ISO 11118:2015 specifies minimum requirements for the material, design, inspections, construction and workmanship, manufacturing processes, and tests at manufacture of non-refillable metallic gas cylinders of welded, brazed, or seamless construction for compressed and liquefied gases including the requirements for their non-refillable sealing devices and their methods of testing.NOTE The specific gases permitted in cylinders constructed to this International Standard can be limited by national or international requirements.This International Standard is applicable to cylinders wherea) the 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 capacity does not exceed 1 000 bar·litres (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).

NOTE The specific gases permitted in cylinders constructed to this International Standard can be limited by national or international requirements.
This International Standard is applicable to cylinders where
a) the 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 capacity does not exceed 1 000 bar·litres (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).
La présente norme spécifie les exigences applicables aux robinets pour bouteilles à gaz destinés à être montés sur des bouteilles non rechargeables, ainsi que la méthode d'essai relative à ces robinets pour l'homologation de prototype. NOTE Les bouteilles à gaz métalliques non rechargeables sont spécifiées dans le prEN 12205:1998 et l'ISO/FDIS 11118:1999. La présente norme ne s'applique pas aux robinets pour appareils respiratoires, extincteurs et matériel cryogénique.
This document specifies requirements for the material, design, inspections, construction and workmanship, manufacturing processes, and tests at manufacture of non-refillable metallic gas cylinders of welded, brazed, or seamless construction. This document also specifies the requirements for the non-refillable sealing devices and their methods of testing. It is applicable to non-refillable metallic gas cylinders for compressed and liquefied gases. NOTE The specific gases permitted in cylinders constructed to this document can be limited by national or international requirements. This document is applicable to cylinders where: a) the test pressure does not exceed 250 bar1) (i.e. ph ≤ 250 bar) for liquefied gases and 450 bar for compressed gases; or b) the product of the test pressure and the water capacity does not exceed 1 000 bar·litres (i.e. ph V ≤ 1 000 bar l); or 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). 1) 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2
