About the Room Integrity Test
The Room Integrity Test is a fundamental technical requirement for spaces protected by fixed automatic fire suppression systems using pressurised agents.
This test verifies whether the protected enclosure has sufficient tightness to retain the extinguishing agent for the minimum hold time required by the international standards:
NFPA 2001 and ISO 14520/ EN 15004.
At the same time, it analyses the peak overpressure and underpressure generated at the moment of agent discharge, verifying whether the enclosure has adequate pressure relief in place. This prevents potential structural damage to walls, ceilings, raised floors, doors and sensitive equipment.
Through this test, we ensure both suppression effectiveness and re-ignition prevention.
Key Aspects Evaluated During the Test
The test is performed without the need for actual agent discharge, allowing for a rigorous and safe technical evaluation.
Extinguishing agent retention capacity
Room behaviour during the pressure peak at discharge
Identification of critical leakage points that may compromise effectiveness
Technical Differentiation
As part of our technical specialisation strategy, the Retrotec certification and the technical investment made position Hestiafire as a national reference in the verification of room integrity for spaces protected by pressurised suppression systems.
Retrotec certification provides Hestiafire with internationally recognised technical capability to perform the Room Integrity Test and issue the corresponding technical certification report.
