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 the execution of its provisions is entrusted toappropriately qualified and experienced people.1 ScopeThis European Standard specifies minimum requirements concerning material, design, construction andworkmanship, procedure and test at manufacture of transportable refillable brazed steel liquefied petroleum gas(LPG) cylinders of water capacity from 0,5 l up to and including 15 l. The limit of 15 l is related to manufacturingprocess available.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.
