The OpenADR Alliance announced that the International Electrotechnical Commission (IEC), the world’s leading International Standards organization for all electrical, electronic and related technologies, has approved the OpenADR 2.0b Profile Specification as a full IEC standard, to be known as IEC 62746-10-1 ED1. 

And, of course, this means that all ISY994 Series are now IEC standard compliant!
