(T.C.R.)
TEST METHOD
Measure resistance at
+25°C or specified room
temperature as R1, then
measure at –55°C or
+155°C respectively as R2.
Determine the
temperature coefficient of
resistance from the
following formula:
Formula
R2–R1
T.C.R. = ------------------------- ×10⁶ (ppm/°C)
R1(t2–t1)
Where
t1=+25°C or specified room temperature
t2=–55°C or +155°C test temperature
R1=resistance at reference temperature in ohms
R2=resistance at test temperature in ohms
ACCEPTANCE STANDARD
Refer to table 2
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 ΔR/R(%) after one more hour.
±(1.0%+0.05Ω)
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 ΔR/R(%).
±(1.0%+0.05Ω)
No visible damage
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 ΔR/R(%).
±(2.0%+0.05Ω)
No visible damage
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.
