Functional Safety Solutions for Home Appliances (IEC/UL 60730)

The use of automated electronic control systems is expanding in recent years, and reliability and safety requirements are becoming important factors in system design. Due to the establishment of the IEC 60730 safety standard for household electronic equipment, home appliances also require automated electronic control design to guarantee safe and reliable operation.

Automated electronic control is also extremely important in the design of microcontroller-based control systems. There are three classes of software for automated electronic control.

Class A

Control functions that are not intended to be relied upon for the safety of the equipment

Examples: Room thermostats, humidity controllers, lighting controllers, timers, and switches

Class B

Control functions that are intended to prevent unsafe operation of the controlled equipment

Examples: Thermal cutoff and door locking for laundry machines

Class C

Control functions that are intended to prevent special hazards

Examples: Automatic burner control and thermal cutoff for sealed equipment
