Actually, what I found initially was not the full standard. It seems that 62040-3 mentions that to be compliant with 62040-3, you also need to be compliant to 62040-1 and 62040-2.
62040-1 is the UPS safety requirements and 62040-2 is the EMC compatibility.
So it is probably a bit more involved than just saying VFD YY 333 and being done with it.
