Copper and copper alloys - Detection of tensile stress - 5 % ammonia test
This standard specifies a medium-duration test using an ammonical atmosphere for the purpose of detecting the
presence of tensile stress, residual or applied, in grades of copper or copper-alloy products that might bring about
failure of a component in service or storage through stress corrosion cracking.
The field of application of this standard is specified in the technical delivery specifications of semi-finished or
finished products in grades of copper and copper alloys, or by prior agreement between purchaser and supplier.
