Integrity Testing Server Rooms

Integrity Testing Server Rooms
Initially the enclosure integrity testing was introduced as an environmentally friendly alternative to discharge testing following the phase out of halon extinguishant under the Montreal Protocol on ozone depletion. It is applicable to all sizes of enclosure and all extinguishing gases, including Argonite, Inergen, Proinert, IG55, FM200, FE25, HFC 227ea, FE25, Novec 1230 and CO2. Air Pressure Testing provides the necessary Room Integrity Testing to the required NFPA 2001 or ISO 15004 methodologies.

We have undertaken enclosure testing on all types and sizes of enclosure, from server rooms in offices to hospital intensive care units. In each case we carry out the necessary volumetric calculations prior to the test and use calibrated test fan systems along with laptops running complaint integrity testing software to determine results immediately upon completion of the server room enclosure test.

We ensure that our enclosure integrity testing is clean and non-disruptive, using a door mounted fan(s) to measure leakage flow. Work may continue as normal in the room during the test. An immediate result is obtained for the total room leakage and consequent extinguishant retention time. If this is below that required by the Standard, a detailed inspection is carried out to identify all major leakages for remedial sealing. A formal report is issued detailing the results and any recommendations. The failure report should be retained for regulatory authority/ insurer’s reference. If you fail the test – Air Pressure Testing can undertake the remedial works for you; and due to the importance of these areas; specialise in out of hour’s remedial works as we understand the impact/cost of closing down areas such as turbine rooms etc. to minimise disruption.

In the event of a failed enclosure integrity test we can quickly locate and record the air leakage paths. We can quickly provide enclosure air leakage reports highlighting the worst air leakage paths so remedial works can be quickly targeted.

The server room integrity tests passes we can issue the test reports incorporating all necessary data test information and certification within a few days of the enclosure integrity test.

What Rooms Usually Require Enclosure Integrity Testing
All rooms protected by fire extinguishment require Enclosure Integrity Testing – rooms such as Computer Server Rooms, Plant Rooms, and Laboratory’s. Given the potential consequences of fire damage and down time for such critical areas/equipment, it is essential that an integrity test is undertake before handover of the enclosure and annually thereafter, or if the protected rooms enclosure has received new works resulting in new penetrations through the rooms envelope.

For a fire suppression system to work, the room must have sufficient integrity to retain an extinguishing concentration for a specified period after discharge. Failure to do so may cause the fire to reignite causing further damage. As this is the predominant cause of failure, the British and International Standard (BS: ISO14520) requires an enclosure integrity test be conducted on system installation and thereafter at annual intervals.

Air Pressure Testing have undertaken hundreds of enclosure integrity tests on varying room types from comm’s room/s to massive power station turbines enclosures; and have the experience to help you achieve a test pass at the first attempt. We are one of a very few companies that fully understand the theory behind extended discharge tests and are able to undertake testing to enclosures where extended discharge tests are required.

Annual integrity testing is required by the BFPSA and its now carried out by all major commercial institutions such as banks and data companies. It is also worth noting that your buildings insurance may be negated if you don’t undertake the annual data room integrity test.

Server Room Testing – Frequently Asked Questions

  1. Why do I need a fire enclosure test on my server room?

A – The test is a requirement of the British Standard for gaseous fire extinguishing systems – BS EN:ISO 14520. Most fire insurers will require evidence that the test has been conducted and the result is satisfactory.

  1. How quickly can an server room integrity test be arranged?

A – Usually within a few days.

  1. How long does the enclosure test take?

A – Usually between 1 and 2 hours.

  1. Will the server room integrity test set off alarms?

A – No. The enclosure test is completely independent of the detection system.

  1. Is the server room integrity test disruptive?

A – No. It is only necessary to stop access to the room for 10-15 minutes. Personnel can continue to work in the room. The enclosure test can be paused if immediate access becomes required.

  1. Does equipment such as servers need to be switched off during the enclosure integrity test?

A – No the equipment can keep running.

  1. Does air conditioning need to be switched off during the enclosure integrity test?

A – Recirculation (chiller) units may continue to run. Air supply/extract ducts passing into the enclosure will need to be either dampered closed or will be temporarily sealed.

  1. Will I get a certificate if I pass the server room integrity test?

A – It will be issued within a few days. This should be retained for possible inspection by the authorities/insurers. A summary certificate can be issued at the time of enclosure test if required.

  1. What happens if the room fails the server room enclosure test?

A – We can carry out an inspection to identify leakage paths for remedial sealing. These will be pointed out at the time of the enclosure test and a plan included in the report. It is recommended that a retest be conducted after remedial action to confirm the adequacy of the retention time.

  1. Can remedial sealing be done at the time of the server room enclosure test? – Yes, provided the leakage can be swiftly remedially, or temporarily, sealed.
  2. Can APT undertake remedial sealing?

A- Yes we can do this if requested or the client can arrange remedial sealing themselves.

  1. Do you supply any literature to help us prepare for the enclosure test?

A – Yes, we supply all our clients with an easy to follow checklist to help you prepare for the test.

  1. How often should the enclosure integrity test be done?

A – The relevant British Standard (BS EN:ISO 14520) specifies that the test should be conducted annually as part of routine maintenance.

If you have a protected enclosure that requires an integrity test or you think you have a problem in terms of your enclosure construction – please contact us at: as we can send across our air sealing checklist to help you prepare for the server room enclosure test. We can also offer a sealing service should it be required.
