scope:

The document specifies the methodology 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 methodology 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 to 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.
