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.

This document will supersede EN 13763-18:2003.
In comparison with the previous edition, the following technical modifications have been made:
a) Clause 1, Scope, now specifies that this document is applicable to explosives for civil uses;
b) Clause 4, Principle, has been added;
c) in Clause 6, Preparation and handling of test samples and test pieces, 6.1, Handling of test samples, has
been added;
d) in Clause 7, Procedure, 7.1, Conditioning and test temperature, has been added.
e) Clause 8, Expression of results, has been added.
f) Annex A, Range of applicability of the test method, has been removed;
g) 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.

Introduction
During blasting using electric detonators, the detonators are usually connected in series. To avoid misfire,
the electrical characteristics of the detonators need to be within narrow tolerances.
