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+A1:2019
