Harmonized under:
  • Directive 2006/42/EC of the European Parliament and of the Council of 17 May 2006 on machinery, and amending Directive 95/16/EC (recast

Harmonized standards:


This standard applies to positive displacement refrigerant compressors for stationary and mobile refrigerating systems and heat pumps defined in 3.1, hereafter called compressors.
It applies for compressors used in commercial and industrial appliances and with electrical energy supply including integral motors, up to 1 000 VAC and 1 500 VDC.
It applies to open drive, semi hermetic and hermetic motor compressors, which contain a positive compression function
This standard is not applicable to:
- compressors used in household appliance for which EN 60335-2-34 applies;
- compressors using water or air as refrigerant.
This standard does not deal with requirements for vibration and noise.
NOTE – Noise emission depends on the complete installation of the built-in compressors and the corresponding operating conditions.
For semi-hermetic and open drive compressors which include moving parts and for which the external envelope is primarily designed for mechanical loads, thermal loads (to limit the possible deformation due to temperature), stiffness of the structure (external mechanical loads and weight of the equipment), taking into account established safe industrial practice, it is considered that pressure is not a significant design factor.
Attached parts covering other functions e.g. oil separators, oil coolers, suction accumulators shall comply to EN 14276-1 or EN 13445-6 (cast iron) or prEN 13445-8:2003 (aluminium) or showing compliance to the relevant European requirements. This applies also to shells for hermetic compressors either welded or with any kind of permanent joint.
Requirements for compressors used in explosive atmospheres are not covered by this standard.
NOTE – For further guidance see EN 13463-1.
This standard deals with all significant hazards, hazardous situations and events relevant to compressors, when they are used as indented and under conditions for misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
