Specifications |
| High Temperature Storage/Dry Heat |
The specimen shall be subjected to 125± 2oC
for 1000 hours in a thermostatic bath with out load and then stored at room temperature
and humidity for 1 to 2 hors. Thereafter, change of Vc shall be measured. |
¡µVcmA/VcmA¡Ø ±5% |
| Damp Heat/Humidity (Steady State) |
The specimen shall be subjected to 40± 20oC,
90 to 95% RH for 1000 hours without load and then stored at room temperature and humidity
for one to two hours. Thereafter, the change of Vc shall be measured. |
| Temperature Cycle |
| The temperature cycle shown below shall be
repeated five times and then stored at room temperature and humidity for 1 to 2 hours. The
change of Vc and mechanical damage shall be examined. |
