CAN/CSA-E335-2-34-94

1. Scope This clause of Part 1 is replaced by the following: Replacement: 1.1 This standard applies to sealed (hermetic and semi-hermetic type) motor-compressors intended for use in air-conditioning and refrigerating equipment for household and similar uses which conform with the standards applicable to such equipment. It also applies to motor-compressors for use in factory-built assemblies for transferring heat in applications for refrigerating, air-conditioning or heating purposes or a combination of such purposes. Attention is drawn to the fact that this standard does not take into consideration the special conditions of use which may occur when the appliance incorporating a motor-compressor is operating in locations where special conditions, such as explosive atmosphere, prevail. 1.2 These requirements apply to sealed motor-compressors tested separately, under the most severe conditions which, within reasonable limits, could occur in normal use. They do not supersede the requirements of existing standards relevant to the kind of application such as IEC Publication 335-2-24, Part 2: Particular Requirements for Refrigerators and Food Freezers, or IEc Publication 378: Safety Requirements for the Electrical Equipment of Room Air-conditioners, but if the compressor type used complies with these particular requirements, the tests for motor-compressors specified in the standard referred to, may not need to be made in the appliance or assembly.
