What if I Fail My Room Integrity Test

What if I Fail My Room Integrity Test

One common question we often get asked is “What if I Fail My Room Integrity Test”. If your Integrity Test result is less than the required 10 minute retention time then it will result in a test failure. However; thereafter a smoke survey inspection can be carried out to identify all major air leakage paths prior to the undertaking of the remedial sealing works.  An air leakage report is issued detailing the results and any recommendations in an easy to follow format. This allows you to undertake remedial sealing works on the day of the test to achieve a test pass.

A Room Integrity Test with a Blower Door System 


At APT we understand the importance of protecting your critical assets and as a result our room integrity testing process is as rigorous and as complete as any other within the industry, using our extensive knowledge of testing Data Centres, Server Rooms and ITU you can be safe in the knowledge that the testing is being undertaken by a UKAS accredited testing laboratory.

We undertake room integrity testing using the latest UKAS calibrated blower door systems. The blower door fan is latched into a fully adjustable cloth door panel that fills the opened door frame space. the enclosure test is undertake by running the calibrated fan at different pressures, thus generating pressure into the protected enclosure from the outside space. By monitoring the pressure differential between the external space to the protected room a series of readings is taken from 10-60Pa on pressurise and depressurise and data inputted to our integrity software; together with added information such as the protected height and the type and weight of gas, i.e. FM200, FE25, Argonite etc.  Once the information is logged into the computer the software can then work out the descending interface height hold time, or mixing concentration result.

If the protected room is air tight, then a pass should be easily achievable. If the room has too many air leakage paths (and the retention time is less than 10minutes) then it will result in a test failure. To achieve a pass the room will require a smoke test to highlight the air leakage paths, after the smoke survey further sealing works can be undertaken along with a final retest to achieve a room integrity test pass.

If you have a protected enclosure that requires a room integrity test, please contact us at: info@airpressuretesting.net or call Darren direct on 07775623464. We undertake testing throughout London, England and Wales.

If you fail your room integrity test don’t panic, APT’s highly trained and experienced Enclosure Testing Engineers will be able to locate the problem areas and identify where air is leaking out of the building by walking around the test enclosure with a localised smoke puffer, pencil checking the most common problem areas first. Some of the most common air leakage paths within the building envelope are:

  • around cracks or penetrations within the masonry/.plasterboard walls.
  • around pipe chases and cable trays where they penetrate the perimeter boundaries of the protected enclosure
  • around the inside perimeter at the floor and ceiling junctions.
  • Around porous block-work walls – this can be remedied by painting and ensuring the mortar joints are full.
  • around the entrance door reveals – door sweeps this can be remedied by installing drop seals, weather stripping around jambs.
  • around window frames and glazing.
  • Around various penetrations within the ceiling void such as underside of doorways.
  • Around poorly installed air conditioning dampers.

Once we have undertaken the smoke test and located the air leakage paths, we can collate and issue a detailed air leakage report which can be passed on to the fire sealing team. It’s also worth noting that the smoke won’t cause any damage to the building and/or equipment.

By combining our fan testing equipment, we blow the smoke out through any penetrations in in the enclosure envelope; this makes the air paths far more visible. Smoke leaking from the enclosure can also be seen outside, and photographed to provide a record of any external leakage paths.

Pressurised Smoke tests are ideal for identifying both generic and smaller more torturous areas of air leakage.
