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.#,,#
