|ICS Code (Copper and copper alloys):||77.120.30|
This method describes the technique for conducting the mercurous nitrate test of commercial wrought copper and east or wrought copper-base alloy products. This is an accelerated test for the purpose of detecting in copper or copper•base alloy products the presence of residual (internal) stresses that might bring about failure of the material in service or storage through stress-corrosion cracking. This method is intended to cover the mercurous nitrate test of certain copperalloy products supplied in accordance with ASTM specifications prepared by Committee B-5. If it is used for testing assemblies and fabricated parts, failure shall not be ca use for rejection of the original mill product.
NOTE 2-For any particular copper alloy, reference should be made to the material specification.
NOTE 3- The values stated in U.S. customary units are to be regarded as the standard.
