A Room Integrity Fan Test (door fan test) measures how well a protected enclosure retains a gaseous suppression agent by pressurising the room with a calibrated fan and measuring leakage. In data centers it verifies that a clean-agent or inert-gas space will hold the design concentration for the required hold time, a mandatory commissioning and periodic check under standards such as ISO 14520 and NFPA 2001.
