Is ST working on household electronics appliances Class C Certification?

[NafiurRahman]

I have came across the Library package X-Cube-ClassB which certifies household electronics appliance Class B. I couldn't find anything for class C. Is ST working on developing a Class C library? If so, Can I get a roadmap? If not, can I get support for class C certification?

Hello,
neither X-CUBE-CLASSB nor even X-CUBE-STL libraries can comply stringent requirements of heavy methods acceptable for software testing at Class C level upon all the mcu modules at application when single channel safety structure build upon standard industrial micro is applied. At this case, the most straightforward and effective is a diverse or homogenous dual channel solution with comparison where Class B self tests are applied at both the channels. It is strongly dependent on application hardware, of course. ST can't offer any Class C certified STL software (to be applied at such a single channel structure).
Best regards,
