Introduction
Non-electric detonators, electric detonators, electronic detonators, plain detonators, detonating cord
relays and surface connectors might be accidentally dropped from a loading basket, from the edge of a
bench, or down an unloaded borehole. This test assesses the ability of detonators, relays and surface
connectors to withstand being dropped without detonating.
prEN 13763-11:2021 (E)
1 Scope
This document specifies methods for determination of resistance to damage by dropping unto a hard
surface for non-electric detonators, electric detonators, electronic detonators, plain detonators,
detonating cord relays or surface connectors.
This document is applicable to explosives for civil uses.

the number of test pieces that did not explode during the functioning test after dropping shall be
recorded.
