本文件规定了以下方法: a） 不间断蠕变试验，持续监测延伸情况； b） 具有周期性伸长率测量的间断蠕变试验； c） 应力断裂试验，通常只测量断裂时间； d） 验证在给定的力下可以超过预定时间的测试，不一定要报告伸长率或伸长率。 注:蠕变试验可以继续进行，直到发生断裂，也可以在断裂前停止。

This document specifies the methods for: a)    uninterrupted creep tests with continuous monitoring of extension; b)    interrupted creep tests with periodic measurement of elongation; c)    stress rupture tests where normally only the time to fracture is measured; d)    a test to verify that a predetermined time can be exceeded under a given force, with the elongation or extension not necessarily being reported. NOTE       A creep test can be continued until fracture has occurred or it can be stopped before fracture.
