Performance Test System of Floor Spring
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 doorclose 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 dataand 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
