GB 17265-1998 Safety technical requirements for liquefied gas cylinder filling stations
Some standard content:
GB 17265—1998
This standard is specially formulated to ensure the filling safety of liquefied gas cylinders and to regulate the safety and technical conditions of liquefied gas cylinder filling stations in various industries.
This standard is closely related to GB14193-93 "Regulations on Filling Liquefied Gas Cylinders". The former makes specific provisions on the construction requirements, personnel conditions, plant equipment, safety facilities, management system and other aspects of liquefied gas cylinder filling stations; the latter, on the basis of the former, makes more detailed requirements on the safety and technical protection of liquefied gas cylinder filling stations. The formulation of this standard is mainly guided by the "Regulations on Safety Supervision of Gas Cylinders" promulgated by the Ministry of Labor in December 1989, and quotes some national standards and industry standards that have been promulgated and implemented in my country. It is hoped that relevant personnel will implement the cited standards while implementing this standard. This standard is formulated for the first time in China. Since no relevant international and foreign standards have been found, it is only written based on the current national conditions. Considering the introduction of advanced technology, the development of the gas cylinder filling industry and the requirements of aligning with international standards, it is hoped that relevant personnel will pay attention to collecting relevant information for the purpose of revising and republishing this standard.
This standard is proposed by the Ministry of Labor of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee for Standardization of Gas Cylinders and is responsible for its interpretation. The drafting units of this standard are: Calcium Carbide Plant of Jilin Chemical Industry Co., Ltd., Fertilizer Plant of Jilin Chemical Industry Co., Ltd., and Beijing Chemical Experimental Plant.
The main drafters of this standard are: Wang Zhongyuan, Zhu Bing, and Hu Jincheng. This standard is published for the first time.
