What is a Room Integrity Test?
An Integrity test predicts how long fire suppressant agents take to descend to a given level in the room without having to release the agent itself.
The Integrity test is carried out using:
Modular adjustable panels for the door frame which adjusts to fit a wide variety of door sizes.
calibrated Fan and range configuration
Enclosure Integrity Software
The system is setup in an available doorway. The protected area is then pressurised and the fan flow readings are taken, then to check those measurements the room is depressurised to take measurements to compare. The predicted retention time is calculated from the leakage characteristics and the enclosure and extinguishing system data.
A retention time of 10 minutes is the normal minimum period clean agent suppressant agents. Ten minutes is long enough for most deep-seated fires to be cooled so that re-ignition is unlikely. Gaseous fire suppression systems should provide adequate time for the fire emergency services to attend and in most cases prevent the fire taking hold.
When do I need an Integrity Test?
When you have a gaseous suppression system installed, your protected area will need testing to ensure that the suppressant is maintained within the area and will work in case of fire. It is a requirement of most insurance policies and South African SANS standards that your suppression system is tested annually.
An Integrity re-test is also required if any modifications are made to the area.
Moving a partition, fitting a new door, installing new cables or pipes or in any way modifying the structural perimeter of an enclosure will almost certainly affect gaseous fire suppression retention.
Any changes to the room (no matter how small or inconsequential they may seem) will require a retest carried out.
