I didn't mean a formal standard - I checked the definitions and what I'm referring as is that US generally prefers central or "packaged" systems (single big unit in the utility room, air is piped from there into the living space through various ducts) where as Europe prefers "split" systems where you have units in each room with refrigerant pipes going back to the outdoor unit.

Most of the US uses split units for central air (split meaning the condenser and evaporator are in separate units). What you’re calling a “split” is more precisely called a “ductless (mini-)split” as even an evaporator in the mechanical room and linesets carrying refrigerant to an outdoor condenser is still a (conventional) split setup.
