| Abstract | Reliability Demonstration Tests (RDT) are a common procedure in reliability engineering to provide evidence of the minimum reliability achieved by a product [1]. Planning RDTs seems to be quite easy and the evaluation of the results can be done quickly based on the Binomial distribution. However, various test scenarios are conceivable for redundant systems. The tests can be carried out at component or system level. If the product is tested at system level, a distinction must be made as to whether the redundant components of the system are monitored. This results in a total of three test approaches: system test without component monitoring, system test with component monitoring and test at component level. The different test approaches have significant effects on the test setup and must therefore be considered in the planning phase of a reliability proof of a redundant system.
