The regulation (UNI 10877, ISO 14520, UNI EN 15004) provides the verification of integrity of the local fire-fighting system for both new and existing system.
Excessive air infiltration may compromise the maintenance of the level of extinguishant concentration for a time of 10 minutes, as required by the regulation (UNI EN 15004) regarding class A fuels.
This period, called permanence time, allows the extinguishant to act, guaranteeing extinguish fire.
Through the blower door test it is possible to evaluate the actual degree of air loss and to determine if a local is able to retain the extinguishant for the right time.
The Blower door test is essential to guarantee the effectiveness of self-extinguishing systems and it must be performed on annual maintenance plan in environment with high technological concentration for example: ced room, server room or for rooms that contain documents or easily flammable materials such as: archives, library, laboratories…
SCANTEC has proper certified equipment, as skilled and competent technicians who perform the blower door test to verify the retention of gaseous extinguish.
