Appendix Description - Test Methods
| Item | Description |
|---|---|
| Thermal dissipation coefficient | Refer to GB/T 6663.1. Measure and record the zero power resistance at temperature Tb (typically 850.1). For leaded thermistors, clamp with a fixture 25mm 1.5mm from the body. Place in a test box (volume 1000 times thermistor volume) with static air at 255, ensuring at least 75mm clearance from walls. Connect test circuit with high impedance voltmeter and ammeter (accuracy >1%). Adjust current ITH until UTH/ITH is within 5% of the zero power resistance at Tb. Calculate =(UTH ITH)/(Tb-25)mW/. Note: Results can vary due to testing environment and methods. |
| Thermal time constant | Refer to GB/T 6663.1. Measure zero power resistance at Tb=(358.152)K, Ta=(298.152)K, and Ti (calculated as Ti:=Tb-(Tb-Ta)X0.632). Installation method is same as for . Use high impedance voltmeter and ammeter (accuracy >1%), resistance meter (accuracy 1%). Close contact AA, adjust ITH until UTH/ITH is 60%-80% of zero power resistance at Tb. Close contact BB and time from reaching zero power resistance at Tb until reaching zero power resistance at Ti. The time elapsed is the thermal time constant. |
| Maximum impulse capacitance Cmax | Capacitor CT discharges through a series fixed resistor and thermistor. Charging voltage is 180/375 V, corresponding to (110/230+U)2. Perform 1000 discharge cycles. Test environment temperature between 15 and 35, maintained within 2 of the starting temperature. |
