Therefore in thiscontext the Standards listed in the normative references and covering basic requirements of the RID/ADR notaddressed within the present Standard are normative only when the Standards themselves are referred to in the RIDand/or in the technical annexes of the ADR.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries 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.SIST EN 12205:2002
Page 4EN 12205:2001IntroductionThe purpose of this standard is to provide a specification for the design, manufacture, inspection and approval of nonrefillable 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 thecountries of the CEN members.Users of cylinders manufactured to this Standard should ensure that they are aware of all relevant regulationsconserning the gases that may be filled into non-refillable cylinders (for example see common position 19/1999 of theCouncil of the EU which specifies that substances which are harmful to the ozone layer shall not be put on the marketin disposable containers except for essential uses). Where a cylinder is used for a harmful gas care should be taken toensure that it is disposed of in a manner that is in accordance with relevant regulations, is safe and meetsenvironmental requirements.1 ScopeThis 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 orseamless construction used for compressed, liquefied and dissolved gases.This Standard is not applicable to cartridges/aerosol dispensers and spherical containers.NOTEFor cartridges, see EN 4172 Normative referencesThis European Standard incorporates, by dated or undated reference, provisions from other publications.
