Attenuation of Detonator Explosion in Testing Electrical Detonators

During standard testing of electrical detonators, some of them require firing likewise. In this process, very high temperature is reached and the noisy explosion of a relatively high level is heard, while parts of metal shell of a detonator are scattered in all directions. This is the reason why the testings are carried out outdoors, accompanied by necessary human and equipment protection measures, or indoors, where the detonators could be tested in a specially designed high-pressured sealed testing apparatus. Outdoors&#8217 ; ; ; areas for testing are selected to be far enough from towns and places, whereas the handling with high-pressured apparatuses is awkward and demands for more time spent in testing. Therefore we undertook to construct the open-testing apparatus, where the effective attenuation of detonator explosion could be applied. This paper gives the results obtained in usage of the constructed open-testing apparatus with the application of standard attenuation elements.
