article considered an explosive (3.1.1)
Note 1 to entry: An explosive article contains one or more explosive materials (3.1.2).
3.1.4
explosion
rapid increase in volume and release of energy with generation of high temperatures and release of gases
that causes pressure waves in the material in which it occurs
Note 1 to entry: An explosion is categorized as deflagration (3.1.5) if the pressure waves are subsonic and as
detonation (3.1.6) if they are supersonic (shock waves).
3.1.5
deflagration
explosion (3.1.4) with pressure waves at subsonic velocity

detonation
explosion (3.1.4) with pressure waves at supersonic velocity
3.1.7
complete detonation
detonation (3.1.6) where the explosive material (3.1.2) or the explosive article (3.1.3) has completely
reacted
Note 1 to entry: A complete detonation can be verified by the measurement of the velocity of detonation (3.1.9).
3.1.8
sympathetic detonation
initiation (3.1.20) of an explosive (3.1.1) by the detonation (3.1.6) of another explosive in the vicinity
Note 1 to entry: The impulse from another detonation (3.1.6) can be transmitted through air, earth or water.

VOD
detonation velocity
velocity at which the detonation (3.1.6) moves through the explosive material (3.1.2)
3.1.10
detonation front
moving zone in the reacting explosive (3.1.1) composed of the shock that drives the detonation (3.1.6) and
the reaction zone in which the chemical reaction takes place
3.1.11
blasting explosive
explosive for blasting
explosive (3.1.1) used for breaking rock or other materials that it is in contact with
3.1.12
explosive substance

3.1.15
bulk explosive
solid, liquid or pasty explosive material (3.1.2) in loose form which is not enclosed in a cartridge (3.1.14)

detonating cord (3.4.1)
3.1.20
initiation
process of starting the chemical reaction of an explosive (3.1.1) that leads to an explosion (3.1.4)
Note 1 to entry: In practise, the terms initiation and ignition (3.1.22) are sometimes used interchangeably.
3.1.21
means of initiation
means to start the chemical reaction of an explosive (3.1.1) that leads to an explosion (3.1.4)

process of starting the chemical reaction of an explosive (3.1.1) that leads to a combustion or a
deflagration (3.1.5)
Note 1 to entry: In practise, the terms initiation (3.1.20) and ignition are sometimes used interchangeably. For
reasons of distinction, in CEN/TC 321 documents, the term ignition, means of ignition (3.1.23) and the verb “ignite”
are used in connection with explosives (3.1.1) that, if functioning as designed, will undergo deflagration (3.1.5) or
combustion but no detonation (3.1.6).

means to start the chemical reaction of an explosive (3.1.1) that leads to a deflagration (3.1.5) or
combustion
