Scope

This standard specifies the method for detecting residual stress (including applied stress)
in copper and copper alloy processed materials, by ammonia gas accelerated test. These
stresses can cause damage to materials, through stress corrosion cracking, during use
or storage.
This standard applies to the inspection of the residual stress of brass processed materials.
It also applies to the inspection of assemblies and components (limited size).

Summary	This standard specifies the use of ammonia accelerated residual stress (including the applied stress) of copper and copper alloys in assay methods. This stress can lead to material in use or during storage due to stress corrosion cracking and damage. This standard applies to processing material brass residual stress test, also applies to assembly and parts (limited sizes) test.
