NOTE 2—If heating is used in either of the previous procedures, the container should be covered with a watch glass to prevent loss of HNO3 and water to the atmosphere. Certification method of Practice E Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Caution should be taken when handling mercury and mercury containing products. 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.
