Pretreatment:
Capacitor is stored at 85 ±2°C for 1 hour and then placed at room
condition1 for 24 ±2 hours before measurement.
With the termination in its normal position, the specimen is held
by its body in such a manner that the axis of the termination is
vertical; a tensile force of 10 N is applied to the termination in the
direction of its axis and acting in a direction away from the body
of the specimen.
Lead wire or capacitor body shall not

break.
With the termination in its normal position, the specimen is held
by its body in such a manner that the axis of the termination is
vertical; a mass force of 5 N is then suspended from the end of
the termination. The body of the specimen is then inclined within
a period of 2 to 3 seconds, through an angle of approximately 90°
in the vertical plane and then resumed to its initial position over
the same period of time; this operation constitutes one bend.
One bend immediately followed by a second bend in the opposite
direction.
