This European Standard specifies the requirements for material, design, manufacturing, testing, safety accessories and documentation for stationary pressure vessels intended for use in refrigerating systems and heat pumps, up to being placed on the market. These systems are referenced in this standard as refrigerating systems as defined in EN 378-1. This European Standard applies to vessels including welded or brazed attachments up to and including the nozzle flanges, screwed, welded or brazed connectors or to the edge to be welded or brazed at the first circum-ferential joint connecting piping or other elements. This European Standard applies to the selection, application and installation of safety accessories intended to protect the pressure vessels during the various phases of the refrigeration cycle. This European Standard applies to pressure vessels with an internal pressure down to - 1 bar, to account for the evacuation of the vessel prior to charging with refrigerant. This European Standard applies to both the mechanical loading conditions and thermal conditions as defined in prEN 13445-3 associated with refrigerating systems. It applies to pressure vessels subject to the maximum al-lowable temperatures for which nominal design stresses for materials are derived using prEN 13445-2 and prEN 13445-3 or as specified in this standard. In addition vessels designed to this standard should have a maxi-mum design temperature not exceeding 200 °C and a maximum design pressure not exceeding 64 bars. Outside of these limits, prEN 13445 shall be used for the design construction and inspection of the vessel. Under these circumstances the unique nature of refrigerating plant, as indicated in the introduction to this standard, shall also be taken into account.
