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.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

prEN 13857-1:2021 (E)
— shell;
b) technical revision of the definitions of the term
— witness plate;
c) deletion of the terms
— range of applicability of a test method; and
— range of validity of a test method.
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 13857, Explosives for civil uses, is currently composed of the following parts:
— Part 1: Terminology
— Part 3: Information to be provided by the manufacturer or his authorised representative to the user
prEN 13857-1:2021 (E)
1 Scope
This document defines the key technical terms used in the European Standards developed in the field of
explosives for civil uses.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
abrasion resistance
ability to withstand the reduction of the thickness of the covering of detonator leading wires or of
detonating cord or of shock tube by local friction
3.2
acceptor charge
charge of explosive receiving a stimulus from another charge
3.3
base charge
explosive mass contained in the base of a detonator and intended to provide the main output energy
Note 1 to entry: A base charge normally consists of a secondary explosive, for example pentaerythritol tetranitrate
(PETN).
3.4
black powder
intimate mixture of sodium nitrate or potassium nitrate with charcoal or other carbon, with or without
sulphur
3.5
blasting accessory
non-explosive device used in blasting
EXAMPLE Blasting machines, circuit testers, shot firing cable.
3.6
booster
explosive device used as a donor charge to amplify the energy supplied to the acceptor charge
3.7
bridgewire
resistance wire connecting the leading wires inside an electric detonator or electro-explosive device
3.8
bulk explosive
explosive which is not cartridged and can be loaded by pouring (under gravity), pumping or pneumatic
means
prEN 13857-1:2021 (E)
3.9
burning duration
time for burning through a defined length of safety fuse
Note 1 to entry: Given in seconds (s).
3.10
cartridged explosive
explosive enclosed in a casing (usually cylindrical) formed from paper, cardboard, plastics or other
material and used in this form
3.11
complete detonation
reaction of an explosive charge, where the entire charge is consumed as a detonation front travels
through it
Note 1 to entry: One means of verifying complete detonation is the measurement of VOD where the measured VOD
lies within a range for acceptance.
3.12
composition
substance or mixture of substances designed to produce an effect by heat, gas or a combination of these,
as a result of self-sustaining exothermic chemical reactions
3.13
coupling accessory
device for transferring a shockwave which does not include an explosive charge
3.14
crimp
compression closure at the end of a detonator to hold in place safety fuse or to secure and provide a seal
for shock tube or leading wires of an electric fuse
3.15
decomposition
chemical reaction of a substance which is not a detonation, resulting in significant change in properties
3.16
deflagration
reaction of combustion through a substance at sub-sonic velocity in the reacting substance
3.17
delay detonator
detonator assembly in which a time delay between activation and detonation is included
Note 1 to entry: Delay detonators can be electronic, electric or non-electric.
3.18
delay element
part of a delay detonator which provides a time delay between activation of the detonator and detonation
of the base charge
prEN 13857-1:2021 (E)
3.19
delay interval
difference in time between adjacent detonators in a delay series
3.20
delay number
number given to a delay detonator to show its relative position in a given series
3.21
delay time
elapsed time between the activation and detonation of a delay detonator
3.22
detonation
reaction which moves through an explosive material at supersonic velocity in the reacting material
3.23
detonating cord
article consisting of a core of detonating explosive (usually PETN) surrounded by a flexible outer covering
or clad by soft metal tube
Note 1 to entry: The explosive charge in a detonating cord can vary from 1,0 g/m to 200 g/m.
3.24
detonating cord relay
article containing tubes with charges of pyrotechnic delay composition and explosive, used to connect
detonating cords and provide a defined delay in the propagation of detonating cord
3.25
detonator
article consisting of a small metal or plastics tube containing a primary explosives charge such as lead
azide, and a secondary explosives charge such as PETN, or other combinations of explosives normally not
exceeding a mass of 2 g
3.26
donor
exploding charge producing an impulse that impinges upon an explosive “receptor” charge
3.27
donor charge
charge of explosive supplying a stimulus to another charge
3.28
electric detonator
detonator assembly activated by means of an electrical current
Note 1 to entry: Electric detonators include DC and AC (magnetical
