European foreword
This document (EN 13631-14:2025) 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withdrawn at the latest by April 2026.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 13631-14:2003.
EN 13631-14:2003:
a) the document title has been changed from “High explosives — Part 14: Determination of velocity of
detonation” to “Explosives for civil uses — Explosives for blasting, boosters and explosive
substances — Part 14: Determination of velocity of detonation of explosives for blasting”;
b) the Scope has been revised to clarify the covered and not covered explosives;
c) the normative references have been updated;
d) Clause 4 “Principle” has been revised and enlarged;
e) Clause 5 “Apparatus” has been updated and enlarged, especially, to include an alternative velocity of
detonation measuring equipment;
f) Clause 6 “Test pieces” is now called “Preparation of test sample” and has been revised and now
provides with specification of the preparation of the test pieces for the test without (6.1) and under
confinement (6.2) considering bulk and cartridged explosives;
g) Clause 7 “Procedure” has been revised and enlarged to provide with separate specifications on the
attachment of the means to measure the velocity of detonation (7.1), the attachment of the means of
initiation (7.2) and the measurement (7.3);
h) Figures 2, 3, 5 and 7 have been added to the document, the existing figures have been revised;
i) Clause 8 “Expression of results” has been added;
j) 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;
k) former Annex A “Range of applicability of the test method” has been removed;
l) Annex ZA has been updated;
m) the Bibliography has been added and lists, e.g. 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.

4 Principle
The velocity of detonation is an important performance characteristic of explosives for blasting.
The determination of the velocity of detonation (VOD) is carried out by measuring the time it takes the
detonation front to travel a distance through a test piece. The test is carried out either under confinement
or without. Depending on the measuring equipment, the velocity of detonation is calculated from the
measured time and the measured distance or derived from the distance over time test records.
5 Apparatus
5.1 Means of initiation, as specified for the explosive tested in accordance with EN 13631-1:2025,
4.1.4, being a detonator, a detonating cord with a detonator or a booster with a detonator.
5.2 Steel tube, of steel grade S 235 in accordance with EN 10025-2:2019, Clause 4 and Tables 1, 3 and
6, and with dimensions in accordance with EN 10216-1:2013, Table 7.
In case of bulk explosives, the resulting inner diameter of the steel tube shall be the nearest diameter
equal to or greater than the minimum diameter specified in accordance with EN 13631-1:2025, 4.1.9. The
wall thickness of the steel tube shall be the smallest preferred value as given for the outer diameter in
EN 10216-1:2013, Table 7.
In case of cartridged explosives being tested under confinement, the resulting inner diameter of the steel
tube shall have the smallest diameter where the cartridges with the minimum diameter specified in
accordance with EN 13631-1:2025, 4.1.9, can still be inserted. The wall thickness of the steel tube shall
be the smallest preferred value as given for the outer diameter in EN 10216-1:2013, Table 7.
If the start-stop-method (5.4.1) is used for measuring the velocity of detonation, there shall be two holes
in the tube to allow the insertion of the sensors of the measuring equipment at positions in accordance
with 7.1.1. The diameter of the holes shall be just large enough for the sensors to be inserted.
5.3 Plastic liner, made of a thin plastic film. The plastic liner shall have a cylindrical shape.
