标准范围

ISO 13479:2009规定了一种测定聚烯烃管道抗慢速裂纹扩展能力的试验方法，用外表面带有机加工纵向缺口的管道的静水压试验中的失效时间表示。本试验适用于壁厚大于5mm的管道。

ISO 13479:2009 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.
