Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 5242-2006 "Carbide products inspection rules and test methods." This standard compared with GB/T 5242-2006, the main changes are as follows. --- Added some normative references; --- Test items were adjusted. Added cobalt magnetic, chemical composition, thermal diffusivity, elastic modulus, fall inspection (or beat test), etc. Test items, delete the cross-sectional tissue test items; --- Removed Chapter 3 "Terms and definitions"; --- Removed 4.1.2 "test classification" and 4.4 "test results to determine" content; --- Removed Chapter 5 "Acceptance" content; --- Increased normative appendix A. This standard is proposed by China Nonferrous Metals Industry Association. This standard by the National Non-ferrous Metal Standardization Technical Committee (SAC/TC243) centralized. This standard is mainly drafted by Zigong Cemented Carbide Co., Ltd., Chongyi Zhangyuan Tungsten Co., Ltd., Shenzhen Note into Technology Co., Ltd., Xiamen Golden Egret Special Alloy Co., Ltd. The main drafters of this standard. Cao Wanli, Luo Xiaojun, Jian Yu Mei, Li Siyuan, Xu Xianping, Zhao Guoming, Zhang Shouquan, Sun Xiaoyu. This standard replaces the standards previously issued as. --- GB/T 5242-1985, GB/T 5242-2006. Carbide products inspection rules and test methods
