Can I apply IPC-610 class 3 workmanship standards to an assembly made with a IPC-600 class 2 PCB?

I have asked that same question to a co-chair of the J-STD-001 committee who in turn checked with personnel at IPC. The answer I received is that yes you can apply the Class 3 assembly requirements using a class 2 PWB but the resultant assembly will be no greater than Class 2. If the customer requires Class 3 hardware then you must start with a Class 3 PWB. I hope that helps.
