Acceleration Factors in Accelerated Life Testing
An acceleration factor is the ratio of field life to test life under a stated model, and it is what lets a six-week test stand in for ten years. Its validity depends on the failure mechanism being unchanged at the elevated stress — the assumption that, when broken, produces confident answers about a mechanism that never occurs in the field.
