6. Performance
The test method shall be as specified in IEC 60115-1.
Standard atmospheric conditions
Unless otherwise specified, the standard range of atmospheric conditions for making measurements
tests is as follows;
Temperature
5 to 35deg C
Relative humidity 45 to 85%RH
Air pressure 86 to 106kPa
If there is any doubt about results, measurements shall be made within the following limits;
Temperature
20
±
2deg C
Relative humidity
60 to 70%RH
Air pressure 86 to 106kPa
6.1 Electrical
6.1.1 Resistance and tolerance
Method;
Refer to IEC 60115-1, Sub-clause 4.5.
Specification:
Not exceed the specified tolerance on rated resistance in para.4.1.(2).
6.1.2 Temperature characteristic of resistance
Method;
Resistance shall be measured under standard atmospheric conditions.
When the temperature reaches and is maintained at 100 deg C higher than the temperature of standard
atmospheric conditions, resistance shall be measured again. The measurement shall be made after a
period of 30 min, after each specified temperature is reached.
Specification:
Not exceed the specified temperature coefficient of resistance in para.4.1.(3).
6.1.3 Overload
Method;
A d.c. or a.c. r.m.s. voltage of 2.5 times the rated voltage shall be applied for 5 sec, and a check shall be
made to see if arcing or other damage happened. Then the resistor shall be maintained without electrical
load for 30 min after which the resistance shall be measured. However the applied voltage shall not
exceed the maximum overload voltage.
For other procedures, refer to IEC 60115-1, Sub-clause 4.13.
Specification:
Change in resistance :
±
(0.5%+0.05
Ω
)
Without damage by flash over (spark, arcing), burning or breakdown etc.
