Significance and Use |
3.1 This practice, used in conjunction with an appropriate quantitative spark atomic emission spectrochemical method, is suitable for use in manufacturing control, material or product acceptance, and development and research. |
1. Scope |
1.1 This practice covers the sampling of zinc and zinc alloys to obtain a sample suitable for quantitative spark atomic emission spectrochemical analysis. Included are procedures for obtaining representative samples from molten metal, from fabricated or cast products that can be melted, and from other forms that cannot be melted. 1.2 The values stated in SI units are to be regarded as 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, health, and environmental practices and determine 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. |
