The functioning of the thrust ventilation system can also be tested afterwards in various ways:

COLD SMOKETEST

The simplest test is using cold smoke. A smoke machine smoke production is set up at the most critical location. This will fill the area for a predetermined time with smoke. Subsequently, an assessment will be made as to whether the existing ventilation system is capable of discharging the smoke sufficiently and within the stipulated time. In addition, cold smoke can be used to show whether dead unventilated corners are present. The disadvantage of this test is that it is not possible to assess thermodynamic influences.

FULL SCALE TEST

The most reliable test is with the help of real cars.

However, this test is very expensive as well as dangerous and can also cause damage to the building. The thermodynamic influences are then fully present. The results of a cold smoke test compared to a car fire can therefore differ.

WARM SMOKE TEST

Finally, testing can still be done with the Hot Smoke Test.

The thermodynamic influences are fully visible but the test will not cause any damage to the building since a clean alcoholic fire is being used, but special precautions must be taken, which in turn makes this test not quickly feasible.
