European foreword
This document (prEN 16261-1:2021) has been prepared by Technical Committee CEN/TC 212
“Pyrotechnic articles”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16261-1:2012.
In comparison with the previous edition, the following technical modifications have been made:
— new terms: “detonation” and “detonative explosive” were added;
— new component was added: “comet”.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of Directive 2013/29/EU on the
harmonisation of the laws of the Member States relating to the making available on the market of
pyrotechnic articles.
For relationship with Directive 2013/29/EU, see informative Annex ZA, which is an integral part of this

3.1.3
subtype
set of articles within a generic type with specific design features
3.1.4
individual item
article within a generic type and/or a subtype, for which every possible feature and characteristic has
been fixed
Note 1 to entry: Each feature and characteristic will be specified in the technical name or a technical data sheet,
as appropriate.
3.1.5
technical name
general description of an individual item
3.1.6
trade name
description of an individual item from a particular supplier
3.1.7
compound firework
device in which all the individual elements have been EC-type certified and which does not need any
new specific EC-type certification

3.2 Technical terms
3.2.1
Acceptance Quality Level
AQL
quality level that is the worst tolerable process average when a continuing series of lots is submitted for
acceptance sampling
3.2.2
batch test
test performed on a sample of products taken at random from a production batch to check compliance
with a given standard
Note 1 to entry: Batch testing needs all products in the production batch comply with the characteristics the
standard requires to ensure homogeneity of the whole batch. It aims at proving that all products which are placed
on the market are in conformity with the type which is described in the EC type-examination certificate and have
been successfully submitted to type tests as determined by the standard.
3.2.3
burst height
altitude of the bursting point of the effect or the article
Note 1 to entry: For single break shells, this is the height at which the bursting charge of the shell functions. For
complex shells, it is the highest bursting effect.
3.2.4
calibre
external diameter of a firework designed to be fired from a mortar tube (e.g. shell) or the internal
diameter of a tube which contains pre-assembled items (e.g. a roman candle)
Note 1 to entry: It is important that the internal diameter of the mortar tube is close to the external diameter of
the firework, enabling the existence of a peripheral gap which is a compromise between the necessity of a free
motion of the firework in the tube and a lowest escape of lift gases passing by the firework during its motion in the
tube.
3.2.5
critical nonconforming unit
nonconforming unit with one or more critical nonconformities, with or without major or minor
nonconformities
3.2.6
critical nonconformity
nonconformity that judgement and experience indicate is likely to result in hazardous or unsafe
conditions
Note 1 to entry: This type of nonconformity is referred to as 'class A nonconformity' in ISO 2859-1.
3.2.7
debris
any part of the firework which remains after the firework has ceased to function
Note 1 to entry: Chemical products resulting from the combustion of the pyrotechnic compositions are not
considered as “debris”.

3.2.8
delay fuse
fuse incorporated into the initial fuse of a firework to introduce a delay between firing and functioning
or the internal fuse in a firework to enable sequential firing of elements of the firework (e.g. in a shell)
3.2.9
detonation
reaction which propagates through an explosive at supersonic velocity in the reacting explosive
3.2.10
detonative explosive
substance or mixture of substances which can undergo a fast internal decomposition reaction leading to
a detonation in normal use
3.2.11
drift
movement of a firework away from the direction of firing, as a result of the action of the wind or other
effects
Note 1 to entry: For instance, an aerial wheel might drift away from the vertical direction in which it was fired.
Drift can be quantified in terms of angle or distance.
3.2.12
effect broadness
broadness of effect
horizontal dimension of the firework effect
3.2.13
effect height
maximum height achieved by the firework
Note 1 to entry: For a shell, this would equate to the burst height plus the burst radius of the shell. For
waterfalls, this corresponds with the vertical length of the effect.
3.2.14
effect range
horizontal distance between the firing point and the point of explosion (or functioning) on to the water
3.2.15
effect time
total duration of effect from its visible and/or aural emergence until vanishing
3.2.16
end closure
part or crimp which is designed to seal one end of a firework case
3.2.17
explosion
sudden release of energy accompanied by a bang with or without a flash

3.2.18
firework case
container which is designed to retain pyrotechnic compositions
Note 1 to entry: According to its mechanical strength, this container may intentionally (by design) influence the
firework's behaviour.
3.2.19
firing angle
angle (measured from the vertical) of an item as prepared for firing
3.2.20
flash powder
uncompacted pyrotechnic composition used to produce an aural effect, with or without emission of an
intense and short flash light, or used as a bursting charge or lifting charge
3.2.21
friction head
ignition head designed to be ignited by friction
Note 1 to entry: See “ignition head”.
3.2.22
fuse
small tube or cord containing a pressed or compacted pyrotechnic composition which burns gradually
to ignite a pyrotechnic composition or article
Note 1 to entry: By extension, this term also applies to other types of fire transmission devices like quickmatch
or blackmatch or pressed fuse.
Note 2 to entry: See also “delay fuse”.
3.2.23
gross mass
total mass of the firework (not including any ancillary equipment (e.g. frames))
3.2.24
ignition head
initial fuse consisting of pyrotechnic composition only
3.2.25
initial fuse
component of a firework which is ignited in order to start the firework functioning
3.2.26
initial fuse time
burning time of the initial fuse

nonconforming unit with one or more major nonconformities, with or without minor nonconformities,
but with no critical nonconformities
3.2.29
major nonconformity
nonconformity, other than a critical nonconformity, which is likely to result in failure, to reduce
materially the usability of the firework, or to increase the potential hazard
Note 1 to entry: This type of nonconformity is referred to as ‘class B nonconformity’ in ISO 2859-1.
3.2.30
minor nonconforming unit
nonconforming unit with one or more minor nonconformities, but with no critical or major
nonconformities
3.2.31
