An outline of the total successes consecutive successes total failures consecutive failures (TSCSTFCF) start-up demonstration procedure is presented. 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 both a total number of failures and any run of specified length of failures; otherwise the unit is rejected. The length of the set of tests is of interest. It has been shown that a correct choice of parameters (e.g. the number of successes required for acceptance, the length of a run of failures causing rejection) may yield a significant shorter waiting time than previously known procedures.
