BS ISO 16540:2015提供了使用四点弯曲试验来评估 碳钢、低合金钢和耐腐蚀合金（CRA）等金属的耐腐蚀性 应力腐蚀开裂。该方法为母板和焊缝的测试提供了指导，以及 包括在应力应变行为中没有明显屈服点的金属的程序 以及具有明显屈服点的金属。本国际标准的重点是通用标准 四点弯曲试验的方法。服务申请将有所不同，相关行业也会有所不同 在适当的情况下，应参考标准。交叉引用:ISO 8407ISO 6892-1ISO 6892-2ISO 7539-1ISO 7539-2ISO 7539-8ISO 8044ISO 11463ASTM A380-99（2005）ASTM F21 65（2007）购买本文件时，所有当前可用的修订都包括在购买本文件中。

BS 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.Cross References:ISO 8407ISO 6892-1ISO 6892-2ISO 7539-1ISO 7539-2ISO 7539-8ISO 8044ISO 11463ASTM A380-99 (2005)ASTM F21 65 (2007)All current amendments available at time of purchase are included with the purchase of this document.
