polypropylene block copolymer (PP-B) (also called heterophasic copolymer);- polypropylene random copolymer (PP-R);- polypropylene random copolymer (this material can be distinguished by DSC testing or another appropriate method to indicate a second melting peak) with a modified crystallinity (PP-RCT).
