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 90ꢂ in one direction, then 90ꢂ in the
opposite direction, and again back to the original position.
The damage of the terminal shall be visually examined.

Mechanical
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.
Vibration
Approximately 95% of
the terminals shall be covered
uniformly with new solder
After dipping the terminals to a depth of approxirnately 3 mm from the body
in a soldering bath of 235ꢁ5ꢂC for 2ꢁ0.5seconds, the terminal shall be
visually examined.
Solderability
After each lead shall be dipped into a solder bath of 260ꢁ5ꢂC to a point
2.0 to 2.5mm from the body of the unit, using shielding board (tꢋ1.5mm),
be held there for 10ꢁ1s (5 series:5ꢁ1s) and then be stored at room
temperature and normal humidity for 1 to 2 hours.
