Why Do Room Integrity Testing?

Why Do Room Integrity Testing?

We often get asked why do room integrity testing? there are two critical reasons why you need to undertake the testing, the first is It’s a legal requirement and the second is you may invalidate your buildings insurance if you do not have up to date room integrity certification.


The Relevant Standards

BS5306, ISO 14520 and BS EN 15004 – 1, 2008 all require a gaseous system (any system) to have its integrity checked annually. The equipment should be designed specifically for this and it should be regularly calibrated at least once a year. An Integrity test should be conducted in accordance with BS5306, ISO 14520 (BS EN 15004 – 1, 2008) or NFPA 2001 and at a minimum this should be conducted annually.

When Should Room Integrity Tests be done?

An room integrity test should be performed immediately after a system has been installed and routinely every year thereafter. Any alteration such as changing a door, putting a cable/s in or even replacing equipment can affect the rooms (enclosures) gas holding ability (Integrity), routine servicing of equipment will not reveal this, so an Integrity Test should be carried out after any alteration and the annual testing dates adjusted to follow annually thereafter.

How is the Room Integrity Tests Carried Out

A portable fan is temporarily installed in the doorway via a collapsible panel. The fan then both pressurises and depressurises the room. The results are then fed into the specialist software which then works out the retention time. If the enclosure attains results in excess of 10 minutes then the protected enclosure will pass the test, anything under 10 minutes and it will result in an integrity test failure due to excessive air leakage. If it fails the test APT can help you to locate the excess air leakage paths via smoke testing.
