Test equipment function: The equipment is designed to test and record opening and closing moment of Floor Spring continuously in double directions from 0 degree to 180 degree opening and from 0 degree to -180 degree opening. 1. Floor spring is installed on the test door; 2. The servo motor open the test door from 0° to o the maximum opening angle or 180° under speed of 1° /s, and record the opening force and opening degree during the process; 3. Then, the motor reverses and slowly releases the door leaf, and the door close from 180 ° to 0° under the action of the door closer,Record the closing force and degree of the closing process; 4. The opening / closing process come out "force vs angle" curve (as shown in Figure 1); 5. Calculate the data and generate the performance test report of closing force value according to EN 1154:1997+A1:2006,ANSI/BHMA A156.4:2019 (As shown in Figure 1) and test method and report for QBT2698-2016;; 6. set another open direction and repeat the test |
