Rules for the Filling of Liquefied Gas Cylinders-Part 1: Industrial Gas Cylinders
1 Scope
This document specifies the basic requirements, filling process control, filling coefficient and filling quantity, filling records, and filling quality and safety traceability information system for industrial gas cylinders (hereinafter referred to as "gas cylinders") for filling with liquefied gases.
This document applies to the filling of high-pressure liquefied gas cylinders and low-pressure liquefied gas cylinders (where the saturated vapor pressure at the maximum operating temperature is not less than 0.1 MPa (gage pressure)) for industrial gas cylinders.
This document does not apply to the filling of motor vehicle gas cylinders, fuel gas cylinders, and fire-fighting gas cylinders.
