    TEST CONDITION
    ①Setting-up time: 20 sec/cycle
    ②Load torque:
    - 4.90 N･m (50kgf･cm)
    - 6.86 N･m (70kgf･cm)
    - 8.83 N･m (90kgf･cm)
    ③Temperature: 23℃±2℃
    ④Angle for measuring the closing time: 90° → 0°
    ⑤Radial force: nothing
    ⑥Closing time after durability test:
    - 4.90 N･m → 2.5 sec or more
    - 6.86 N･m → 2.5 sec or more
    - 8.83 N･m → 2.0 sec or more

TEMPERATURE CHARACTERISTICS
