This document specifies the types and models, technical requirements, test methods, and qualification standards of steel seamless gas cylinder cluster devices (hereinafter referred to as cluster devices). It also covers inspection rules, marking, coating, product quality certificates, and product quality proofs. This document applies to mobile cluster devices that can be refilled with compressed gases, high-pressure (low-pressure) liquefied gases, or mixed gases. The nominal working pressure of the cluster devices shall not exceed 30 MPa, the nominal volume of a single gas cylinder shall not exceed 450 L, and the total volume of the gas cylinders in the cluster device shall not exceed 3,000 L. The operating temperature of the cluster device shall be between -40℃ and 60℃. This document does not apply to cluster devices filled with gases classified as highly toxic, nor to cluster devices fixed on vehicles for use.
