Server Room Integrity Test

Server Room Integrity Test

Server Room Integrity Test

If you have a server room that’s protected by fire extinguishment it is required to have an annual Server Room Integrity Test. Protected enclosures such as Data Centres, Server Rooms and Laboratory’s all need to be tested on an annual basis, given the potential consequences of downtime due to fire damage.

Approved standard BS ISO 15004 states that an server room integrity test be undertaken prior to the handover of the enclosure, and annually thereafter. It also states that an integrity test should be undertaken if the room has received new works i.e. new penetrations have been formed through the room envelope to allow for new data/electrical installations; in this instance another room integrity test should be undertaken immediately after the installation works have been completed.

To allow the gaseous fire suppression system to work properly the room must be sufficiently airtight to retain an extinguishing concentration for a specified period after discharge; this is usually10 minutes unless an extended discharge has been designed into the system. If the protected room cannot hold the extinguishment for the minimum retention period, then the fire may reignite causing further damage to critical asset.

Fire Damage to Server Rooms

Blower Door Integrity Testing

The blower door Integrity Testing, method provides a means of predicting the retention time without the need to release the extinguishing gas. The test methodology is in accordance with the general requirements specified in NFPA 2001, BS EN 15004 and the BFPSA Code of Practice for Gaseous Extinguishing Systems. The fan is positioned within the enclosure access doorway. Pressure and de-pressure airflow measurements are taken, from which the leakage characteristics of the enclosure are established. The predicted retention time is calculated from these leakage characteristics and the enclosure and extinguishing system.

A Blower Door Fan System Undertaking an Integrity Test

Room Integrity Testing can be undertaken to all types and sizes of enclosures, from large data centre’s to small server rooms. In each case we carry out the necessary calculations prior to the test, and use high powered UKAS calibrated blower door fan systems with integrity testing software to determine results immediately upon completion of the room integrity test. Our experienced engineers continually ensure that the room integrity testing is clean and non-disruptive and the room can carry on its normal working operations – there is no requirement for shutdowns to your critical assets.

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.

We understand the importance of protecting your critical assets and as a result our server 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 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 server room integrity test pass.
