Abstract

In the paper are presented results of testing electric detonators according to New European Standards.
In order to establish real, marginal values, testing have been performed on suggested devices with extreme parameters applied.
Consequently, sensitivity on impact of bridge wire, primary and secondary explosive charge, thermal stability, resistance to water and resistance to hydrostatic pressure of electrical detonators have been measured with wider range that proscribed by the standard.
The results obtained by the research were used to evaluate reality of proposed values in New European Standards.

Keywords

testing of electric detonators; thermal stability; hydrostatic pressure stability; impact sensitivity; mechanical strentgh; European standards
