The reference to the standard EN137.2006 "Respiratory protective devices with full facepiece self-contained open-circuit compressed air breathing apparatus - Requirements, testing
And signs "(in English) and NFPA1981.2007" with an open fire and emergency self-contained breathing (SCBA) ".
This standard was proposed by the Ministry of Public Security Fire Department.
This standard by the National Standardization Technical Committee firefighters Fire Protection Equipment Technical Committee (SAC/TC113/SC12) centralized.
This standard was drafted. Shanghai Fire Research Institute of Ministry of Public Security.
The main drafters of this standard. Ling Xinliang, Bi win, Shen Jian Min, Huang Hui, Yang Xiaohua, Douchy, Zhangshou Zheng, Yao Haifeng, LIU Ruimin, Lee New Year.
This standard replaces the standards previously issued as follows.
--- GA 124-1996;
--- GA 124-2004.
