A reliability validation and evaluation method of linear separation devices was presented in this paper. Based on blast impact dynamics principle, the critical charge weight equivalent conversion relationship between cylinder and flat in up-and-down method test was put forward. Furthermore, the reliability evaluation problem was successfully transformed into a problem of parameter hypothesis checking in this method. The experiment results indicated that the validation and evaluation of lower limit of combustion reliability for linear separation devices with high reliability level can be accomplished, via the small sample of success or failure data of plate experiments in a low level of stimulus.
