– What is Integrity Testing? –
Pressure Test’s engineers do their very best to ensure the integrity testing procedure does not interfere with normal daily operations. The test usually takes one hour per enclosure and is repeatable at short notice. In some instances, when an enclosure fails the test initially, remedial work can be carried out and a re-test can be performed during the same site visit.
Integrity testing is an environmentally friendly procedure. The testing process entails a door fan unit being fitted into a doorway of the protected enclosure, using expandable door panels that fit most dimensions and measures. The fan speed and air flow replicate the size of the hole or holes in the enclosure. Then, by varying the fan speed our engineers can generate a variety of pressure and flow metrics. The integrity test also measures the total area of all gaps in the enclosure, through which extinguishing agent could escape. This data is then utilised to determine whether the enclosure complies with current NFPA and BSI regulations.
Since 2006, NFPA and BS (ISO and EN) standards have stipulated that integrity testing must be undergone by all such enclosures once a year or more frequently should the enclosure change in any way. Failure to gain a pass certificate in the specified time frame could invalidate your insurance.
– What Do the Results Mean? –
To ensure the results of your integrity test are absolutely clear, Pressure Test provides a detailed post-test analysis report. The report highlights areas for improvement and indicates whether pressure relief is advisable.
If Your Enclosure Passes the Integrity Test
A Pressure Test engineer will issue a pass certificate to satisfy insurance requirements if your enclosure passes the integrity test. This certificate is valid for one year; however should subsequent changes be made to the enclosure that could affect its integrity (e.g. modifications to the enclosure or upgraded equipment) you must book a re-test. You can book your next annual test with Pressure Test by giving us a call today.
If Your Enclosure Fails the Integrity Test
It is necessary an enclosure undergoes remedial work in the instance of a failed integrity test. Once this is complete you should then book a re-test to ensure the correct safeguarding of your facility and to validate its insurance position.
