Welded insulated cylinders 1 Scope This document specifies symbols, designation, basic parameters, materials, design, manufacturing, test methods, inspection rules, type tests, marking, packaging, transportation, end-of-manufacturing documents and data retention, among others, for welded insulated cylinders (hereinafter referred to as “cylinders”). This document is applicable to refillable cylinders intended for use at normal ambient temperature (-40 °C to 60 °C), with nominal capacity of 10 L to 1000 L for storing liquid oxygen, liquid nitrogen and liquid argon, nominal capacity of 150 L to 1000 L for liquefied natural gas, design temperature up to -196 °C and nominal working pressure of 0.2 MPa to 3.5 MPa. For cylinders storing liquid carbon dioxide and liquid nitrous oxide, this standard may apply in terms of manufacture and inspection. Note: Any pressure not specified in this standard refers to the gauge pressure. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document.
