Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 71-2004 "crude lead." Compared with YS/T 71-2004 "crude lead", the main changes are as follows.
--- Remove the chemical composition of crude lead content requirements of impurity Cu;
--- Large crude lead ingot rings made of tare requirements;
--- Large drill crude lead ingots arbitration law the number of samples has been modified;
--- Added small crude lead ingot, crude lead ingot melting process large arbitration sampling methods;
--- Added after melting of crude lead slag samples sampling methods;
--- Crude lead transport, storage has been modified.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Henan Yuguang Gold & Lead Co., Ltd., Hunan Shuikoushan Nonferrous Metals Group Co., Ltd. Zhuzhou Smelter
Group Co., Ltd.
The main drafters of this standard. Gui, Wang Ping, Tan Yi-Wen, often national war, Jiang Dongsheng, Hu, Zhou Wenying, Tangru Fu, Peng Hailiang, Gou Tao.
This standard replaces the standards previously issued as follows.
--- YS/T 71-1993, YS/T 71-2004;
--- YB38-1982.
