Thanks thats very usefull.
But...
Maybe I'm blind but I don't see RU or SA.

I suspect they are /country/region/licence/.../ codes.

they are logos for safety testing agencies. The RU is for underwriters laboratory, not sure about the SA

Thanks jrz126.

Safety certificates !

I suspected something like that.

SA is actually CSA and it is Canadian Standard Association (Underwriter's Laboratory's competitor based in Canada)

NOT saftey certificates. Saftey LOGO's If you want to verify certification you have to find out how the device is listed at it's respective agencies. Many cheap chinese nockoff devices will contain these logos which can't be traced back to certification.
