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) Clause 1, Scope, has been revised and black powder has been included;
c) the normative references have been updated;
d) in Clause 3, Terms and definitions, the terms 3.1, 3.2 and 3.4 have been added;
e) Clause4, Principle, has been added;
f) Clause 7, Procedure, has been revised for clarification purposes;
g) Figures 1 and 2 have been removed;
h) 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.
