This is the harmonized CSA Group and UL standard for particular requirements for motor-compressors. It is the second edition of CAN/CSA-C22.2 No. 60335-2-34, and the sixth edition of UL 60335-2-34. This edition of CAN/CSA-C22.2 No. 60335-2-34 supersedes the previous edition published on March 22, 2013. This edition of UL 60335-2-34 supersedes the previous edition published on March 22, 2013.
This harmonized standard is based on IEC Publication 60335-2-34: Edition 5.2, Household and Similar Electrical Appliances – Safety – Part 2-34: Particular Requirements for Motor-Compressors, issued November 2016. IEC 60335-2-34 is copyrighted by the IEC.
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of sealed (hermetic and semi-hermetic type) MOTORCOMPRESSORS, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to MOTOR-COMPRESSORS tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase MOTOR-COMPRESSORS and 600 V for other MOTOR-COMPRESSORS.
1DV.1 D2 Modification to replace the second sentence of the second paragraph in Clause 1 with the following:
It applies to motor-compressors tested separately, under the most severe conditions that can be expected to occur in normal use, their rated voltage being not more than 300 V for single-phase motor-compressors and 600 V for other motor-compressors intended for use in accordance with:
1DV.2 D2 Modification by adding the following to Clause 1 of the Part 2: For MOTOR-COMPRESSORS rated greater than 600 V, see the requirements of Annex 101.DVI.
This Standard also covers
NOTE 101 Examples of equipment which contain MOTOR-COMPRESSORS are – refrigerators, food freezers and ice makers (IEC 60335-2-24);
This Standard does not supersede the requirements of standards relevant to the particular appliance in which the MOTOR-COMPRESSORS is used. However, if the MOTOR-COMPRESSORS type used complies with this standard, the tests for the MOTOR-COMPRESSORS specified in the particular appliance standard may not need to be made in the particular appliance or assembly. If the MOTOR-COMPRESSORS CONTROL SYSTEM is associated with the particular appliance control system, additional tests may be necessary on the final appliance.
So far as is practical, this standard deals with the common hazards presented by MOTOR-COMPRESSORS used in appliances which are encountered by all persons in and around the home. However, it does not in general take into account
NOTE 102 Attention is drawn to the fact that
NOTE 103 This Standard does not apply to
NOTE 104 If MOTOR-COMPRESSORS for refrigerant R-744 used in appliances with a TRANSCRITICAL REFRIGERATION SYSTEM are equipped with PRESSURE RELIEF DEVICES, compliance with the requirements for these devices is checked during the tests on the final appliance.
