RATED VOLTAGE:
The DC or AC (rms) continuous
working voltage corresponding to
the rated power is determined by
the following formula:
V=√(P X R)
Where
V=Continuous rated DC
or AC (rms) working voltage (V)
P=Rated power (W)
R=Resistance value (X)

TEST METHOD
Measure resistance at
+25°C or specified room
temperature as R

, then
measure at –55°C or
+155°C respectively as R

.
Determine the
temperature coefficient of

Operation
Place the specimen in a test chamber maintained at –65 (+0/–5)°C. After one hour
stabilization at this temperature, full rated working voltage shall be applied for 45
(+5/–0) minutes. Have15 (+5/–0 ) minutes after remove the voltage, the specimen
shall be removed from the chamber and stabilized at room temperature for 24 hrs.
Measure the resistance to determine
ΔR/R(%).

Overload
Apply 2.5 times of rated voltage but not exceeding the maximum overload voltage
for 5 seconds. Have the specimen stabilized at room temperature for 30 minutes
minimum.
Measure the resistance to determine
ΔR/R(%).
±(1.0%+0.05Ω) for 1% tol.
±(2.0%+0.05Ω) for 5% tol.
No visible damage
Insulation
