Room Integrity Testing

Room Integrity testing and the RIBA Plan of Work

What is Room Integrity Testing?

Room Integrity Testing is a specialist type of air tightness test provided by Stroma Built Environment for rooms which are protected by gaseous fire suppression systems. We will check the ability of the enclosure to retain an effective concentration of gas, which is critical to the safe operation of the system. It is a requirement to conduct a Room Integrity Test upon installation and as a minimum once a year thereafter.

Room Integrity Testing services – Why choose Stroma Built Environment?

Stroma Built Environment’s expert testers have experience of testing all types and sizes of enclosure, from server rooms in offices to gas turbine halls in power stations. The benefits of our approach are widely recognised by insurers and regulatory authorities.

Our Room Integrity Tests deliver:

There will be little disruption to normal working practices

All testing carried out to the required BS EN 15004 or NFPA 2001 methodologies

All necessary volumetric calculations completed prior to the test, to deliver an immediate onsite result

In the event of failure, we locate and record air leakage sites using localised smoke testing

We provide a full report, incorporating all test data, air leakage diagnosis and air leakage certification

If required, we can arrange for any necessary remedial air sealing

Room Integrity Tests generally take one and a half hours to complete. Stroma Built Environment will utilise a variety of approved test equipment including variable speed fans, expandable door panels, pressure gauges and a dedicated portable computer. A full report is provided at the conclusion of the test, incorporating all test data, air leakage diagnosis and certification.

The importance of Room Integrity Testing

A Room Integrity Test predicts how long fire suppressant agents take to descend to a given level in the room without having to release the gas itself. The room is sealed and the air pressure is tested with door fan and sensor equipment. The data generated is then processed using specifically designed computer software, in compliance with the National Fire Protection Association (NFPA) and BS EN 15004. The software predicts the time period that the suppression agents will be held in the test area at any given height. A retention time of 10 minutes is the minimum period for which the suppressant agents are required to be retained.

The test is a requirement of the British Standard for Fixed Firefighting Systems – BS EN 15004. It is needed when a gaseous system is installed and should be performed annually thereafter. It should also be performed if any modifications to the room take place. Most fire insurers will require evidence that the test has been conducted and the result is satisfactory.

Preparing for a Room Integrity Test

Equipment within the room can remain on for the duration of the test. In terms of air conditioning systems, recirculation units may also continue to run. Air supply/extract ducts passing into the enclosure will need to be either dampered closed or will be temporarily sealed.
