Specifies a test, using an ammoniacal atmosphere, for the detection of applied or residual stresses which can cause failure of the material in service or storage through stress corrosion cracking. The severity of the method can be regulated by changing the pH value. In an informative annex, recommendations are given for the choice of pH-values.
Abstract
Overview
ISO 6957:1988 - "Copper alloys - Ammonia test for stress corrosion resistance" specifies a laboratory corrosion test that uses an ammoniacal atmosphere to reveal in copper alloys that can lead to in service or storage. The method is simple, reproducible and its severity is of the test solution. An informative annex provides guidance on selecting pH values for common ambient exposure conditions.
