After gradual applying of the force specified below and keeping the unit fixed
for 10 seconds, the terminal shall be visually examined for any damage.
The unit shall be secured with its terminal kept vertical and the force
specified below shall be applied in the axial direction.
The terminal shall gradually be bent by 90 in one direction, then 90 in the
opposite direction, and again back to the original position.
The damage of the terminal shall be visually examined.
After repeated applying of a single harmonic vibration (amplitude:0.75mm,
double amplitude:1.5mm) with 1 minute vibration frequency cycle (10 Hz to
55 Hz to 10Hz) to each of three perpendicular directions for 2 hours.
Thereafter, the unit shall be visually examined.
After dipping the terminals to a depth of approxirnately 3 mm from the body
in a soldering bath of 235 5 C for 2 0.5seconds, the terminal shall be
visually examined.
After each lead shall be dipped into a solder bath of 260 5 C to a point
2.0 to 2.5mm from the body of the unit, using shielding board (t 1.5mm),
be held there for 10 1s (5 series:5 1s) and then be stored at room
temperature and normal humidity for 1 to 2 hours.

The specimen shall be subjected to 125 2 C for 1000 hours in a
thermostatic bath without load and then stored at room temperature and
normal humidity for 1 to 2 hours. Thereafter, the change of V
measured.
The specimen shall be subjected to 40 2 C, 90 to 95% RH for 1000 hours
without load and then stored at room temperature and normal humidity for 1
The following temperature cycle shall be repeated five times and then stored
at room temperature and normal humidity for 1 to 2 hours. The change of
After being continuously applied the Maximum Allowable Voltage at 85
2 C for 1000 hours, the specimen shall be stored at room temperature and
normal humidity for 1 to 2 hours. Thereafter, the change of V
measured.
