Formula
Temperature
Coefficient of
Resistance
(T.C.R.)
Measure resistance at
+25°C or specified room
temperature as R
1
, then
measure at –55°C or
+155°C respectively as R
2
.
Determine the
temperature coefficient of
resistance from the
following formula:
T.C.R. = ------------------------- ×10

Thermal
Shock
At –55±3°C for 2 minutes and at +155±2°C for 2 minutes as one cycle. After 5
cycles, the specimen shall be stabilized at room temp.
Measure the resistance to determine
Δ
R/R(%) after one more hour.

Low
Temperature
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
Δ
R/R(%).

Short
Time
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
Δ

Insulation
Resistance
Place the specimen in the jig and apply a rated
continues overload voltage (R.C.O.V) for one
minute as shown.
Measure the insulation resistance.
