identical text or by endorsement, at the latest by April 2026 and conflicting national standards shall be
withdrawn at the latest by April 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 13763-5:2003.

1 Scope
This test method specifies a test method for the verification of the resistance to cutting damage of leading
wires and shock tubes of leading wires of electric and electronic detonators as well as shock tubes of non-
electric detonators, surface connectors and electronic detonators.
This document does not apply to detonating cord relays and electronic initiation systems.

4 Principle
During use, the insulation on the leading wires and the plastic tubing of shock tubes can be drawn over
sharp edges cutting into the material. In case of leading wires, this could cause short cuts and in case of
shock tubes, this could cause misfires.
For the verification of the resistance to cutting damage, a test piece is drawn over a cutting edge whilst
being subjected to a load in longitudinal direction. For leading wires, it is observed whether an electrical
contact is made between the conductor wire of the test piece and the cutting edge. For shock tubes, the
test pieces are subsequently immersed in water and initiated afterwards; it is checked whether the test
piece initiates.
