Refrigerating systems and heat pumps - Safety and environmental requirements - Part 2: Design, construction, testing, marking and documentation
This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants.
This Part 2 of this Standard is applicable to the design, construction and installation of refrigerating systems including piping, components and materials and including ancillary equipment directly associated with such systems which are not covered in EN 378-1, EN 378-3 or EN 378-4. It also specifies requirements for testing, commissioning, marking and documentation. Requirements for secondary heat transfer circuits are excluded except for any safety devices associated with the refrigerating system. Ancillary equipment includes, for example, fans, fan motors, electrical motors and transmission assemblies for open compressor systems.
The term "refrigerating system" used in this European Standard includes heat pumps.
The standard applies:
a) to refrigerating systems, stationary or mobile, of all sizes, except to road vehicle air conditioners covered by specific product standards such as ISO/DIS 13043 and SAE J 639.;
b) to secondary cooling or heating systems;
c) to the location of the refrigerating systems; and
d) to parts replaced and components added after adoption of this standard if they are not identical in function and capacity.
Systems using refrigerants other than those listed in Annex E of EN 378-1 are not covered by this standard unless they have been assigned to a safety class according to ISO 817.
This standard does not apply to goods in storage.
This standard is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication.
This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site.
This standard also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of parts 1 to 4 of the standard shall be assessed.
