Bundles of seamless steel gas cylinders 1 Scope This document specifies the types and designations, technical requirements, test methods and acceptance criteria, inspection rules, marking, coating, product certificate and quality certificate of bundles of seamless steel gas cylinders (hereinafter referred to as "cylinder bundles"). This document is applicable to mobile cylinder bundles that can be refilled with compressed gas, high (low) pressure liquefied gas or gas mixtures. The nominal working pressure of cylinder bundles shall not more than 30 MPa, the nominal volume of a single cylinder shall not more than 50 L, and the total volume of cylinder bundles shall not more than 3 000 L. The ambient temperature of cylinder bundles shall be -40°C to 60°C. This document is not applicable to the cylinder bundles filled with highly toxic gases, and to the cylinder bundles fixed to vehicle use. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document.
