Actually I believe it was if it was exempt from compliance issues because of ISM under 15.103 (mistakenly referred to as 15.123. From there it went to the issue of it being a piece of test equipment that met the exemption, etc etc etc. The Class A or B came about after that discussion. But you are correct, either Class A or Class B must meet the associated technical standards.

The original post was not class A vs. Class B, but whether any FCC requirement applied. I can't see how they could not be required to qualify to class A.
