Gas cylinders - Non-refillable metallic gas cylinders - Specification and test methods
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; orb) 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); orc) 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

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
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 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).
Le présent document amende la norme homologuée NF EN ISO 11118, de décembre 2015 qui spécifie les exigences minimales applicables aux matériaux, à la conception, aux contrôles, à la fabrication et à la qualité d'exécution ainsi qu'aux procédés de fabrication et aux essais chez le fabricant de bouteilles à gaz métalliques non rechargeables, soudées, brasées ou sans soudure, utilisées pour les gaz comprimés et liquéfiés, y compris les exigences pour leurs dispositifs d'étanchéité non réutilisables et leur méthode d'essai. Il modifie les Références normatives ; les paragraphes 8.1.1.2.1 ; 8.1.1.2.2.1, 8.1.1.2.2.7 (premier alinéa) ; 9.2.2 ; 9.2.4.1 (deuxième alinéa) ; 9.2.4.5 (a) ; 9.2.4.5 (b) ; l'Article 11 ; les paragraphes 12.2.1 (h) ; 12.2.4 (premier alinéa) ainsi que les Articles A.1 ; A.2.2.2.1 ; A.3.2.1 ; A.3.2.2 et A.3.2.6.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
