Pressure Test specialises in providing Room Integrity Test services across the UK. We are based in Wokingham in Berkshire and also have a facility in Leeds in Yorkshire. This gives us the ability cover all areas of the UK.
Integrity Testing is essential for anyone who uses a gas suppression system. For more information on our Room Integrity Testing service please call our team today.
Room Integrity Testing of enclosures is a method of determining how long fire suppressant agents take to descend to a given level, without releasing the agent itself.
When a fire is detected, gaseous fire suppression systems release a gas agent into the enclosure to reduce oxygen levels and thereby suppress the fire.
The main standards in the UK for room integrity testing are BS EN 15004 & ISO 14520. It is recommended that an enclosure is tested upon installation, when a change to the area is made or annually thereafter.
These rules apply to any size or kind of room fitted with gaseous fire suppression systems. If you do not carry out these tests regularly, you risk having a building with an ineffective gas suppression system, which is a fire hazard. It might also invalidate your building insurance.
Our engineers will install a large fan rig, usually in a doorway. Next, we’ll temporarily seal all openings into the area being tested before switching on the fans. Gradually increasing and decreasing the air pressure in the room will allow us to monitor the differential air pressures. These pressure changes are recorded, which will then allow us to determine the amount of fire retardant gas that is escaping.
If your room doesn’t pass then we will recommend remedial work is carried out. Before this can be undertaken we must first establish where the gas is leaking by carrying out further tests.
These tests can include:
Smoke Testing
This will provide a visible indication of the problem areas, as the smoke will flow through the openings. In less extreme situations, we can use devices known as ‘smoke pencils’ to complete the task.
Depressurisation
This is done by pressurizing the whole building, which forces air out through any gaps or cracks. Reducing the pressure will cause draughts as the air rushes back into the room, indicating where the air is escaping.
Thermography
We use an infrared camera to detect where the hottest and coldest parts are in the room, which can help us identify where the gasses are escaping.
