(Test Method)Standard Test Method for Mercurous Nitrate Test for Copper Alloys
Standard Test Method for Mercurous Nitrate Test for Copper Alloys
SIGNIFICANCE AND USE
5.1 This test method is an accelerated test for detecting the presence of residual (internal) stresses that might result in failure of individual parts in storage or in service due to stress corrosion cracking.
5.2 This test method is not intended for use on assemblies or parts under applied stress. If used for that purpose, the results shall be for information only and not a cause for rejection of the assembly, its component parts, or the original mill product.
SCOPE
1.1 This test method describes the technique for conducting the mercurous nitrate test for residual stresses in wrought copper alloy mill products.
Note 1: For any particular copper alloy, reference should be made to the material specification.
Note 2: Test Method B858 may be considered as a possible alternative test method which does not involve the use of mercury.
Note 3: This test method is considered historically reliable for determining the potential state of residual stress in copper alloys, but not promoted for use due to the hazards relating to mercury use and environmentally appropriate disposal.
1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law.)
