c) Clause 5, Apparatus, has been updated;
d) Clause 6, Preparation and handling of test samples and test pieces, has been updated;
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.
