    1.1This 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 378-1.1.2This European Standard applies to piping including welded or brazed attachments up to and including the 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.1.3This 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.1.4This European Standard applies to the following piping:-heat exchanger consisting of piping for the purpose of cooling or heating air where piping aspects are predominant;-piping incorporated into an assembly (e.g. self contained system, condensing unit);-field erected piping.1.5This European Standard applies to piping with an internal pressure down to - 1 bar, to account for the evacuation of the piping prior to charging with refrigerant.1.6This European Standard applies to both the mechanical loading conditions and thermal conditions as defined 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 or as specified in this European Standard. In addition piping designed to this standard needs to have a maximum design temperature not exceeding 200 °C 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 introdu
