ISO 204:2018 金属材料 单轴向拉伸蠕变试验 试验方法

标准编号:ISO 204:2018

中文名称:金属材料 单轴向拉伸蠕变试验 试验方法

英文名称:Metallic materials — Uniaxial creep testing in tension — Method of test

发布日期:2018-08

标准范围

本文件规定了以下方法:a) 不间断蠕变试验,连续监测延伸,b) 定期测量伸长率的间断蠕变试验,c) 通常只测量断裂时间的应力断裂试验,d) 验证在给定力下可超过预定时间的试验,延伸或延伸不一定报告。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 fora) 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.
