Climatic test
1) Dry Heat
After the test samples were exposed in air at 90±1ºC for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
2) Damp heat
After the test samples were exposed in the humidity of 95% at 40 ±2ºC for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
3) Cold
After the test samples were exposed in air at -30 ±1ºC for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
4) Loading
After DC 1mA current was applied to the test samples in the temperature of 40 ±2ºC and the humidity of 95% for 1,000 hours, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
5) Change of temperature
One cycle of the change of temperature shall be carried out in the order of the following conditions.
Room ambient temperature. (Initial value) At -25 ±3ºC, for 30 minutes.
Room ambient temperature, for 3 minutes.
After the 100 cycles of this process, the change ratio of the rated zero-power resistance shall be within ±1% of the initial value.
