Room Integrity refers to the ability for the gaseous agent released in a room to be retained for an extended period of time.

This is critical to the performance of any total flooding clean agent fire extinguishing system, and is a common requirement for premises such as data centres.

The Room Integrity Test is a way to measure the leakage of an enclosure, and to assure that the protected room will hold the clean agent for the required period of time for maximum fire suppression effectiveness.
