Functional Safety Solutions for Home Appliances Class C

The IEC 60730 standard applies to automatic electronic controls for household appliances and appliances for similar purposes. IEC 60730 Appendix H defines the design, test and diagnostic methods for electronic safety control requirements in detail, including Class C software requirements for protection against special hazards, such as for cooking stoves.

Renesas Electronics offers sample programs and application notes for the self-test program for the microcontrollers and obtained certification for the IEC 60730 Class C standard from the certification bodies VDE, UL and TÜV Rheinland.
