A New Start-Up Demonstration Test

The commonly known consecutive successes total failures (CSTF) start-up demonstration test procedure is improved to a total successes consecutive successes total failures (TSCSTF) procedure. Accordingly, a unit under test is accepted when either a total number of successful tests, or a specified number of consecutive successes of tests are observed before a total number of failures; otherwise the unit is rejected. The waiting time until termination (the length of the set of tests) of the new procedure is evaluated. A correct choice of parameters (e.g. the number of successes required for acceptance, the total number of failures causing rejection) using the new procedure may yield a shorter waiting time than that of the relevant CSTF procedure.
