Overview of Accelerated Life Test Designs

When product reliability at normal use conditions is high, you can test the product under conditions that are more severe than normal so that failures occur more quickly. You can use this accelerated failure data to predict product reliability at normal use conditions.

Such a test is called an accelerated life test (ALT).The factors that are set at higher than normal use levels are called acceleration factors. The models for accelerated life tests are typically nonlinear models. For details about nonlinear models, see “Nonlinear Models” in the “Nonlinear Designs” chapter.

The ALT Design platform creates and evaluates designs for situations involving one or two acceleration factors (and their ...
