The SA helmets also had some flame retardant standards for the liner materials used.

If you read the test standards, both M and SA require multiple impacts in the same location. As I recall there is some difference in the allowable g-forces, but it did not seem like a big difference when I read through it some time ago.
The main difference seems to be that fire proof materials are required for for SA rating.
Too bad that the whole US industry for auto racing and motorcycles has been "brain washed" (so to speak) into believing that Snell is the only acceptable standard.
