Abstract
The article proposes a solution to the problem of the variety of physico-mathematical models of EEE-storage life test acceleration by implementing a method based on the analysis of the results of accelerated tests in different modes. The objects of the study are reed relays. The article presents the main physico-mathematical models used for calculating the acceleration factor when simulating storage, as well as sets forth a description of a method for comparing these models. According to this method, the product is tested in various modes and, in accordance with the procedure for accelerated storage life testing based on the prediction of parameter time-dependent degradation, the storage period is estimated. Then, for each model, the storage period estimate is obtained for normal climatic conditions together with the standard deviation. The model with the least standard deviation is considered to be the most suitable for the tested type of product. The physico-mathematical models of the acceleration of reed relay failure mechanisms during storage were studied with the help of this technique; the most suitable is the reverse exponential model.
