1   Scope This British Standard sets out a controlled method to determine specific fan power (SFP) of fan coil units (FCU) as a function of the volume flow rate of air. This British Standard covers ducted, non-ducted and cassette FCUs that can be standing on the floor, hung on the wall, or fitted into the ceiling or floor, with the inlet and outlet air sections located either on the front, back, bottom or top of the unit. This British Standard also defines FCU configuration for test purposes.
