Foreword
This standard is in accordance with the rules of GB/T 1.1 gives drafted.
Instead of the standard YS/T 73-1994 "by-product of zinc oxide." Compared with YS/T 73-1994, this standard main changes are as follows.
--- Product level from the original ten levels changed to five levels;
--- Increased impurity F, Cl requirements;
--- Standardize the arbitration number of samples.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Shuikoushan Hunan Nonferrous Metals Group Limited.
Participated in the drafting of this standard. Henan Yuguang Gold & Lead Co., Ltd.
The main drafters of this standard. Wang Ping, Zeng Guangming, Li Gui, Li Yufeng, Zhao Bo, Shi Lei, Ren Guojun, Zhao, Kuang Su-Qin, Victor Tan Qian,
Xiabing Wei, Wu Shuangxi.
This standard replaces the standards previously issued as follows.
--- YS/T 73-1994;
--- YB810-1977.
By-product of zinc oxide
1 Scope
This standard specifies a byproduct of zinc oxide requirements, test methods, inspection rules, marking, packaging, transportation, storage, quality certificate.
This standard applies to zinc smelting slag and an alloy of zinc oxide obtained by the comprehensive recovery.
