Abstract
The article considers a task related to the general approach to determining the random error in determining the endurance limit by accelerated methods. Based on the conducted analysis, it was shown that in the calculation of the accuracy of accelerated methods for determining the endurance limit, it is necessary to separately determine the systematic and random components of the total error. It was also proposed to determine the random error of accelerated methods for determining the endurance limit using a general statistical approach. At the same time, it is proposed to find the accuracy of the assessment of the endurance limit itself, depending on the specific test scheme of one or another accelerated method.
