EN 378-2:2008

This European Standard is applicable to the design, construction and installing of refrigerating systemsincluding piping, components and materials and including ancillary equipment directly associated with suchsystems. It also specifies requirements for testing, commissioning, marking and documentation. In case theheat transfer fluid is not gaseous at atmospheric pressure, the requirements for circuits for heat transfer fluidsare excluded except for any safety devices associated with the refrigerating system. It is not applicable torefrigerating systems with air or water as refrigerant and does not cover the requirements for equipment to beused in a potentially explosive atmosphere.The following ancillary equipment includes:- fan and fan motor;- electrical motor and transmission for open compressor systems.This European Standard specifies the requirements relating to stationary and mobile refrigerating systems ofall sizes, including heat pumps.Systems using refrigerants other than those listed in Annex E of EN 378-1:2008 are not covered by thisstandard as long as a safety class is not assigned.Basic safety requirements for refrigerating systems as defined in EN 378-1 are applicable for this standard.Basic requirements for the installation site as defined in EN 378-3 apply.This European Standard is not applicable to refrigeration systems and heat pumps which are manufacturedbefore the date of its publication as EN.
