With the development of my country's economy, the source of urban gas is increasing, especially the exploitation and introduction of natural gas, and the market for household gas heaters is forming day by day. In order to ensure the quality and safety of gas heaters, this standard is specially compiled. This standard is mainly compiled with reference to JISS2122:1996 "Household Gas Heaters" approved by the Japanese Industrial Standards Research Committee and "Gas Appliance Installation Standards and Implementation Guidelines" formulated by the Japan Gas Appliance Testing Association. Because both countries are located in the eastern part of Asia, the climate conditions and living habits of people in China and Japan are relatively similar. In addition, European and American standards were also referred to during the compilation process.
This standard was proposed by the Standard and Quota Research Institute of the Ministry of Construction. This standard is under the jurisdiction of the China Municipal Engineering North China Design Institute, the technical unit responsible for urban gas standards of the Ministry of Construction.
This standard was drafted by Tongji University, Shanghai Gas Sales Group Co., Ltd., Shanghai Oriental Energy Co., Ltd., Shanghai Beixing Industrial Co., Ltd., and Zhanjiang Zhongxin Electric Co., Ltd.
The main drafters of this standard are: Xu Jihuan, Zhu Xianfen, and Shan Guofu. Engineering Construction Standard Full Text Information System
