Introduction
During usage on site, the insulation on the leading wires of electric detonators, electronic detonators and
the plastic tubing of shock tube to be used in non-electric detonators and electronic detonators can be
subjected to cutting forces when drawn over a sharp edge which cuts directly into the material. This
document consists of a test method to determine the resistance to cutting damage of leading wire
insulation/shock tube likely to be experienced in normal use.

1 Scope
This document specifies a method for determining the resistance to cutting damage of the plastic
materials used in insulation of leading wires of electric detonators, electronic detonators and the tubing
of shock tube for non-electric detonators and electronic detonators, when drawn over a sharp edge under
specified loading conditions.
This document is applicable 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 apply.
4 Principle
The test piece is drawn by a motor over the tungsten carbide cutting edge and subjected to a gradually
increasing load. When the spring balance reads a specific load, the apparatus is stopped, and the test piece
removed. For leading wires, a record is made whether there has been an electrical contact between the
test piece conductor and the tungsten carbide cutting edge. For shock tubes the test pieces are stored in
water after the test and are initiated within 1 h. A record is made whether or not the shock tubes initiates.
5 Apparatus
5.1 Cutting damage apparatus
The cutting damage apparatus shall incorporate the basic principles shown in Figure 1 comprising of a
tungsten carbide edge, two pulleys, an electric motor, electrical device and a spring balance.
