Improvement of Sequential Tests in IEC-61124 Reliability Testing - Compliance Tests for Constant Failure Rate

摘要

An improvement of IEC-61124 in the field of a sequential probability ratio test (SPRT) is proposed. The current standard does not provide a proper solution for modern industry's needs, and the test plans are not up-to-date with the knowledge in the area of sequential tests. The advantages of the proposed version are reflected by the efficacy and accuracy of the tests, the wider range of the ready to use test's parameters, and available data regarding the test's characteristics. The proposed version is a significant improvement over the existing one. The changes will extend the use of SPRT and this standard. The proposal for updating the standard has been accepted to the work-plan of TC-56 of IEC.
