IEC 60335-2-34:2012 PDF Download

The safety criteria for motor-compressors used in household appliances and related electrical appliances are the topic of the standard IEC 60335-2-34:2012. The hermetic and semi-hermetic varieties of sealed motor-compressors, as well as their control and protection mechanisms, are covered by the standard. It applies to motor compressors used in machinery that complies with the appropriate standards for home appliances and similar items.

Separate motor-compressors are put through the harshest tests possible as part of the standard operating procedure. It covers other motor-compressors with a rated voltage of up to 480 V as well as single-phase motor-compressors with a voltage range of up to 250 V. Refrigerators, air conditioners, dehumidifiers, electric heat pumps, commercial dispensing appliances, vending machines, and factory-built assemblies for heat transfer are a few examples of equipment that may feature motor-compressors.

Even though this standard does not supersede the criteria of certain appliance standards, it might not be necessary to carry out some tests if the motor-compressor being used conforms to IEC 60335-2-34. However, extra testing on the finished appliance might be necessary if the motor-compressor control system is linked with the appliance control system.

It is crucial to remember that IEC 60335-1:2010, which outlines general safety criteria for home appliances and other comparable electrical devices, should be read in combination with this standard.
