Descrição: |
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.
