标准摘要
[中文适用范围]： 本国际标准提供了使用四点弯曲测试来评估金属（包括碳钢、低合金钢和耐腐蚀合金（CRA））对应力腐蚀开裂的抵抗力的指南。 该方法为母板和焊缝的测试提供了指导，并包括应力应变行为没有明显屈服点的金属以及具有明显屈服点的金属的程序。 本国际标准的重点是四点弯曲测试的通用方法。 服务应用会有所不同，并酌情查阅相关行业标准。 [外文原描述]： ISO 16540:2015 provides guidelines for the use of four-point bend testing to evaluate the resistance of metals including carbon steel, low alloy steels, and corrosion resistant alloys (CRAs) to stress corrosion cracking. The method gives guidance on testing of both parent plate and welds and includes procedures for metals that have no distinct yield point in their stress-strain behaviour as well as metals with a distinct yield point. The emphasis in this International Standard is on the generic methodology of the four-point bend test. Service application will be varied and the relevant industry standard is to be consulted where appropriate.
