Introduction
During usage, detonators, surface connectors and detonating cord relays can be subjected to different
shocks or impacts. This test deals with the ability of detonators, surface connectors and detonating cord
relays to resist the shocks or impacts they could be exposed to under specified conditions.
prEN 13763-3:2021 (E)
1 Scope
This document specifies methods for determination of the sensitiveness to impact for plain detonators,
electric detonators, non-electric detonators, electronic detonators, surface connectors, detonating cord
relays and shock tubes used with electronic and non-electric detonators.
This document applies to explosives for civil uses.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in prEN 13857-1:2021 and the
following apply.
3.1
drop height
distance between the lowest part of the striking head of the drop weight and the uppermost part of the
percussion cylinder
3.2
drop hammer
device that allows a controlled drop of a weight to hit the test subject
Note 1 to entry: Drawings can be found in Annex A.
3.3
ignition system
electrical resistance heating wire surrounded by an incendiary material
4 Principle
The test piece is subjected to an impact using specific equipment and weights dropped on the test piece
at specific heights, checking whether explosion occurs. The mean height is calculated using the Bruceton
method, where it is determined the level of stimulus at which there is a 50 % probability of obtaining a
prEN 13763-3:2021 (E)
positive result. The minimum height is determined by the Bruceton method at which a positive result is
obtained.
