European foreword
This document (prEN 13631-7:2021) 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 for the CEN Enquiry.
This document will supersede EN 13631-7:2003.
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) the normative references have been updated;
c) Clause 4, Principle, has been added;
d) 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 13631, Explosives for civil uses — Explosives, is currently composed with the following parts:
— Part 1: Requirements
— Part 2: Determination of thermal stability of explosives
— Part 3: Determination of sensitiveness to friction of explosives
— Part 4: Determination of sensitiveness to impact of explosives
— Part 5: Determination of resistance of explosives to water
— Part 6: Determination of resistance of explosives to hydrostatic pressure
— Part 7: Determination of safety and reliability of explosives at extreme temperatures
— Part 10: Method for the verification of the means of initiation of explosives
— Part 11: Determination of transmission of detonation of explosives
— Part 13: Determination of density of explosives
— Part 14: Determination of velocity of detonation of explosives
1 Scope
This document specifies a method for determining safety and reliability of explosives for civil uses,
excluding black powder, at extreme temperatures.
NOTE Extreme temperatures are considered to be below −40°C or above + 80 °C.
