1 Scope
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:
This standard does not deal with requirements for vibration and noise.
NOTE 1 Compressors for automotive comfort air conditioning systems can be developed according
e.g. SAE J 639.
NOTE 2 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 EN 13445‑8 (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 3 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 intended and under conditions for misuse
which are reasonably foreseeable by the manufacturer (see Clause 4).
This standard specifies safety requirements for the design, construction, manufacture
and testing, documentation and marking of compressors, including integral accessories,
e.g. shut-off valve, if necessary.
The requirements in this standard take account of the intended use, as defined in
3.12 of EN ISO 12100‑ 1:2003.
This standard relates to the compressor itself which is to be incorporated in a refrigerating
system.
This standard is not applicable to compressors as defined in the scope which are manufactured
before the date of publication as EN.
