This European Standard specifies the requirements for material, design, manufacturing, testing, safety accessories and documentation for stationary piping intended for use in refrigerating systems, heat pumps and secondary cooling and heating systems, up to being placed on the market. These refrigerating systems and heat pump systems are referenced in this standard as refrigerating systems as defined in EN 378-1. This 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. 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. This European standard applies to the following pipings: - heat exchanger consisting of piping for the purpose of cooling or heating air - piping incorporated inside self-contained systems - field erected piping. This 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. This European Standard applies to both the mechanical loading conditions and thermal conditions as defined in EN 13480-3:2002 associated with refrigerating systems. It applies to pipings subject to the maximum allowable temperatures for which nominal design stresses for materials are derived using prEN 14276-1:2002 or as specified in this standard. In addition pipings designed to this standard shall have a maximum design temperature not exceeding 200 °C and a maximum design pressure not exceeding 64 bars. Outside of these limits, EN 13480 shall be used for the design construction and inspection of the piping. Under these circumstances the unique nature of refrigerating plant, as indicated in the introduction of prEN 14276-1:2002, shall also be taken into account. This European standard applies to pipings where the main pressure bearing parts are manufactured from metallic ductile materials as defined in clause 4 of this standard and in prEN 14276-1:2002.
