4.3 and 4.4 of this standard are recommended, and the rest are mandatory. Except for G213-1 Safety Rule 3, the main changes of this standard compared with GB2494-1995 are as follows: - C: B2494-19 is mandatory in its entirety. This standard is mandatory in its clauses; GB2494-2003-F24995 Chapter 3 \ "The maximum working speed of the grinding wheel shall not be less than the provisions of the following table", and the production standard is set as "the maximum working speed of the grinding wheel" in the third table of GB2494-1995 is modified to \ "Heavy-duty grinding wheel\", and the heavy-duty grinding wheel with binder is set as 50mm/~80mIm/%, for brown jade F0 and above, and hardness grade M and above The maximum working speed of the grinding wheel is revised to 3am/s, 40mm/5, 50mm/s, and the shape codes of the upper wheel and slow-feed grinding wheel are added. The internal wear of the speed safety blade grinding wheel and the small grinding wheel is excluded: 4.2 in GB2404-1995 is the speed standard 5.1. This standard is proposed by the China Machinery Industry Federation: This standard is approved by the National Abrasives Standardization Technical Committee (SAC/TC19). This standard is drafted by the Zhengzhou Abrasives Research Institute. The main drafters of this standard are Wen Pingsi Xiuying and Zhang Changwu.
