Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 456-2003 "dry aluminum cell with impermeable material." Compared with this standard YS/T 456-2003, the main changes are as follows. --- Product is not classified; --- "Electrolyte reactive" index was revised to "prevent electrolyte penetration" index; --- Increased "bulk density" metric; --- Chemical composition adds "SiO2" and "loss on ignition" indicator; --- Deleted "refractoriness" indicators; --- By the coefficient of thermal conductivity "≤0.55W/(m · K)" changed to "≤0.45W/(m · K)". This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by. China Zhengzhou Research Institute of Chalco, Jiyuan City Lianyuan Furnace Co., Ltd., Zhengzhou Haoyu charcoal Su Materials Co., Ltd. The main drafters of this standard. Li Bo, Zhao more gold, Zhang North Korea, Qiushi Lin, warehouse Xiang-Hui, Xi Yang Zhao. This standard replaces the standards previously issued as follows. --- YS/T 456-2003.
