This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 321.
If this draft becomes a European Standard, 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.
This draft European Standard was established by CEN 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 (prEN 13631-11:2021) 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 13631-11:2003.
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) Annex A, Range of applicability of the test method, has been removed;
d) 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

1 Scope
This document specifies a test method for the determination of the ability of cartridged explosives to
transmit detonation.
The method is applicable to explosives in cartridges, excluding black powder, explosives pre-products
and other non-detonating explosives.
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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in prEN 13857-1:2021 and the
following apply.
3.1
cap-sensitive explosive
explosive which can be initiated by a single detonator
4 Principle
The transmission of detonation is determined by testing the ability of two unconfined and coaxially
suspended cartridges to transmit the detonation from one to the other, where the cartridges have the
same diameter and are separated by an air gap.
While normally the cartridges in a borehole shall be in direct contact which each other, forming an
uninterrupted column of explosives, in practice it cannot always be excluded that smaller objects drop
in between and generate a small separation. This test adds to the safety in use.
When the manufacturer claims that the explosive will need confinement in order to properly function,
the transmission of detonation is determined with the explosive inside a steel tube of suitable
dimensions.
The donor cartridge when initiated shall initiate the acceptor cartridge.
The temperature during the test shall be within the range of use given by the manufacturer.

5 Apparatus
5.1 Means of initiation, as specified by the explosives’ manufacturer.
5.2 Support, for holding the cartridges, comprising a thin wooden or metal rod or other device which
will not affect the velocity of detonation. When confinement of the explosive is required, the support
shall hold the cartridges inside a steel tube (5.3).
5.3 Steel tubes, the dimensions 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 10025-1:2005 as “S 235 xx”.
The internal diameter of the steel tube shall be th
