The US International keyboard layout indeed conforms to ISO/IEC 9995. 
AFAIK it was preexistent, and was validated for conformance by considering that 
the AltGr and Shift + AltGr shift states contain the secondary group. 
I did not think about it as an _implementation_ of ISO/IEC 9995.

The new German standard keyboard layouts T2 and T3 are ISO/IEC 9995.
Other national keyboard layouts before them are, too.
There is exactly a Group 1 with three levels and a Group 2 with two.
