Note 6: The average operating lifetime at room temperature is estimated by the
accelerated operation at high temperature conditions.
5.3 Failure Check Standard
After the completion of the described reliability test, the samples were left at room
temperature for 2 hrs prior to conducting the failure test at 23±5°C; 55±15% RH.
