【国外标准】 Standard Test Method for Analysis of Zinc-5 % Aluminum-Mischmetal Alloys by Inductively Coupled Plasma Atomic Emission Spectrometry

5.1 This test method for the chemical analysis of metals and alloys is primarily intended to test such materials for compliance with compositional specifications. It is assumed that all those who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.1.1 This test method covers the chemical analysis of zinc alloys having chemical compositions within the following limits: Element Composition Range, %  Aluminum   3.0–8.0  Antimony   0.002 max  Cadmium   0.025 max  Cerium   0.03–0.10  Copper   0.10 max  Iron   0.10 max  Lanthanum   0.03–0.10  Lead   0.026 max  Magnesium   0.05 max  Silicon   0.015 max  Tin   0.002 max  Titanium   0.02 max  Zirconium   0.02 max1.2 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 Included are procedures for elements in the following composition ranges: Element Composition Range, %  Aluminum   3.0–8.0  Cadmium   0.0016–0.025  Cerium   0.005–0.10  Iron   0.0015–0.10  Lanthanum   0.009–0.10  Lead   0.002–0.0261.4 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. Specific safety hazards statements are given in Section 8, 11.2, and 13.1.1.5 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.
