Transmission of detonation at a distance test

Detonation by Influence or Sympathetic Detonation Tests (Transmission of Detonation at a Distance Test) (Aptitude a transmettre la detonation a distance, Essai or Coefficient de self-excitation, Essai, in Fr) (Detonationsiibertragung Probe ox Schlagweite Probe, in Ger) (Determinacion de la sensibilidad a la iniciacion por simp ana, in Span) (Distanxa di eaplosione persimpatia, prova, in Ital) include the following methods Booster Sensitivity Test(qy) b)Four-Cartridge Test]Sce PATR 2510(PB 1612 i(1958),p Ger 521... 

Transmission de dytonatiqn k distance (Transmission of Detonation at a Distance), known as Aptitude k traosmettre la detonation a distance (Ability to Transmit the Detonation at a Distance). See Ref 24, E140-L. Same as Detonation by Influence, Sympathetic Detonation or Gap Test... 

Transmission de la detonation d distance (Transmission of Detonation at a Distance), also known as Coefficient de self-excitation (Coefficient of Self-excitation) or Aptitude b tronsmettre lo ddtonation b distance (Capability, to Transmit the Detonation at a Distance). This test is known in the USA as Gap Test, Sympathetic Deto-notion Test or Detonation by Influence Test. The French modification of the test described by M dard (Ref 8, pp 342-44) was earlier described by Dutour (Ref 6). This test is described in Vol 3 of Encycl, p C3SX) as Coefficient de Self-excitation (CSE) and gap values for several expls at different densities are given... 

One can also study the influence of the mass of the donor charge on the distance at which complete transmission of detonation to a given acceptor charge may occur. Then the tests are conducted in such a manner that the distances dso or dioo at which transmission of detonation occms in 50% or 100% cases, respectively, are determined for each mass of the donor charge. On the basis of the data, the dependence of the distance ( 50 or if 100) upon the mass of the explosive charge (Mj) as shown in Figure 2.30 m be obtained. 

The maximum distance at which the complete transmission of detonation is observed in three consecutive trials is report as a test result.
