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. The main drafters of this standard.
