Sometimes the code is used to drive product standards in the direction that the CMP wants the standard to go, but the typical future date of 3 years after a code is published is not long enough for a standard to be changed and for products to be designed and listed to the new standard. That future date should be at least 6 years when the new code rule requires a product standard to be revised.I don't know what UL standards are. If you are correct apparently the CMP doesn't know or doesn't care either.
Then there is also the issue of the Standards Technical Panel for GFCIs ignoring data that shows GFCIs can trip below 5 mA where there is high frequency leakage current...such current often exists where power conversion equipment is used to drive motors in the appliance.
I don't see a need for GFCI protection for hard wired equipment expect in some rare cases, like for equipment associated with a pool.
