标准摘要
[中文适用范围]： 本文件规定了测定聚烯烃管材抗缓慢裂纹扩展的试验方法，以在外表面带有机加工纵向切口的管材上进行静水压试验时的失效时间来表示。 该试验适用于壁厚大于5mm的管道。 [外文原描述]： This document specifies a test method for determining the resistance to slow crack growth of polyolefin pipes, expressed in terms of time to failure in a hydrostatic pressure test on a pipe with machined longitudinal notches in the outside surface. The test is applicable to pipes of wall thickness greater than 5 mm.
