Building Envelope test and integrity test for FM200 Clean Agent Rooms

Building envelope testing and integrity testing for FM200 clean agent rooms involve assessing the integrity of the room's structure and ensuring that it effectively contains the FM200 clean agent in the event of a fire suppression discharge. The purpose of these tests is to verify that the room is properly sealed to prevent the escape of the clean agent, thereby maximizing its effectiveness in extinguishing fires while minimizing damage to the surrounding area.

The effectiveness of a protected enclosure depends on its ability to retain an extinguishing agent at the appropriate concentration level for 10 minutes in order to suppress a potential fire. To achieve this, the enclosure must be properly sealed to prevent agent leakage. Compliance with relevant standards requires conducting a room integrity test after the installation is completed. One efficient method of ensuring compliance with ISO 15004 is to pressurize the room with a blower fan system while also performing air sealing. This allows for the detection of air leakage paths through a localized smoke test, which can then be sealed. A final room integrity test is conducted to ensure compliance with applicable standards.

The sealing requirements for FM-200, a specific extinguishing agent, are more stringent compared to inert agents due to its unique characteristics.
