5) Insulation(between epoxy resin and soldered terminals)
5-1 Dielectric withstanding voltage: AC 100V for one second.
5-2 Insulation resistance : Above 100 MΩ at DC 500V.
6) Climatic tests
6-1) Damp heat(under loading)
DC 1 mA current shall be applied to the test samples in the temperature of 40℃ and relative humidity of 95%RH for 1,000 hours. After being stored in room temperature and humidity for one hours, the change ratio of R25 shall be within ±2% of the initial value.
6-2) Cold
Test samples shall be exposed in air at -30℃ for 1,000 hours. After being stored in room temperature and humidity for one hours, the change ratio of R25 shall be within ±3% of the initial value.
6-3) Rapid change of temperature
One cycle of the change of temperature shall be proceeded in the order of the following conditions.
.At -20℃, for 5 minutes.
.Room ambient temperature, for one minute.
.At + 70℃, for 5 minutes.
.Room ambient temperature, for one minute.
100 cycles of change of temperature shall be applied to the test samples. After being stored in room temperature and humidity for one hour, the change ratio of R25 shall be within ±2% of the initial value.
7) Mechanical characteristics
7-1) Robustness of terminations
* Tensile to horizontal direction
Hold the thermistor body so that lead wire shall be horizontal. After 1 kg loading weight was applied to the lead wire horizontally for 10 seconds, there shall be no visible damage.
7-2) Free fall
After three times natural fall to a maple board from 75cm high, there shall be no visible damage.
