Wind Tunnel, defined by EN 54
The response time of heat-sensitive detectors can betested in the wind tunnel, defined by EN 54 part 5. The detectors are tested in an air
stream having a constant mass flow equivalent to a velocity of 0,8 m/s +- 0,1 m/s and rates of rise of air temperature up to 30 °C/min.
