Gas filling group standard

Excuse me, are you asking the question "Who formulated the group standard for gas filling"? Group standards for fuel filling are mainly formulated by relevant industry associations or organizations, which regulate the operation process and requirements of gas filling.

For example, the group standard "Specification for Filling Bottled Liquefied Petroleum Gas" issued by Foshan Gas Industry Association stipulates terms and definitions, measurement requirements, measurement instruments and communication equipment requirements, filling operation requirements and inspection rules.
