NF EN ISO 11118, E29-695 (01/2025)

ISO 11118:2015 specifies the minimum requirements for materials, design, controls, manufacturing and workmanship as well as manufacturing processes and testing by the manufacturer of non-refillable metal gas cylinders, welded, brazed or seamless, used for compressed and liquefied gases, including requirements for their non-reusable sealing devices and their test method. NOTE The specific gases permitted for non-refillable cylinders constructed in accordance with this International Standard may be limited by national or international requirements. This International Standard is applicable to non-refillable cylinders whose: a) test pressure does not exceed 250 bar (i.e. ph = 250 bar) for liquefied gases and 450 bar for compressed gases; (b) the product of the test pressure and the water content does not exceed 1,000 bar·liters (i.e. ph V = 1,000 bar l); c) the test pressure exceeds 45 bar and the water capacity does not exceed 5 l (i.e. for ph > 45 bar, then V = 5 l).
