Accelerated Testing Technology. Volume II. Handbook of Accelerated Life Testing Methods.

摘要

The report, in two volumes, is devoted to an investigation into the state-of-the-art of methods for reducing the time and expense associated with life testing, particularly as it relates to parts. The areas investigated are divided into accelerated testing and more powerful statistics. The accelerated tests treated in the report are tests at stresses higher than nominal design levels applied either singly or in combinations at constant, progressively increasing, or increasing by steps, stress levels. The more powerful statistical approaches found to be pertinent are those using prior information distribution-dependent methods and distribution-free methods. Volume one, prepared in handbook format, gives an assessment of advantages and limitations of the present available methods for reducing test time and expenses and presents in compact, but complete form, the instructions for using the methods which represent the state-of-the-art of accelerated life testing. Volume two presents the methodology used in performing the study, explains the evaluation systems used on the methods reported in the literature, establishes the criteria for inclusion of a method in Volume one, and highlights to useful methods developed as well as those which show promise for future development.
