Test methods/conditions
260 °C, 10 s:
Each lead shall be dipped into a solder
bath having a temperature of 260 ±5 °C
to a point 2.0 to 2.5 mm from the body of
the specimen, be held there for 10 ±1 s
and then be stored at room temperature
and normal humidity for 1 to 2 h.
The change of V
and the specimen shall be visually
examined.
IEC 60068-2-21, test Ua1
After gradually applying the force
specified below and keeping the unit
fixed for 10 s, the terminal shall be
visually examined for any damage.
Force for wire diameter:
