1 Scope
This document specifies a method for the verification of the transfer capability of surface connectors,
detonating cord relays and coupling accessories.
In case of coupling accessories, the document applies to non-electric detonators, electronic detonators
and surface connectors where the shock tube is equipped with a coupling accessory and to shock tubes
equipped with a coupling accessory.
This document does not apply to electric detonators, plain detonators, semi-finished detonators, and
electronic initiation systems.

4 Principle
Surface connectors, detonating cord relays and coupling accessories are used to transfer the shock wave
from one shock tube to one or more shock tubes, from a detonating cord to one or more detonating cords
or from a detonating cord to a shock tube.
Coupling accessories are not explosives but they are often sold as part of a non-electric detonators,
surface connectors or shock tubes.
For the verification of the transfer capability of a surface connector, a detonating cord relay or a coupling
accessory, the corresponding explosive article(s) is/are connected to a test piece. Either the test piece or
one explosive article connected to the test piece is then initiated and it is observed whether the test piece
successfully transfers the shock wave to the other connected explosive article(s).
5 Apparatus
5.1 Shock tubes, as specified in accordance with EN 13763-1:2025, 4.7.1.7, for the surface connector
to be tested.
5.2 Means of initiation, for the surface connector to be tested as specified in accordance with
EN 13763-1:2025, 4.7.1.4.
5.3 Detonating cords and a detonator, for testing detonating cord relay test pieces. The detonating
cords shall be the ones that may be used for the tested detonating cord relay as specified in accordance
with EN 13763-1:2025, 4.8.1.6. One detonating cord shall have a length ≥ 450 mm (donor cord) and the
other(s) shall have a length ≥ 350 mm (acceptor cords), plus the length needed for connecting the
detonating cords to the detonating cord relay. The detonator shall be as specified as means of initiation
for the detonating cord in accordance with EN 13630-1:2025, 4.1.4.
5.4 Detonating cord and a detonator, for testing coupling accessory test pieces. The detonating cord
shall be the one that shall be attached to the shock tube using the coupling accessory as specified in
accordance with EN 13763-1:2025, 4.3.1.4 (for non-electric detonators), 4.4.1.4 (for electronic
detonators), 4.7.1.4 (for surface connectors), or 4.9.1.4 (for shock tubes), as applicable. The detonating
cord shall have a length ≥ 450 mm plus the length needed for connecting the detonating cords to the
shock tube. The detonator shall be as specified as means of initiation for the detonating cord in
accordance with EN 13630-1:2025, 4.1.4.
5.5 Adhesive paper tape, capable of being used to cover the open ends of a shock tube.
5.6 Adhesive tape, made from paper, plastic or natural fibre.
5.7 Witness plate, made from aluminium designated EN AW-6082 in accordance with
EN 573-3:2019+A2:2023, Table 6, with a length of (50 ± 10) mm, a width of at least 50 mm and a
thickness of at least 10 mm.
5.8 Length measuring device, capable of being read to the nearest 1 mm for lengths up to 2 m.

6 Preparation of test samples and test pieces
Select 25 test pieces of the surface connector, the detonating cord relay or the coupling accessory to be
tested.
