As an important part of reliability engineering，reliability test is one of the important means to measure whether products meet the reliability requirements. GJB899A "Reliability Appraisal and Acceptance Test" standard gives a series of statistical test schemes，which mainly involve the fix-time censored test scheme and the sequential censored test scheme. In this paper，the principles of these two types of test schemes are analyzed，the determination methods of the test schemes are defined according to the required parameters of the test schemes，and the verification method of reliability indexes is given. Combined with application examples，it is analyzed and explained for guiding engineers to choose the appropriate reliability test scheme according to the reliability requirements of the tested products，which can effectively help developers and orderers to carry out reliability tests.
