Accelerated Temperature Humidity Testing Using the Arrhenius-Peck Relationship

Humidity Testing can be used to accelerate the aging of products that are affected by ambient humidity levels. Increasing the humidity above the normal use level humidity can cause defects or failures to occur in shorter times than what would be observed in the field.  Humidity testing is most commonly performed along with testing at elevated temperature so that the resulting acceleration factor is affected by both humidity and temperature. The Acceleration Factor (AF) which is the ratio of the life at use conditions to the accelerated life at test conditions for temperature humidity testing is given by the following Arrhenius-Peck equation:

Acceleration Factor
