Introduction
During usage on site, the insulation on the leading wires of electric detonators, electronic detonators and
the plastics tubing for shock tube for non-electric detonators and electronic detonators can be subjected
to abrasive forces when drawn over rough surfaces. The plastics material is worn away gradually by
abrasion. This document consists of a test method to determine the ability of leading wire
insulation/shock tube to resist the abrasive forces likely to be experienced in normal use.

1 Scope
This document specifies a method for determining the resistance to abrasion of plastics used as insulating
material for leading wires of electric detonators and electronic detonators or used as base material for
the tubing of shock tube for non-electric detonators and electronic detonators.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

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 subjected to abrasion by an abrasive surface, moving at a specified speed, while a
specified load is applied. For leading wires, the time taken for the insulation to be penetrated is
determined. After the abrasion the functioning of the shock tube is tested by immersion in water.
5 Apparatus
5.1 Abrasion test apparatus, as shown in Figure 1, compromising the following main components.
5.1.1 Steel or brass rotor, with the dimensions as shown in Figure 2, with a perimeter of
(453 ± 2) mm.
1
5.1.2 Abrasive strips , three pieces approximately 10 mm × 145 mm each, made of grinding steel as
specified in Annex A.
5.1.3 Load, to be applied to the test piece through the hinged arm (see 5.1.4).
5.1.4 Hinged arm, made of steel or brass as shown in Figure 3 and with the capacity to carry a load of
(8,35 ± 0,05) N.
5.1.5 Pulley, diameter (70 ± 1) mm, with a capacity to carry a tensile load of (8,1 ± 0,5) N.
5.1.6 Motor, capable of maintaining a constant speed of rotation whatever load is applied to the rotor.
NOTE A DC motor with an output power of at least 500 W and with a separate speed control can be used.
5.1.7 Rotor, capable of reaching its specified speed of rotation 0,6 s after starting.
NOTE This requirement can be verified by two electrodes about 20 mm apart, each adjusted to give electrical
contact to the tips of the rotor during rotation. The electrodes are connected to a digital counter, counting elapsed

of Electronics, Box 857, S-501 15 Borås, Sweden, Tel.: [phone], Fax: [phone], Email: [e-mail].

time between the pulses from the two electrodes when they are touching the tips of the rotor. Comparison is made
between the elapsed time during a continuous run at the specified speed and the elapsed time 0,6 s after start. First
the rotor is rotated manually to an appropriate position in order for a tip of the rotor to reach the second electrode
after 0,6 s.
The electrodes can also be used for calibrating the specified speed of rotation, e.g. by measuring the time for one
revolution. In this case only one electrode is required.
5.1.8 Digital timer with relay output, capable of:
— being set to a predetermined time in the range of (0 to 10) s ± 0,1 s;
— being started (triggered) when the hinged arm is lifted by the test piece;
— automatically stopping the rotor when the predetermined time has elapsed (only required for shock
tube testing);
— automatically stopping the rotor when electrical contact is made between the leading wire and the
abrasive strip or the rotor (only required for leading wi
