European foreword
This document (prEN 13630-5:2021) 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 13630-5:2003.
In comparison with the previous edition, the following technical modifications have been made:
a) the normative references have been updated;
b) in Clause 3, Terms and definitions, the terms 3.1 and 3.2 have been added;
c) Clause 4, Principle, has been added;
d) Annex A, Range of applicability of the test method, has been removed and the content has been revised
and moved to Clause 1, Scope;
e) Annex C, Availability of abrasive strips, has been removed and the content has been revised and
moved to a footnote to 5.2.2, Abrasive strips;
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 13630, Explosives for civil uses — Detonating cords and safety fuses, is currently composed of the

1 Scope
This document specifies a method to determine the resistance to abrasion of detonating cords.
Applicability of the test method is ambient laboratory conditions.
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
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
abrasive strip
strip of steel with a specific grinding pattern on its surface
3.2
explosive core
explosive material in the centre (axis) of the cord
4 Principle
The resistance to abrasion of detonating cord is assessed by subjecting test samples to the wear of an
abrasive strip.
5 Apparatus
5.1 Digital timer with relay output, capable of:
— being set to a predetermined time in the range of (0 to 10) s ± 0,01 s;
— being started (triggered) when the hinged arm is lifted by the test piece;
— automatically stopping the rotor when the predetermined time has elapsed.
5.2 Abrasion test apparatus, as shown in Figure 1, comprising the following main components.
