This European Standard was approved by CEN on 29 September 2025.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

European foreword
This document (EN 13763-9:2025) has been prepared by Technical Committee CEN/TC 321 “Explosives
for civil uses”, the secretariat of which is held by UNE.
This European Standard shall be given the status of a national standard, either by publication of an
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withdrawn at the latest by April 2026.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 13763-9:2003.
EN 13763-9:2003:
a) the document title has been changed from “Detonators and relays — Part 9: Determination of
resistance to bending of detonators” to “Detonators and detonating cord relays — Part 9: Verification
of resistance to bending of detonators”;
b) the Introduction has been removed;
c) the Scope has been revised to clarify the covered and not covered explosives;
d) the normative references have been updated;
e) the terminology entry 3.1 has been removed;
f) the Clause 4 “Principle” has been added;
g) the Clause “Apparatus” has been revised;
h) the Clause “Test pieces” is now called “Preparation of test sample” and has been enlarged to include
electronic and semi-finished detonators and to provide revised specifications for the marking of the
test pieces for the bending test that was formerly part of the “Procedure” clause;
i) the Clause “Procedure” has been revised and now contains the specifications for the two types of the
bending test and a functional test (7.3) has been added;
j) the Clause 8 “Expression of results” has been added;
k) the Clause “Test report” does no longer require conformity with EN ISO/IEC 17025 and the
information to be provided has been revised and enlarged;
l) the former Annex A “Range of applicability of the test method” has been removed;
m) the Annex ZA has been updated;
n) the Bibliography has been added and lists EN ISO/IEC 17025:2017.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.

1 Scope
This document specifies a test method for the verification of the resistance to bending of detonators.
This document applies to electric detonators, non-electric detonators, plain detonators, semi-finished
detonators and electronic detonators.
This document does not apply to detonating cord relays, surface connectors, leading wires, shock tubes,
coupling accessory and electronic initiation systems.

4 Principle
During use, detonators can be subjected to bending during the loading of boreholes. Bending of a
detonator could cause inadvertent initiation or misfire.
For the verification of the resistance to bending, a test piece is subjected to a bending force by clamping
one end of it and attaching a weight at the other end. Two types of tests are performed, one where the
test piece is clamped at the base and another one where the test piece is clamped at the top. It
