A new procedure for determining the acceptance or rejection of a system that undergoes a start-up demonstration set of tests is\r\npresented. It is a generalization of the recently introduced CSDF model (consecutive successes distant failures). According to the\r\nnew total successes consecutive successes total failures distant failures (TSCSTFDF) procedure, a unit is accepted when either a\r\ntotal number of successful tests or a specified number of consecutive successes are observed before a total number of failures or\r\nthe occurrence of near failures which are too close to each other.The practical advantage of this new procedure is the significant\r\nreduction in the expected number of required tests together with improved second-order statistics (standard deviation).
