5.7 Resistors shall be clamped in the trough
of a 90° metallic V-block and shall be tested at
AC potential respectively for 60 +10/ -0 secs.
7.4 Resistance change after continuous
5 cycles for duty shown below:
5.5 Permanent resistance change after the
application of a potential of 2.5 times RCWV
for 5 seconds
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

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 secs.
