European foreword
This document (prEN 13631-3:2021) 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 13631-3:2005.
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) 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
— Part 11: Determination of transmission of detonation of explosives
— Part 13: Determination of density of explosives

1 Scope
This document specifies a test method for determining the sensitiveness to friction of explosives.
This method is not applicable to liquid 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.
prEN 13857-1:2021, Explosives for civil uses — Part 1: Terminology
EN 60672-3:1997, Ceramic and glass-insulating materials - Part 3: Specifications for individual materials
3 Terms and definitions
For the purposes of this document, the terms and definitions given in prEN 13857-1:2021 apply.
4 Principle
A small amount of the explosive is placed on a porcelain plate and a porcelain peg is pressed onto the
sample under a specified load. The plate is moved to apply a friction stimulus to the sample. The load is
reduced for subsequent trials until the lowest load at which a reaction is obtained from at least one out
of six trials is reached. This load level is the level of sensitiveness to friction.
Knowledge of the sensitiveness to friction of explosives is of paramount importance to control risks
during handling and to prevent inadvertent ignition.
5 Preparation of test samples
5.1 Solid substances which are easily broken up or in powdered form
Granular substances shall be passed through a sieve with a nominal aperture size of 0,5 mm.
Substances which have been compressed, cast or otherwise consolidated shall be broken into small
pieces before sieving. The fraction which passes through the sieve shall be used for the test.
For substances which contain more than one consti
