Enclosures protected by gas suppression systems require adequately sealing to contain the concentration of gas within the space for the required minimum retention time against an allowable leakage rate.

To evaluate whether an enclosure has sufficient air tightness we can perform a Room Integrity Test by using the internationally recognised Retrotec Fantestic Software. A calibrated and certified axial flow fan is fitted into the door frame and used to pressurise and depressurise the entire room.

By running the calibrated fan at a certain speed, thus generating pressure into / from the space, and by monitoring the pressure differential within and external to the room, that flow rate is actually measured, data inputted to software together with the volume of the enclosure, protected height and the fill weight of gas (FM200 / FE25 / Novec 1230 or the Inert gasses such as IG55, IG541 and IG100) and a descending interface height hold time, or mixing concentration result is obtained.

If, however, a room can hold the gas above a specified height for descending interface or above 85% of the design concentration for 10 minutes or more, then a Pass result is recorded and the enclosure can be certified for a further 12 months. If, however, the retention time is below 10 minutes then our experienced Test Engineers will carry out a full survey identifying as many leakage paths as possible, so sealing works can begin and return visit booked in. Testing is required each year in accordance to most International standards to re-certify the room and the gas suppression performance, and may be a requirement of the client’s insurance company to revalidate the protection provided to the space.

Platinum Fire Suppression Ltd have over 25 years combined experience in Integrity Testing and can offer a remedial sealing package to ensure an enclosure passes on the return visit if required.
