This International Standard specifies a test, using an ammoniacal atmosphere, for the detection of applied or residual stresses in copper alloy products which can cause failure of the material in service or storage through stress corrosion cracking. The method can also be used for testing assemblies and partial assemblies (of limited size). This method is relatively simple to carry out and its severity can be regulated by changing the pH value of the solution producing the ammoniacal atmosphere. The appropriate pH-value for the test shall be specified in the product specification or agreed upon with respect to the alloy and its application. In annex A, recommendations are given for the choice of pH-values to be used for some frequently occuring applications.
