Articles 6 and 8 of this standard are mandatory clauses, and the rest are inductive clauses. LY/11512-2003 standard was implemented, and replaced 11512:934 ordinary cattle (original B8931981.Y/T1601992 refined H fetal (A type.33/153-15 and /-commercial items) standard revision. According to the points of the essential health type, combined with the cattle production situation in four months, the above two standards were merged into one standard to measure the entry and exit of the two health cattle. The six standards were revised in the following aspects, and relevant terms and definitions were added:
for the essential health type Chopsticks are classified according to different shapes! The size range and technical indicators are revised: the standard is issued by the National Bureau of Transportation. This standard is issued by the China Technical Committee for Standardization of Materials Science and Technology. This standard is undertaken by the Heilongjiang Provincial Foreign Industry Research Institute. The drafting units of the wood standard are Erbin Forestry Machinery Equipment Processing Factory, Dingzhijiang Qing'an State-owned Forest Farm Management Team, Shenzhen Wood Factory, and the North Forestry Pipe Factory. The main drafters of the wood standard are: Li Miankao, Hua Xiaoqin, Man Xiaoling, Zhao Chuan, This standard is promoted by the China National Standardization Development Committee.
