This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2001, and conflicting national standards shall be withdrawn at the latest by November 2001. This European Standard has been prepared under a mandate given to CEN by the European Commission and the Free Trade Association, and supports the objectives of the Framework Directives on Transport of Dangerous Goods. This standard has been submitted for reference into the RID and/or the technical annexes of the ADR. Therefore, in this context, the standards listed in the normative references and covering basic requirements of the RID/ADR not addressed within the present standard are normative only when the standards themselves are referred to in the RID and/or in the technical annexes of the ADR. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction The purpose of this standard is to provide a specification for the design, manufacture, inspection and approval of non-refillable metallic gas cylinders. The specifications given are based on knowledge of, and experience with, materials, design requirements, manufacturing processes and control during manufacture of cylinders in common use in the countries of the CEN members. Users of cylinders manufactured to this standard should ensure that they are aware of all relevant regulations concerning the gases that may be filled into non-refillable cylinders (for example see common position 19/1999 of the Council of the EU which specifies that substances which are harmful to the ozone layer shall not be put on the market in disposable containers except for essential uses). Where a cylinder is used for a harmful gas, care should be taken to ensure that it is disposed of in a manner that is in accordance with relevant regulations, is safe and meets environmental requirements. 1 Scope This European 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 used for compressed, liquefied and dissolved gases. This standard is not applicable to cartridges/aerosol dispensers and spherical containers. NOTEFor cartridges, see EN 417 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 287-1, Approval testing of welders Fusion welding Part 1: Steels.
