-20℃~70℃

Crystal Frequency & Resistance will be tested under the following conditions,

Unless extra requirments:

standard temperature(25±2℃) after heat balance.

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.
