Test Methods ( JIS C 5201-1 )
6.1 Direct load
Resistance to a 2.5 kgs direct load for 10 secs.
in the direction of the longitudinal axis of the terminal leads.
Twist test :
Terminal leads shall be bent through 90° at a point of about
6mm from the body of the resistor and shall be rotated through 360°
about the original axis of the bent terminal in alternating direction
for a total of 3 rotations.
6.4 Permanent resistance change when leads
immersed to 3.2 to 4.8 mm from the body in
350 °C ± 10°C solder for 3 ± 0.5 seconds
6.5 The area covered with a new , smooth
clean , shiny and continuous surface free
from concentrated pinholes.
Test temp. of solder : 245°C ± 3°C
Dwell time in solder : 2 ~ 3 seconds
6.9 Specimens shall be immersed in a bath of
trichroethane completely for 3 minutes with
ultrasonic.
7.4 Resistance change after continuous
5 cycles for duty shown below:

7.9 Resistance change after 1,000 hours
operating at RCWV with duty cycle of
(1.5 hours "on", 0.5 hour "off") in a humidity
test chamber controlled at 40°C ± 2°C
and 90 to 95 % relative humidity
7.10 Permanent resistance change after
1,000 hours operating at RCWV with duty
cycle of ( 1.5 hours "on", 0.5 hour "off" ) at
