Room integrity testing (door fan test)
Door fan testing to verify room leaktightness and predict how long gaseous extinguishing agent stays at design concentration.
Description
Room integrity testing, also called a door fan or blower door test, checks how well a protected room is sealed under the pressure changes of a gas discharge. It predicts how long agents such as Inergen, Novec 1230 or FM-200 will stay at design concentration.
Key points
- Verifies enclosure leaktightness for gaseous systems
- Predicts agent hold time at design concentration
- The page cites AS1851-2005, which requires an enclosure integrity test each year
Applications
Spaces protected by clean agent or inert gas systems.
