This document specifies the basic methods and technical requirements for the regular inspection and evaluation of pressurized gas cylinders used for fire extinguishing. This document applies to rechargeable steel seamless gas cylinders used for fire extinguishing, with a nominal working pressure not exceeding 30 MPa and a nominal volume of 3 L to 150 L, which are used to contain compressed gases, high-pressure liquefied gases, or mixed gases. This document applies to rechargeable steel welded gas cylinders used for fire extinguishing, with a nominal working pressure not exceeding 10 MPa and a nominal volume of 4 L to 1,000 L, which are used to contain liquids with a standard boiling point below or equal to 60 °C, low-pressure liquefied gases, or mixed gases. This document does not apply to gas cylinders used for fire extinguishing that only withstand instantaneous pressure during fire extinguishing, as well as gas cylinders used for fire extinguishers.
