ISO 11118 pdf download.Gas cylinders — Non-refillable metallic gas cylinders — Specification and test methods 1 Scope This International Standard specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes and tests at manufacture of non-refillable metallic gas cylinders of welded, brazed or seamless construction for compressed, liquefied and dissolved gases exposed to extreme worldwide ambient temperatures. NOTE The specific gases permitted in cylinders constructed to this International Standard may be limited by ISO, national requirements or international requirements. This International Standard is applicable to cylinders where: a) the maximum permissible operating pressure does not exceed 250 bar (i.e. p ms < 250 bar); b) the product of the maximum permissible operating pressure and the water capacity does not exceed 1 000 bar.litres (i.e. p ms . V < 1 000 bar.l); c) where the maximum permissible operating pressure exceeds 35 bar, the water capacity does not exceed 5 l (i.e. for p ms . 35 bar, then V < 5 l). This International Standard is not applicable to cylinders exceeding these pressure and volume limits, for which reference may be made to refillable cylinder standards. This International Standard is also not applicable to cartridges/aerosol dispensers 1 ) and spherical containers. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
