Short time overload
The resistance variation shall be
within±(0.5% + 0.05ohm) and there
Shall be no mechanical breakage




 		JIS-C-5202 5.5
Apply DC voltage 2.5times the rated
Voltage for 5 seconds
 The leave at room temperature for 30
Minutes then measure MAX overload
Voltage 0.50W - 700V (DC)

Insulation resistance
10,000M ohm or more		JIS-C-5202 5.6  in V-BLOCK
Lay the resistor on 90° angle metal V
Block apply 500VDC between resistor
Lead and V block for one Minute And
Measure

Voltage endurance
The resistance variation shall be
within±(0.5% + 0.05ohm) and there shall
Be no mechanical breakage
 		JIS-C-5202 5.7
Icy the resistor on the 90° angle metal V
Block and apply reamed AC voltage for
One Minute. Test voltage

Intermittent overload
Resistance variation shall be
Within ±(0.50% + 0.05ohm) 		JIS-C-5202 5.8
Apply AC voltage 4 times the rated voltage for 1 second and rest for 25 seconds and Repeat this cycle for 10000±200times leave resistor 30 minutes at room temperature after test and measure
Maximum voltage for intermittent
Overload.0.50W - 700V(AC)
 
Terminal strength		 
Resistance variation shall be within
±(0.5% + 0.05ohm) also there
Shall be on mechanical breakage
Pull test apply 2.5kg force to the lead in the direction of lead axisfor30±5 seconds.


Heat resistively
Against soldering

Resistance variation shall be within ± (0.25%+0.05ohm) also there
Shall be on mechanical breakage
JIS-C-5202 7.10
Dip the lead in to a solder bath having a
Temperature of 350ºC ± 10ºC up to 4±0.8mm from the body of the resistor  and hold it for 3±0.5seconds leave the resistor at room temperature 3 hours after ,then Measure

Load life test
The variation of the resistance
Shall be within ± (1.5%+0.05ohm)
Also there shall be no mechanical
Breakage
JIS-C-5202 7.10
In the constant temperature chamber having Temperature70ºC ± 2ºC,apply rated Dc voltage for 1.5hour and shut voltage for 0.5 hour and repeat this cycle for 1000 hours,leave in room temperature hour after test, then measure
