Enclosure Integrity Test – Frequently Asked Questions

Enclosure Integrity Test – Frequently Asked Questions
Annual Enclosure integrity testing are required under British Standard (BS EN: ISO 14520) and is now routine practice at most major commercial institutions such as banks and data companies. The benefits of this are widely recognised by insurers and regulatory authorities, who require annual integrity testing.

Due to the importance of server/data rooms to all businesses, we often receive phone calls off clients requesting information in regards to their impending Enclosure Integrity Test.

The questions usually follow a similar theme:

• How do I prepare for the enclosure test?
• How are the tests undertaken?
• What disruption will we suffer during the test?

To try and place people at ease we have collated and answered the most common questions. And as always prior to visiting site we always send out our informative Fire Enclosure Checklist to help you prepare for the testing.

Enclosure Integrity Test – Frequently Asked Questions
a. Why do I need a fire enclosure test? 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.

b. How quickly can an enclosure integrity test be arranged?
Usually within a few days, however we do offer an ‘out of hours’ service which can be arranged within 24hrs.

c. How long does the enclosure test take?
The test usually takes between 1 and 2 hours. In some cases it may take longer if the room fails the enclosure test and smoke testing and remedial works are required.

d. Will the enclosure integrity test set off alarms?
No. The enclosure test is completely independent of the detection system.

e. Is the enclosure integrity test disruptive?
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 a requirement of the client.

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

g. Does air conditioning need to be switched off during the enclosure integrity test?  Recirculation (chiller) units may continue to run. Air supply/extract ducts passing into the enclosure will need to be either in damper closed mode; or, temporarily sealed.

h. Will I get a certificate if I pass the enclosure integrity test?
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.

i. What happens if the room fails the enclosure integrity test?
An inspection will be conducted 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.

j. Can remedial sealing be done at the time of the enclosure integrity test?
Yes, provided the leakage can be swiftly remedially, or temporarily, sealed. We can offer a service where we stay on site all day at a small extra cost.

k. Does APT undertake remedial sealing?
We can do this if requested, or the client can arrange remedial sealing themselves.

l. How often should the enclosure integrity test be done?
The relevant British Standard (BS EN: ISO 14520) specifies that the test should be conducted annually as part of routine maintenance and/or if the enclosure envelope is breached, i.e. by installing a new cable run/s through the wall.
