Book excerpt: Excerpt from Investigation of Detonators and Electric Detonators The indirect method of determining the mechanical effects of ex plosives, or the energy developed by them, approximates practical conditions and offers an accurate means for determining the relative efficiency of detonators and electric detonators in bringing about complete detonation of commercial high explosives. As all direct methods of testing detonators are therefore dependent on the indirect method for verification, the first experiments under taken were to determine the relative strength of electric detonators indirectly by comparing the energy developed by different commercial explosives when fired with different grades of electric detonators. Afterwards tests were made by determining the relative strength of electric detonators by direct means, and a test was devised that, although not entirely satisfactory, gave results that approximated more closely those established by the indirect tests.
