Purpose: Previous work regarding reliability testing has focused on accelerated life testing, leading to a lack of information on non-accelerated life testing; however, it is a proper choice when testing time is not a constraint. Methods: Therefore, the design process of the non-accelerated testing is proposed, including selecting the essential component to test, defining target life expectancy and main stress factors, designing testing profiles, and determining the number of test items and testing periods. Especially, this paper provides the guideline with which the stress levels and the test profile can be designed based on the MIL-STD-810 standard. Results: We show that the vibration testing profile can be designed by applying the Miner-Palmgren rule to the given MIL-STD-810 profile. The temperature range of interest was directly derived from the standard. Conclusion: This paper presents the design guideline of the non-accelerated life testing case where the test item is an essential component of defense systems and the main stress factors are temperature and vibration.
