Pull
Lead wire shall not cut off.
Capacitor shall not be broken.
As in figure, fix the body of capacitor, apply a tensile weight gradually
to each lead wire in the radial direction of capacitor up to 10N
(1.0kgf) and keep it for 10 ± 1 sec.

Bending
Each lead wire shall be subjected to 5N (0.51kgf) weight and then a 90° bend, at
the point of egress, in one direction, return to original position, and then a 90°
bend in the opposite direction at the rate of one bend in 2 to 3 seconds.
13 Solderability of Leads
Lead wire shall be soldered with uniform coating on the axial
direction over 3/
of the circumferential direction.
The lead wire of a capacitor shall be dipped into a methanol solution of 25wt%
rosin and then into molten solder of 235 ± 5°C for 2 ± 0.5 seconds. In both
cases the depth of dipping is up to about 1.5 to 2mm from the root of lead wires.
