Introduction to Quantitative Accelerated Testing, Applications, Benefits and Drawbacks
Accelerated testing can be divided into two areas: qualitative accelerated testing and quantitative accelerated
life testing. In qualitative accelerated testing, the engineer is mostly interested in identifying failures and failure modes without attempting to make any predictions as to the product's
life under normal use conditions. In quantitative accelerated life testing (QALT), the engineer is interested in predicting the life characteristics of the product (such as MTTF, B10 life,
etc.) at normal use conditions from data obtained in an
accelerated life test. This tutorial introduces the
basic principles and concepts behind quantitative accelerated life
testing data analysis.
Key Words: Accelerated
Testing, QALT, Life vs. Stress
