| 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. |

| 1. 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?UnitsThe 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, health, and environmental practices and determines the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
