ASTM B154-01

Standard Test Method for Mercurous Nitrate Test for Copper and Copper Alloys

SCOPE
1.1 This test method describes the technique for conducting the mercurous nitrate test for residual stresses in wrought copper and cast or wrought copper-based alloy products. This test method is intended to cover the mercurous nitrate test of certain copper-alloy products supplied in accordance with ASTM specifications prepared by Committee B05. This test method is not intended to be used on assembled parts.
Note 1—For any particular copper alloy, reference should be made to the material specification.
1.2  Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determines the applicability of regulatory limitations prior to use. For specific precautionary and hazard statements see Sections 1, 6, and 7. (Warning—Mercury is a definite health hazard in use and disposal.)
