Degradation AF vs. Stress Plot

The AF vs. Stress plot shows the acceleration factor as a function of stress level. The acceleration factor is determined by dividing the product’s life under normal operating conditions by its life at an accelerated stress level. For example, if the acceleration factor is 2 at an accelerated stress level of 350 K, then the product’s life at 350 K is expected to be half of its life at the specified use stress level.
