Scope

This Standard specifies symbols and descriptions, principles, test equipment,
samples, test procedures and test reports for a method that uses an incremental
step loading method to measure hydrogen embrittlement threshold stress and
threshold intensity in steel.
This Standard is applicable to quantitatively assess steel's hydrogen
embrittlement sensitivity, or effect of residual hydrogen in steel and hydrogen
outside the environment on steel performance during smelting, hot processing,
surface treatment, etc.
