本文件规定了在高温水中（如轻水反应堆的模拟水环境）静载荷条件下测定钢和合金应力腐蚀裂纹（SCC）扩展速率的试验方法。在高压釜试验期间，通过电位降法（PDM）监测试样的裂纹长度。 本试验方法适用于不锈钢、镍基合金、低合金钢、碳钢和其他合金。

This document specifies a test method for determining the stress corrosion crack (SCC) growth rate of steels and alloys under static-load conditions in high-temperature water, such as the simulated water environment of light water reactors. The crack length of the specimen is monitored by a potential drop method (PDM) during the test in an autoclave. The test method is applicable to stainless steels, nickel base alloys, low alloy steels, carbon steels and other alloys.
