This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13763-7:2003.
In comparison with the previous edition, the following technical modifications have been made:
a) Clause 1, Scope, has been revised:
1) it is now specified which detonators are covered by the document and electronic detonators have
been added;
2) it has been added that the document applies to explosives for civil uses;
b) Clause 4, Principle, has been added;
c) Clause 8, Expression of results, has been added;
d) Annex A, Range of applicability of the test method, has been removed;
e) Annex ZA has been added.
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 normal use on site, the crimps/closures of detonators and their leading wires or shock tubes can
be subjected to pulling forces. Such forces can cause a pull-out of internal components of the detonator.
For example:
— the shock tube can be pulled out of the detonator through the sealing plug;
— the leading wire, fuse head and sealing plug
