Room integrity test for fire suppression system

When installing a fixed firefighting gas extinguishing system, under NFPA 2001 and BS EN 15004-1, there is a requirement to complete a Room Integrity/Enclosure Test. This test proves that the space being protected has the required structure and integrity, ensuring that the gas, when released, will be retained and held in the correct density [85%] for [10 minutes], ensuring the fire is cooled/extinguished and not able to reignite.
