EN 13763-15:2004 (E) 5 Introduction General When fired, the explosive charge of detonators must provide a pulse of sufficient energy to initiate the explosive or a detonating cord/shock tube, with which they a

26、re intended to be used. In the test procedure described in this document, the output performance of a test piece is compared with a reference having known characteristics and mass of charge. This document describes two tests: an underwater initiating capability test and a functioning test at low and

27、 high temperatures. Underwater initiating capability This test is based on the principle that the detonation of an explosive charge under water generates a spherical shock-wave and a volume of gas, which expands and then collapses as the bubble rises through the water. The shock-wave and the volume

28、of gas bear a finite relationship to the energy released. Thus, by measuring: the shock-wave pressure; and the time interval between the shock-wave pressure peak and the first collapse of the gas bubble, and calculating the parameters proportional to: equivalent shock energy; and equivalent bubble e

29、nergy, the energy output of the test detonators can be compared with the energy output of the reference detonator to which the manufacturer claims equivalence. Functioning test at high and low temperatures This test checks that the energy output of the detonators does not vary when they are fired at

30、 high and low temperatures, by firing detonators in contact with aluminium witness plates at ambient, high and low temperatures and comparing the depths of indentations made in the plates. EN 13763-15:2004 (E) 6 1 Scope This document specifies a method of determining the equivalent initiating capabi

31、lity of detonators. This document also specifies a functioning test (after storage) at high and low temperatures. This document is not applicable to surface connectors or detonating cord relays. 2 Normative references The following referenced documents are indispensable for the application of this d
