Door Fan Test for Gas-extinguishing Systems
Details
Descriptions
Gas-extinguishing systems make special requirements during the planning phase because, in order to evaluate the effectiveness of the gas-extinguishing facility, it is important to know how leak proof the room to be protected actually is. For this reason, VdS has been offering for some years so-called "Door Fan Test for Gas-extinguishing Systems " to measure the airtightness of a room. The principle with the door fan test is to produce overpressure and underpressure in a room and simultaneously measure the air flow.
Based on these measurements, Door Fan Test for Gas-extinguishing Systems can be determined how large the leakage area is in the room. This value influences the composition and holding time of the intended extinguishing gas concentration. With the Door Fan Test for Gas-extinguishing Systems , cost and time-intensive flooding tests can be kept to a minimum.
