CONDITION & REQUIREMENT
After being placed in a chamber with +85 ± 2 ℃ for 1000 hours and then being
placed in natural condition for 2 hours, then measure.
⇒ To be satisfied Table 1.
After being placed in a chamber with -55 ± 2 ℃ for 1000 hours and then being
placed in natural condition for 2 hour, then measure.
⇒ To be satisfied Table 1.
After being placed in a chamber within +90 to 95％ R. H. at +60 ± 2 ℃ for
1000 hours and then being placed in natural condition for 2 hour, then measure.
⇒ To be satisfied Table 1.
After being kept at room temperature, the resonator shall be placed at temperature of
-55 ℃. After 30 minutes at this temperature resonator shall be immediately placed at
temperature of +85 ℃. After 30 minutes at this temperature resonator shall be
returned to -55 ℃ again. After 100 above cycles, the resonator shall be returned to
room temperature for at least 2 hour, then measure.
⇒ To be satisfied Table 1.
Resonator shall be measured after 3 times random drops from the height of
1 m on wooden floor.
⇒ No visible damage and the measured values shall meet Table 1.
Resonator shall be measured after being applied vibration of amplitude to 1.5㎜ with
10 to 50㎐ band of vibration frequency to each of the perpendicular directions for 2
hours.
⇒ No visible damage and the measured values shall meet Table 1.
Resonator is soldered onto the center of PCB which is laid on the 2 small supporters
spaced 90mm. PCB deflected to 1mm below from horizontal level by the pressing
force with 20x10.R10 stick. The force is supplied for 1 second, 5 times repeatedly.
Velocity of pole for press : 0.5mm/sec.
