Room Integrity test
A room integrity test examines the room’s construction, air leakage rate, and, most significantly, its capacity to contain fire-fighting gases. Without releasing the extinguishing gas itself, room integrity testing may forecast the retention time and leakiness of a room. The air tightness and amount of air leakage in a room are determined by room integrity tests based on the pressure differential that occurs during testing.
What equipment is involved in Room Integrity Test?
- Expandable door panels
- Configuration of the range and calibrated fan(s)
- Laptop computer,
- Calibrated gauges,
- Enclosure integrity software
Room Integrity Test Procedures
- All AHUs and ACs in the test room will be turned off.
- The test’s direction will be decided by the tester.
- “Door Fan Test Panels / Plastic Sheet” will be used to seal the door of the room undergoing testing.
- Seal tapes will be used to close any little holes that may exist.
- The Blower Fan for the Room Integrity Test will be mounted on the Panel.
- The power wire and all capillary tubes are attached.
- With the help of the Controller, the Fan is turned ON.
- All design information is input in the room integrity software that is installed on the computer before turning on the fan.
- The pressure in the room has been increased to the test pressure recommended by the software.
- The data for the flow rates and pressure are recorded.
- In a similar manner, the room is depressurized and observations of the pressure and flow rate are collected.
- The Room Integrity software is updated with the reported readings.
- The software will display the room’s anticipated leakage area and retention duration.
- The room passes the test if the retention time is greater than 10 minutes (NFPA 2001:2012 Clause 5.6).
The good news is AITO has capable technician that can possess the required abilities and information.
