(1) Short Time Over Load Test
(2) Dielectric Withstanding Voltage
(3) Temperature Coefficient Test
At 2.5 times of the rated voltage. ( If the voltage exceeds the maximum load voltage, the maximum
load voltage will be used as the rated voltage ) applied for 5 seconds, the resistor should be free
from defects after the resistor is released from load for about 30 minutes
Short Time Overload Voltage =
The change of the resistance value should be within ± 0.25 % + 0.05
The resistor is placed on the metal V Block. Apply a Table I dielectric withstanding between the
terminals connected together with the block for about 60 seconds.
The resistor shall be able to withstand without breakdown or flashover.
Test of resistors above room temperature 100° C 2° C ( Testing Temperature 115° C to 130° C ) at
the constant temperature silicon plate for over 5 minutes. Then measure the resistance value.
The Temperature Coefficient is calculated by the following equation and its value should be within
the range of requested.
