GB/T 16273.3--1999
This standard specifies 70 general graphic symbols for welding equipment. These symbols are identical to the relevant symbols in the I507000:1989 New Graphic Special Numbers and List, and are used to indicate the characteristics, operating instructions, functional status, etc. of welding equipment. This standard is one of the series of standards for mushroom-shaped symbols for equipment. The series of standards currently has the following three standards: GB/T16273.1-1996 General symbols for graphic symbols for equipment 5 General symbols for graphic symbols for equipment Machine tools
GB/T 16273.2-1996
9 General symbols for graphic symbols for equipment General symbols for welding equipment GR/T 16273.3-1999
This standard shall be implemented from September 1, 1999. This standard is proposed by the China Institute of Standardization and Information Classification and Coding. This standard is under the jurisdiction of the National Technical Committee for Graphic Symbol Standardization. The drafting units of this standard are: China Institute of Standardization and Information Classification and Coding, Beijing Electric Welding Machine Factory. The main drafters of this standard are: Zhang Liang, Bai Dian-, Chen Yuanqiao, Cui Baokun: 1 Scope
