27、ing basket, from the edge of abench, or down an unloaded borehole. This test assesses the ability of detonators, relays and surface connectorsto withstand being dropped without detonating.1 ScopeThis European Standard specifies methods for checking that a detonator, relay or surface connector will n

Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. F

The shortest wire length/shock tube length delivered fr
33、om the manufacturer shall be used. 50assemblies are tested according to 6.2 and 50 according to 6.3.In case of delay detonators, select those in the series which contain the longest delay element.For plain detonators, test 50 detonators of each specific type, having the same materials, charges, dime
34、nsions andconstruction, by the guided drop test only.5.2 Surface connectors and relaysSelect 50 assemblies of each specific type, having the same materials, charges, dimensions and construction.6 Procedure6.1 Test conditionsIn the free-fall test, the assemblies shall be tested as delivered from the
35、manufacturer. Both alternatives describedshall be tested, and neither of them can replace the other. The test shall be carried out at ambient temperature.6.2 Free-fall drop test for detonators (excluding plain detonators)Fix the clamp and release mechanism at a vertical height of (5 0,02) m above a
36、solid concrete floor. Theassembly is fixed in the clamp in such a way that the detonator faces downwards, and the height is measuredbetween the floor and the lowest point of the assembly. Drop the assembly so that any part may hit the floor first.Repeat the test on 50 test pieces.Record the number o
37、f detonators not detonated during the test.After testing, all assemblies not detonated during the test shall be fired one at a time with the manufacturersspecified series firing current for the specific type, or in accordance with the manufacturer instruction for otherdevices. Record the number of d
38、etonators which do not detonate during the function test.6.3 Guided drop test for detonatorsFix the metal tube vertically so that the lower end is positioned centrally and (10 1) mm above the steel plate. Thedeviation from the vertical shall not exceed the outer diameter of the tube.In the case of e
39、lectric detonators or shock tube detonators, cut the leading wires or the shock tubes (2 0,5) mmfrom the crimp or connection to the assemblys casing.Drop the detonator from the top of the tube so that:a) the base of the detonator hits the steel plate first, andb) the top of the detonator hits the st
40、eel plate first.Repeat the test on 25 detonators in each alternative a) and b).Record the number of detonators not detonated during the test.SANS 53763-11:2008This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .EN 13763-11:2003 (E)76.4 Drop test
41、for surface connectors and relaysFor surface connectors, remove the housing and cut off the leading wires or the shock tubes. Drop the detonator asdescribed in 6.3.For relays, drop them without their housing as described in 6.3. If the relay housing cannot be disassembledwithout destroying the relay
42、, a free-fall drop test, as described in 6.2, shall be carried out instead of the guided droptest.Record the number of test pieces not detonated during the test.7 Test reportThe test report shall conform to EN ISO/IEC 17025. In addition, the following information shall be given:a) the temperature du
43、ring the test;b) the length of the leading wires or shock tubes on the samples;c) the number of detonators/connectors/relays not detonated during the drop tests;d) description or photographs of the arrangement of the detonator immediately before the drop;e) the number of detonators/connectors/relays
