标准摘要
[中文适用范围]： 本国际标准以参考线和表格数据的形式规定了作为时间和温度函数的预期强度的最小值，用于对由以下材料制成的管道进行计算： - 聚丁烯-1均聚物（PB-H）和 - 聚丁烯- 1 无规共聚物（PB-R）。 为了简单起见，全文使用聚丁烯名称和缩写PB。 [外文原描述]： ISO12230:2012 specifies minimum values for the expected strength as a function of time and temperature in the form of reference lines and tabulated data, for use in calculations on pipes made of polybutene-1 homopolymer (PB-H), and polybutene-1 random copolymer (PB-R). For the sake of simplicity the designation polybutene and the abbreviation PB are used throughout.
英文名称Polybutene-1 (PB-1) pipes — Effect of time and temperature on the expected strength
