Hot gas velocities for other sizes are possible by calculating according to EN 13384–1. Maintain the hot gas temperature at 50+ % of the test temperature, and the flow rate at 100+ % of the value but not less than 0,2 m/s given in Table 2, until equilibrium or 6 h. Equilibrium is deemed to exist when the rate of rise of the temperature at the hottest point on the test assembly or structure does not exceed 1 K per 30 min up to hot gas temperatures of 250 °C and 2 K per 30 min for higher hot gas temperatures. During the test phase, the ambient temperature shall not vary by more than 5 K. Record the temperatures after firing the test assembly until the temperatures have reached their maximum. Check the free movement of the draught regulator flap. SIST EN 16475-3:2016

Fix the draught regulator in the closed position. Draw air from the tube until there is an underpressure of (10 ± 1) Pa. Record the flow rate. Measure the underpressure to an accuracy of ± 1 Pa. Measure the volume flow to an accuracy of 5 %. Repeat for two other samples of the draught regulator of this size. Repeat for each size of draught regulator. 5.2.3 Test results Record the volume flow for each test. Calculate the average volume flow for each size of draught regulator. 5.3 Additional criteria for chimney operation 5.3.1 Adjustability of the draught regulator 5.3.1.1 Test Assembly Use the test assembly of 5.2.1. 5.3.1.2 Test procedure Adjust the draught regulator to the lowest declared setting. Draw air from the tube until the draught in the tube causes the draught regulator to open. Record the difference in the draught from the setting. Repeat this procedure for draught settings on the draught regulator of 5 Pa steps. SIST EN 16475-3:2016
