The 2 step testing approach is allowed only if both devices (IT + module) are physically separate and are connected only to be coupled on actual use (like an audio receiver and its power amplifier)
The link between EN 301 489-x and Class B is there already since 2001 or so. And was made in purpose, as one cannot limit a Class A radio use to an industrial environment, as is needed for other Class A product (but for the dreaded IT products of course).

Is that correct? In Europe, there is no absolute 'correct', there is only a plausible explanation in your EMC assessment. I think it is perfectly plausible to say that the presence of a Wi-Fi module cannot change a Class A product to Class B. So do your 2-part testing as you propose, but make sure you explain very clearly what you did **and why** in your EMC assessment. >Where can I find the right interpretation? Probably nowhere yet. The link between EN 301 489-1 (note the correct reference) and Class B can be considered an anomaly, highlighted by the introduction of the new Radio Equipment Directive. There may be many such anomalies, some of which may be corrected, but it will take much time. -- OOO - Own Opinions Only. With best wishes.
