For equipment connected to more than one a phase supply (with or without neutral) does the Standby Regulation apply?

If the equipment only functions connected to more than one phase supply (with or without neutral) the Standby Regulation does not apply. However, if the equipment can both function on single phase and more than one phase supply then the Standby Regulation applies and the equipment shall comply with the requirements when functioning on a single phase; measurements shall be done with a single phase supply.
