European foreword
This document (EN 13763-3:2025) 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withdrawn at the latest by April 2026.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 13763-3:2002.
a) the document title has been changed from “Detonators and relays — Part 3: Determination of
sensitiveness to impact” to “Detonators and detonating cord relays — Part 3: Verification of
insensitiveness to impact of detonators, surface connectors, detonating cord relays and shock tubes”;
b) the Scope has been revised so that the document now also applies to semi-finished detonators and
electronic detonators;
c) the normative references have been updated;
d) the terminology entries 3.1 and 3.2 have been removed;
e) the Clause 4 “Principle” has been added;
f) the Clause “Apparatus” has been restructured and revised;
g) the Clause “Test pieces” is now called “Preparation of test sample”, has been revised and enlarged to
include semi-finished detonators and electronic detonators;
h) the Clause “Procedure” has been revised so that no longer a determination of the sensitiveness to
impact is carried out but only the verification of the insensitiveness to impact at a specific level;
i) the Clause “Procedure” has been enlarged to include semi-finished and electronic detonators;
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.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
A list of all parts in the EN 13763 series, published under the general title Explosives for civil uses —
Detonators and detonating cord relays, can be found on the CEN website.
Any feedback and questions on this document should be directed to the users’ national standards body.

4 Principle
During transport and use, detonators, surface connectors, detonating cord relays and shock tubes can be
subjected to impacts. Insensitiveness to impact is the ability of detonators, surface connectors, detonating
cord relays and shock tubes to not initiate when subjected to impact.
For the verification of the insensitiveness to impact, test pieces are subjected to an impact by dropping a
weight on them using either a drop hammer or an impact testing apparatus, observing whether they
detonate or deflagrate upon impact.
5 Apparatus
5.1 Adhesive paper tape, capable of sticking to the ends of a shock tube.
5.2 Drop hammer apparatus, comprising of the following components (5.2.1 to 5.2.9) as shown in
Figures A.1 to A.4.

EXAMPLE The BAM fall-hammer is a widely used example for a drop hammer.
5.2.1 Steel block, casted with base.
5.2.2 Main anvil and an intermediate anvil, made of hardened steel of type 90MnCrV8 in accordance
with EN ISO 4957:2018, Tables 4 and 5.
