TEST CONDITION
①Setting-up time: 15 sec/cycle
②Load torque:
- 1.27 N･m (13kgf･cm)
- 1.96 N･m (20kgf･cm)
③Temperature: 23℃±2℃
④Angle for measuring the closing time: 70° → 0°
⑤Radial force: nothing
⑥Closing time after durability test: 1.5 sec or more
After the damper is stabilized at room temperature for 1 hour or more, the closing time is measured using TOK in-house device.
