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?

  1. Expandable door panels
  2. Configuration of the range and calibrated fan(s)
  3. Laptop computer,
  4. Calibrated gauges,
  5. 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.
