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.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.

European foreword
This document (prEN 13631-1:2021) 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 to the CEN Enquiry.
This document will supersede EN 13631-1:2005.
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) black powder has been included in Clause 1, Scope;
c) Clause 1, Scope, now states that the Essential Safety Requirements II.1.(h) and II.3.1.(c) are not
addressed in this document;
d) the normative references have been updated;
e) the specifications from 4.7, Safety at loading, have been moved to 4.2, Sensitiveness to friction, and
4.3, Sensitiveness to impact;
f) 4.12, Thermodynamic properties, has been removed;
g) 4.11, Chemical purity, 4.12, Environmentally friendly disposal, 4.13, Suitable instructions, 4.14, 'use by'
date, and 4.15, Burning rate of black powder, have been added;
h) Clause 5, Other tests, including 5.1, Toxic gases, and 5.2, Explosives for use in hazardous environments,
have been removed.
i) 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 to water
— Part 6: Determination of resistance to hydrostatic pressure

— Part 7: Determination of safety and reliability at extreme temperatures
— Part 10: Method for the verification of the means of initiation

— Part 13: Determination of density
— Part 14: Determination of velocity of detonation of explosives

1 Scope
This document specifies the requirements for explosives for civil uses, including black powder.
The Essential Safety Requirements (ESR) II.1.(h) and II.3.1.(c) of the Directive 2014/28/EU, Annex II are
not addressed in this document.
NOTE 1 ESR II.1.(h) addresses the “suitability of the explosive for use in hazardous environments”. The
conditions and the type of hazards of “hazardous environments” depend on the field in which an explosive is to be
used and are different in different countries. Since there is no universal approach to address safety under such a
broad range of conditions, it is not possible to address this ESR by a verification done only with the explosive. It is
common practice that national or even local provisions address very specifically the hazards found in a specific
mining environment.
NOTE 2 ESR II.3.1.(c) addresses the toxicity of “fumes produced by blasting explosives intended for underground
use”. The health of workers can only be protected by providing strong ventilation and avoiding any contact of people
with fumes produced by explosives. The conditions and efficiency of ventilation, and the applicable threshold levels
are unknown during the phase of testing or design of an explosive and therefore cannot be addressed by a
verification applied to the explosive alone.
