European foreword
This document (prEN 13631-14:2021) has been prepared by Technical Committee CEN/TC 321
“Explosives for civil uses”, the secretariat of which is held by UNE.
This document is currently submitted for the CEN Enquiry.
This document will supersede EN 13631-14:2003.
In comparison with the previous edition, the following technical modifications have been made:
a) the main element of the document’s title has been changed from “High explosives” to “Explosives”;
b) the normative references have been updated;
c) a new method for measuring the velocity of detonation by means of a continuous wire probe has
been added;
d) the description of the preparatory steps and for performing the test have been clearly separated;
e) Annex A, Range of applicability of the test method, has been removed and the content has been
moved to Clause 1, Scope;
f) Annex ZA has been updated.
This document has been prepared under a Standardization Request (M/562) annexed to the
Commission Implementing Decision C(2019)6634 final as regards Explosives for civil uses given to CEN
by the European Commission and the European Free Trade Association, and supports Essential Safety
requirements of Directive 2014/28/EU.
For relationship with Directive 2014/28/EU, see informative Annex ZA, which is an integral part of this
document.
EN 13631, Explosives for civil uses — Explosives, is currently composed with the following parts:
— Part 1: Requirements
— Part 2: Determination of thermal stability of explosives
— Part 3: Determination of sensitiveness to friction of explosives
— Part 4: Determination of sensitiveness to impact of explosives
— Part 5: Determination of resistance of explosives to water
— Part 6: Determination of resistance of explosives to hydrostatic pressure
— Part 7: Determination of safety and reliability of explosives at extreme temperatures
— Part 10: Method for the verification of the means of initiation of explosives
— Part 11: Determination of transmission of detonation of explosives

1 Scope
This document specifies a test method for determining the velocity of detonation of boosters and
explosives, excluding black powder, explosive pre-products and other non-detonating explosives.
Applicability of the test method is under environmental conditions of a field test range or blast bunker.
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.

alloy structural steels
3 Terms and definitions
For the purposes of this document, the terms and definitions given in prEN 13857-1:2021 apply.
4 Principle
The time is measured it takes for the detonation front to travel a distance. The velocity of detonation
(see prEN 13857-1:2021, abbreviated VOD) is the quotient of this distance over the measured time. The
velocity of the detonation front has to stabilize under the given conditions (diameter of explosive
charge, with or without confinement) which is why a propagation length (see prEN 13857-1:2021,
abbreviated VOD) has to be given, before a meaningful value of the VOD can be determined.
The VOD is influenced by the density of the explosive, however only to a small extent. Therefore, the
VOD depends little on temperature, as long as the explosive does not undergo a physical or chemical
change due to low or high temperatures.
NOTE The VOD is one of the performance characteristics of an explosive.
5 Apparatus
5.1 Means of initiation
As specified by the explosives’ manufacturer.
5.2 Steel tubes
The dimensions of the steel tubes shall be in accordance with Table 1.
The steel quality shall be structural steel with a minimum yield strength of 235 MPa at 16 mm, which is
specified in accordance with EN 10025-2:2005 as “S 235 xx”.
In case of cartridged explosives, the internal diameter of the steel tube shall be the smallest where the
cartridges still can be inserted into it without difficulty.
In case of bulk explosives, the internal diameter of the steel tube shall be the nearest diameter equal or
less to the smallest diameter which the manufacturer specifies for use of the bulk explosive.

In case the start-stop-method (5.4.2) is used, holes shall be drilled in the tube to allow the insertion of
the sensors of the measuring equipment at positions in accordance with 6.2. The diameter of the holes
shall be no larger than to allow the insertion of the sensors (5.4.2).
