22、 (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations,
23、governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further mai
24、ntenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

33、construction, and initial inspection and testing of non-refillable metallic gas cylinders and their non-refillable sealing devices of the United Nations Recommendations on the Transport of Dangerous Goods: Model Regulations. The purpose of this International Standard is to provide a specification fo
34、r the design, manufacture, inspection, and testing of non-refillable metallic gas cylinders for worldwide safe use, handling, and transport.The objective is to balance design and economic efficiency against international acceptance and universal utility.This International Standard aims to eliminate
35、the concern about climate, duplicate inspections, and restrictions currently existing because of lack of definitive International Standards. This International Standard does not reflect on the suitability of the practice of any nation or region. ISO 2015 All rights reserved viiBS EN ISO 11118:2015BS

37、le 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 l
38、imited 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 forcompressed gases;b) the product of the test pressure and the water capacity does not exceed 1
39、 000 barlitres (i.e.phV 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).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicatio
