Mechanical test:
The quartz crystal unit shall be subjected to normal atmospheric
conditions for 1hr before being tested.
Dropping Test:
The Units are measured for its frequency and resistance in
accordance with Table1 & without mechanical damage,after
allowing the crystal to fall freely.
From 75 cm of height 3 times on the firmed wood.
Vibration Test:
The Units are measured for its frequency and resistance in
accordance with Table 1&without mechanical damage afer
subjectiong to 2hrs of vibration with 0.75mm amplitude with 10~55Hz
frequency sweep 20 times.
