IEC 60730 Safety Standard for Household Appliances

Last Updated:

The International Electro-technical Commission (IEC) has developed safety standard IEC 60730 that discusses mechanical, electrical, electronic, environmental endurance, EMC, and abnormal operation for home appliances.

The IEC 60730 standard classifies appliance software into three categories:

  • Class A - Control functions that are not intended to be relied upon for the equipment's safety such as humidity controls, lighting controls, timers, and switches.
  • Class B - Control functions that are intended to prevent unsafe operation of the controlled equipment such as thermal cut-offs and door locks for laundry machines.
  • Class C - Control functions that are intended to prevent special hazards. Examples are automatic burner controls and thermal cut-outs for closed, unvented water heater systems.

Major home appliance products, such as washing machines, dishwashers, dryers, refrigerators, freezers, and cookers/stoves, tend to fall under the Class B classification. An exception is an appliance that might cause an explosion, such as a gas-fired controlled dryer that falls under Class C.

Cypress has developed safety features, including IEC 60730 Safety Library along with application notes to help manufactures meet the regulation with PSoC devices.
