适用范围：1.1 This European Standard specifies the requirements for material, design, manufacturing, testing and documentation for stationary piping intended for use in refrigerating systems, heat pumps and secondary cooling and heating systems. these refrigerating systems and heat pump systems are referenced in this standard as refrigerating systems as defined in EN 378-1.1.2 This European Standard applies to piping including welded or brazed attachments up to and includingthe flanges, screwed, welded or brazed connectors or to the edge to be welded or brazed at the first circumferential joint connecting piping or other elements.1.3 This European Standard applies to the selection, application and installation of safety accessories intended to protect the piping during the various phases of the refrigeration cycle.1.4 This European Standard applies to the following piping:-heat exchanger consisting of piping for the purpose of cooling or heating air where piping aspects arepredominant;-piping incorporated into an assembly (e.g. self contained system, condensing unit);-field erected piping.1.5 This European Standard applies to piping with an internal pressure down to-1 bar, to account for theevacuation of the piping prior to charging with refrigerant.1.6 This European Standard applies to both the mechanical loading conditions and thermal conditions asdefined in EN 13480-3 associated with refrigerating systems. It applies to piping subject to the maximum allowable temperatures for which nominal design stresses for materials are derived using EN 14276-1-2006+A1 or as specified in this european standard. In addition piping designed to this standard needs to have a maximum design temperature not exceeding 200℃ and a maximum design pressure not exceeding 64 bar. Outside of these limits, EN 13480 should be used for the design construction and inspection of the piping. under these circumstances the unique nature of a refrigerating plant, as indicated in the introduction of EN 14276-1-2006+A1, needs also to be taken into account.1.7 This European Standard applies to piping where the main pressure bearing parts are manufactured from metallic ductile materials as defined in Clause 4 and in EN 14276-1-2006+A1.
