European foreword
This document (EN 13631-5:2025) 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withdrawn at the latest by April 2026.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 13631-5:2002.
EN 13631-5:2002:
a) the document title has been changed from “Explosives for civil uses — High explosives — Part 5:
Determination of resistance to water” to “Explosives for civil uses — Explosives for blasting,
boosters and explosive substances — Part 5: Verification of the resistance to water of explosives for
blasting and boosters”;
b) the Scope has been revised and now specifies the covered and not covered explosives;
c) the normative references have been updated;
d) the former Clause 4 “Preliminary test for cartridged explosives” has been revised and moved to the
new normative Annex A;
e) the new Clause 4 “Principle” has been added;
f) the specifications of former Clauses 5 and 6 have been completely revised and restructured and are
now given in the new Clauses 5, 6 and 7;
g) the new Clause 7 “Procedure” provides with a completely revised test method to verify the
resistance to humid or wet conditions;
h) the Clause 8 “Expression of results” has been added;
i) the Clause “Test report” does no longer require conformity with EN ISO/IEC 17025 and the
information to be provided has been revised;
j) the former Annex A “Range of applicability of the test method” has been removed;
k) the Annex ZA has been updated;
l) 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.

1 Scope
This document specifies a test method for the verification of the resistance to water of explosives for
blasting and boosters.
NOTE This test method applies to situations where an explosive for blasting or a booster is subjected to high
humidity and contact with water.
This document does not apply to black powder.
This document does not apply to explosive substances.

4 Principle
Water can adversely affect the safety or reliability of explosives resulting in a failure to initiate or to
detonate completely. For the verification of the resistance to humid or wet conditions, a test piece is
immersed into water. Afterwards, the explosive is initiated, and complete detonation indicates
resistance to water.
In case of cartridged explosives, the test distinguishes between cartridged explosives where the cover
material is necessary to provide water resistance or not. In the first case the cover material is subjected
to a preliminary test to prove the suitability of the cover material to withstand mechanical stress during
loading of the explosive cartridges. In the latter case the cover material is cut prior to testing, in order to
enable contact of the explosive with the water.
5 Apparatus
5.1 Means of initiation, as specified for the explosive in accordance with EN 13631-1:2025, 4.1.4 or
6.1.5, as applicable.
5.2 Water tank, of a size big enough to provide for a complete immersion in water of the test piece in
horizontal position and assembled with means of initiation (5.1). The height of the water tank shall be
sufficient to hold water to a depth of at least 20 cm plus the diameter of the test piece.
Alternatively, a tubular water tank for vertical immersion of the test piece may be used. The tubular
water tank shall have a diameter at least twice the diameter of the test piece (see Clause 6). The height
of the tubular water tank shall be sufficient to hold water of a depth of at least 20 cm plus the length of
the test piece.
5.3 Means to verify complete detonation

accordan
