标准摘要
[中文适用范围]： 本文件指定了在高纯水环境中进行金属或合金的单轴恒载应力腐蚀开裂（SCC）试验的方法。该方法特别适用于轻水反应堆（LWRs）的一回水环境模拟。通过该测试方法，可以评估材料在不同环境中的相对抗裂能力以及不同材料在同一环境、试样尺寸和加载条件下的相对抗裂性能。本文件中使用的术语“金属”和“合金”包括焊接金属和焊缝热影响区。 [外文原描述]： The document specifies a method for undertaking uniaxial constant load testing of the susceptibility of a metal, or an alloy, to stress corrosion cracking (SCC) in high-purity water environments at high temperature (above the boiling point of water at normal pressures) and pressure. The test method is particularly applicable to simulated primary water environments of light water reactors (LWRs). The test method enables assessment of the relative resistance to SCC of a material in different environments and the comparative resistance of different materials (using the same environment, specimen dimensions and loading). The terms “metal” and “alloy”, as used in the document, include weld metals and weld heat affected zones.
