Advanced Accelerated Life Testing Analysis

Learn ALT Models, Analysis and Test Design

D521 explores advanced concepts and applications for quantitative accelerated life testing data analysis, including tests with multiple stresses or time-dependent stresses.

The course presents concepts and software tools that you could use to help your organization:

  • Significantly reduce the test time required to obtain reliability metrics for a product, which can result in faster time-to-market, lower product development costs and improved designs.
  • Understand and quantify the effects of stress (or other factors) on product life.
  • Design accelerated tests that will be the most effective to achieve desired objectives.
