Environment factor assessment based on degradation data and reaction rate model

This paper presents a method to assess the environment factor, which is used to discount data at accelerated operating condition into data at normal condition. This method combines degradation data with reaction rate model, considers the interior relationship between environment stress and product´s degradation rate, which not only cut down the amount of work, but also can predict environment factor at some other stress. An approach based on the ratio of performance degradation rate is proposed to validate the results, and the effectiveness of proposed method is demonstrated by the example of carbon-film resistors.
