For exhaust fans always use the values for negative pressure chimneys. Regulate the rate of rise of the hot gas temperature to achieve the test temperature defined in EN 1443, with an average increase of 50 K per min. Normal production sizes are limited to a diameter of 200 mm. Hot gas velocities for other sizes are possible by calculating in accordance with EN 13384-1. SIST EN 16475-2:2017

+ 50) °C for a period of 30 min. After 25 min at 1 000 °C, determine the highest temperature on the test corner, using an IR-thermometer. If the position of this temperature is more than 5 cm different from the position found during the heat stress test, terminate the thermal shock test, and move the thermocouple to the new position. Repeat the thermal shock test with a new exhaust fan mounted (if necessary) in exactly the same angular position. After 30 min turn off the hot gas generator. Continue to record the temperatures on the test assembly until the temperatures have reached their maximum. NOTE The relevant product standard may require to run the test with a positive pressure chimney and a high positive pressure chimney for sootfire condition. 5.2.6.2 Test results Record all temperature values as specified in 5.2.4. Record any instance where the maximum temperature exceeds the allowed values. For the purpose of determining temperature rises on the exhaust fan and on enclosures and structures, such temperatures shall be related to the ambient air temperature. Continue to record the temperatures on the test assembly until the temperatures have reached their maximum. SIST EN 16475-2:2017
