PERFORMANCE AND QUALIITY ACCEPTANCE |
TEST METHOD |
|
Resistance to temperature coefficient |
±300PPM/℃
|
R – RO 106
RO T- T0
R = Measured resistance(Ω)at T T ℃ Ro = Measured resistance (Ω)at To To ℃ T = Measured test temperature(℃) To = Measured base temperature( ℃)
|
|
Short time overload |
±(1%R + 0.05ohm) Shall be no mechanical breakage
|
AC or DC voltage 10times the rated Voltage or 600v, Get the lower voltage. At 5 seconds. |
|
Insulation resistance |
﹥500MΩ
|
Lay the resistor on the 90° angle metal “V” Block applies DC 500V voltage for One Minute. |
|
Voltage endurance |
±(0.5%R + 0.05ohm) Shall be no mechanical breakage
|
Lay the resistor on the 90° angle metal “V” Block applies AC 1000V voltage for One Minute. |
|
Terminal strength |
Shall be no mechanical breakage |
Pull test apply 20N force to the lead in the direction of lead axis for 30±5 seconds. |
|
Heat resistively against soldering |
±(1%R + 0.05ohm) Shall be no mechanical breakage
|
Dip the lead in to a solder bath having a temperature of 350℃ ± 10℃ up to 3±0.05mm from the body of the resistor and hold it for 3.5±0.5seconds leave the resistor ,at room temperature 1 hours after ,then Measure.
|
|
Load life test |
±(5%R + 0.05ohm) Shall be no mechanical breakage
|
In the constant temperature chamber 70℃ ,apply rated voltage for 1 hour and shut voltage for 0.5 hour and repeat this cycle for 1000 hours, |
|
Solder ability |
≥95% |
Dip the lead in to a solder bath having a temperature of 260℃±5℃. Time:5± 0.5seconds. |
|
Humidity load test |
≤± (5% R+ 0.1ohm) Shall be no mechanical breakage
|
In temperature chamber 40℃±2℃,relative humidity 90 – 95%,Apply rated voltage 1.5hour and shut voltage 0.5 hour repeat this cycle for 1000 hours, leave in room temperature for 1 hour after test, |
|
Vibration |
Shall be no mechanical breakage
|
Set a resistor at the vibration table and vibrate 10HZ—55HZ 10HZ/s. with 1.5mm amplitude in 1 min. when the change of frequency shall be completed uniformly. The vibration shall apply to 3 directions, vertical and horizontal to the axis of resistor each for 3h. |
|
Incombustibility |
Shall be no mechanical breakage
|
Resistance by ordinary fire 15 seconds stops for 5 seconds, so loop 5 times. |
