4 Categories and types of ignition devices
4.1 Generic types
The generic types are defined as follows:
4.1.1 Igniter: Article containing pyrotechnic composition(s) used to initiate combustion or
deflagration. They may be actuated by chemical, electrical, optical or mechanical means.
NOTE Complex igniters (e.g. some integral rocket igniters) are not considered as subtypes of “igniters”, but
linked to “gas generators” or “heaters” (see prEN 16263-1, prEN 16263−2, prEN 16263−3, prEN 16263−4 and
prEN 16263−5).
4.1.2 Component for pyrotechnic trains: Article, excluding the other generic types containing
pyrotechnic composition(s) designed to transmit a pyrotechnic reaction or effect within a pyrotechnic
train. They can include bursting charges and lift charges.
4.1.3 Pyrotechnic cord and fuse: Article consisting of black powder or other pyrotechnic
composition(s) either coated on a supporting medium and/or inside a tube with or without a protective
covering.
4.1.4 Delay fuse: Article consisting of a casing with a core of compacted pyrotechnic composition.
Designed to transmit ignition over a time period.
4.1.5 Fuse: Device which incorporates mechanical, electrical, chemical or hydrostatic components
and one or more pyrotechnic composition(s) to initiate a pyrotechnic train.
4.1.6 Hand-held igniter: Article with pyrotechnic composition(s) used to initiate combustion and
designed to be held in the hand.
4.1.7 Pyrotechnic train: Combination of articles of other generic types which are functionally linked
and, after an initial input of energy, function in a designed sequence to transmit, enhance, distribute
and/or delay ignition to one or more other pyrotechnic components.
4.2 Subtypes
The generic types can include the following subtypes:
4.2.1 Black match: Pyrotechnic cord and fuse consisting of textile yarns covered with black powder or
another fast burning pyrotechnic composition. It burns progressively along its length with an external
flame and is used to transmit ignition.
4.2.2 Cord igniter: Pyrotechnic cord and fuse consisting of a core of pyrotechnic composition
surrounded by a flexible woven fabric, plastic or similar close fitting sheath. It burns progressively
along its length with an external flame and is used to transmit ignition.
4.2.3 Delay element: Delay fuse consisting of a core of fine grained black powder surrounded by a
flexible woven fabric with or without one or more protective outer coverings.
NOTE Frequently, when used as a component of fireworks, it is axially inserted into a solid rigid part.
4.2.4 Delay igniter: Igniter with a delay unit designed to transmit ignition over a time period.
The delay unit may be either pyrotechnic – a delay fuse – or non-pyrotechnic (e.g. electronic).
4.2.5 Electric igniter: Electrically actuated igniter. Electric current is used to heat a resistive element
(e.g. bridge wire). The sensitive pyrotechnic composition in contact with the resistive element is ignited
by heat transfer. The article initiates a pyrotechnic train or component by the deflagration that is
generated.
4.2.6 Ignition cartridge: See “squib”.
4.2.7 Ignition tube: Pyrotechnic cord and fuse as defined in 3.2.27.
4.2.8 Mechanical igniter: Mechanically actuated igniter. A mechanical signal (e.g. percussion,
friction) is used to ignite a pyrotechnic composition sensitive to the mechanical signal. The article
initiates a pyrotechnic train or component by the deflagration of the pyrotechnic composition.
4.2.9 Optical igniter: Optically actuated igniter. Optical condensed light, transmitted through an
optical fibre, is used to ignite a pyrotechnic composition by radiative heat transfer. The article initiates a
pyrotechnic train or component by the deflagration of the pyrotechnic composition.
4.2.10 Pressed fuse: Delay fuse where pyrotechnic composition is pressed in a rigid case. Pyrotechnic
composition burns progressively along the device length with an internal flame.
4.2.11 Primer: Igniter consisting of a cap containing pyrotechnic composition(s) for ignition, with or
without an auxiliary charge, designed to ignite the propelling charge in a cartridge case.
4.2.12 Quick match: Pyrotechnic cord and fuse consisting of textile yarns covered with black powder
or another fast burning pyrotechnic composition wrapped loosely in a paper or plasticised paper pipe
or sheath. It burns progressively along its length with an external flame and a linear burning rate of
several metres per second.
4.2.13 Squib: Igniter with a boosting charge, designed to amplify the pyrotechnic output of the igniter.
4.2.14 Reactive tape: Pyrotechnic cord or fuse consisting of an adhesive tape with a line of black
