Foreword

This standard zinc aluminum rare earth alloy ingot grade class galvanized identical with ASTMB750-2003 "hot-dip zinc-5% aluminum with cerium Alloy ingot standards "standard, hot-dip galvanized zinc-aluminum alloy ingots class grades modify using ASTMB852-2001" hot-dipped steel sheet Zinc continuous hot-dip galvanizing and zinc alloys Standard Specification "standard. Instead of the standard YS/T 310-1995 "hot-dip zinc alloy ingots." Compared with YS/T 310-1995, the present standards are as follows Variety. --- This standard canceled the original standard zinc-aluminum alloys of lead in the original standard based on the increase class zinc-aluminum alloy, zinc aluminum antimony alloys, Zinc-aluminum-silicon alloys. --- The standard for the chemical composition of hot-dip zinc alloy ingots have been adjusted. --- Added singlet was 380kg ± 50kg, hot-dip zinc alloy ingots 8kg ± 2kg, and other specifications. --- Added predetermined test project. --- On the number of samples have been adjusted. --- Canceled YS/T 310-1995 "hot-dip zinc alloy ingots" A, B, C analysis method specified in Appendix, to press GB/T 12689-2004 "zinc and zinc alloy chemical analysis method" in the regulations. --- Added Chapter 8, "orders (or contract) content." The Standard Appendix A, Annex B is an informative annex. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard by Zhuzhou Smelter Group Co., Ltd. is responsible for drafting. The main drafters of this standard. Tan ceremonial, cheap raw Luo, Cai, Miao Hua Lei, Jian Aimin, Zhang fuchsin. This standard replaces the standards previously issued as follows. --- ZBH62002-1985; --- YS/T 310-1995. Hot-dip zinc alloy ingots
