EN 13152:2001 (E)3ForewordThis European Standard has been prepared by Technical Committee CEN/TC 286 "Liquefied Petroleum GasEquipment and Accessories", the secretariat of which is held by NSAI.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by June 2002, and conflicting national standards shall be withdrawn at the latest byJune 2002.This European Standard has been prepared under a mandate given to CEN by the European Commission and theEuropean Free Trade Association, and supports essential requirements of EU Directive(s).In this standard the annexes A and C are normative and the annex B is informative.The standard has been submitted for reference into the RID and/or in the technical annexes of the ADR. Thereforethe standards listed in the normative references and covering basic requirements of the RID/ADR not addressedwithin the present standard are normative only when the standards themselves are referred to in the RID and/or inthe 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 13152:2002



EN 13152:2001 (E)4IntroductionThis European Standard calls for the use of substances and procedures that can be injurious to health if adequateprecautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligationsrelating to health and safety at any stage.It has been assumed in the drafting of this European Standard that execution of its provisions is entrusted toappropriately qualified and experienced people.SIST EN 13152:2002



EN 13152:2001 (E)51 ScopeThis European Standard specifies the requirements for design, specification and type testing for self-closingcylinder valves specifically for use with LPG. It includes references to associated equipment for vapour or liquidservice.NOTEAnnex B gives recommendations for production testing and inspection.This European Standard applies to self-closing valves fitted to transportable refillable LPG cylinders from 0,5 l up to150 l water capacity intended to convey LPG only.This European Standard does not apply to fixed automotive installations.2 Normative referencesThis European Standard incorporates, by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this Europeanstandard only when incorporated in it by amendment or revision.
