Test methods/conditions
CECC 42 000, test 4.16
The specimen shall be subjected to:
a) dry heat at UCT, 16 h
b) damp heat, 1st cycle:
c) cold, LCT, 2 h
d) damp heat, additional 5 cycles:
Then the specimen shall be stored at
room temperature and normal humidity
for 1 to 2 h.
Thereafter, the change of V
measured. Thereafter, insulation resis-
tance R
to CECC 42 000, test 4.8 at V = 500 V.
IEC 60068-2-14, test Na, LCT/UCT,
dwell time 30 min, 5 cycles
The specimen shall be subjected to
40 ±2 °C, 90 to 95% r. H. for 56 days
without load / with 10% of the maximum
continuous DC operating voltage V
Then stored at room temperature and
normal humidity for 1 to 2 h.
Thereafter, the change of V
measured. Thereafter, insulation resis-
tance R
to CECC 42 000, test 4.8 at V = 500 V.
IEC 60068-2-20, test Ta,
method 1 with modified conditions for
lead-free solder alloys: 245 °C, 3 s:
After dipping the terminals to a depth
of approximately 3 mm from the body
in a soldering bath of 245 °C for 3 s, the
terminals shall be visually examined.
55 °C, 93% r. H., 24 h

The inspection shall be
carried out under adequate
light with normal eyesight or
with the assistance of a
magnifier capable of giving
a magnification of 4 to
10 times. The dipped sur-
face shall be covered with
a smooth and bright solder
coating with no more than
small amounts of scattered
imperfections such as
pinholes or un-wetted or
de-wetted areas. These
imperfections shall not be
concentrated in one area.
