Determination of critical parameters in mechanical testing methods of electrical detonators according new drafts of european standards

In the paper are presented results of testing electric detonators according to New European Standards. In order to establish real, marginal values directed by the standard, testing have been performed on suggested devices with extreme outer conditions applied. Consequently, sensitivity on impact of bridge wire on primary and secondary explosive charge have been measured with wider range than proscribed by the standard. Also, construction strenght of electrical detonators have been determinated in same manner. The results obtained by the research were used to evaluate reality of proposed values in New European Standards.
