Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 633-2007 "cobalt tetroxide." Compared with this standard YS/T 633-2007, the main changes are as follows.
--- Increasing the product category and grade;
--- Chemical components increased requirements and testing methods and magnetic impurity elements Zn foreign body;
--- Physical properties added to the tap density, specific surface area requirements and testing methods;
--- Remove the chemical composition of the S, C content is limited to its detection method.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) and focal points.
This standard is drafted by. High-tech Co., Ltd. Shenzhen Grammy, Jinchuan Group Co., Ltd., Zhejiang Huayou Cobalt
Industry Co., Ltd., Guangdong Science and Technology Co., Ltd. Bump cycle, when l Material Technology Co., Ltd. Beijing.
