3.1.1

category 4

fireworks which present a high hazard, whose handling and use require specialist knowledge and whose noise level is not harmful to human health

3.1.2

type

sample representative of the production envisaged used in type tests (3.2.47)

3.1.3

generic type

set of articles with a common, very general, design feature and/or with a common characteristic effect

3.1.4

subtype

set of articles within a generic type (3.1.3) with specific design features

3.1.5

individual item

article within a generic type (3.1.3) and/or a subtype (3.1.4) , 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 (3.1.6) or a technical data sheet, as appropriate.

3.1.6

technical name

general description of an individual item (3.1.5)

3.1.7

trade name

description of an individual item (3.1.5) from a particular supplier

3.1.8

compound firework

device in which all the individual elements have been type certified and which does not need any new specific type certification

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 to comply with the characteristics the standard requires to assure 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 type-examination certificate and have been successfully submitted to type tests (3.2.47) 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 (3.2.31) 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 (3.2.33) with one or more critical nonconformities (3.2.6) , with or without major or minor nonconformities

3.2.6

critical nonconformity

nonconformity (3.2.34) that judgment and experience indicate is likely to result in hazardous or unsafe conditions

Note 1 to entry: Chemical products resulting from the combustion of the pyrotechnic compositions (3.2.42) are not considered as"debris".

3.2.8

delay fuse

3.2.9

drift

movement of a firework away from the direction of firing, as a result of the action of the wind or other effects

3.2.10

effect broadness

broadness of effect

horizontal dimension of the firework effect

3.2.11

effect height

maximum height achieved by the firework

Note 1 to entry: For a shell, this would equate to the burst height (3.2.3) plus the burst radius of the shell. For waterfalls, this corresponds with the vertical length of the effect.

3.2.12

effect range

horizontal distance between the firing point and the point of explosion (3.2.15) (or functioning) on to the water

3.2.13

effect time

total duration of effect from its visible and/or aural emergence until vanishing

3.2.15

explosion

sudden release of energy accompanied by a bang with or without a flash

3.2.16

firework case

container which is designed to retain pyrotechnic compositions (3.2.42)

Note 1 to entry: According to its mechanical strength, this container may intentionally (by design) influence the firework's behaviour.

3.2.17

firing angle

angle (measured from the vertical) of an item as prepared for firing

3.2.18

flash composition

uncompacted pyrotechnic composition (3.2.42) used to produce an aural effect, with or without emission of an intense and short flash light, or used as a bursting charge

3.2.19

friction head

ignition head (3.2.23) designed to be ignited by friction

3.2.20

fuse

small tube or cord containing a pressed or compacted pyrotechnic composition (3.2.42) 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 (3.2.8) ".

3.2.21

gross mass

total mass of the firework

Note 1 to entry: This does not include any ancillary equipment (e.g. frames).

3.2.22

group

set of individual items (3.1.5) which will be considered together for the purposes of testing and certification

Note 1 to entry: Synonymous with"family".

3.2.23

ignition head

nonconformity (3.2.34) , other than a critical nonconformity (3.2.6) , 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 a ‘class B nonconformity’ in ISO 2859-1:1999.

3.2.29

minor nonconforming unit

nonconforming unit (3.2.33) with one or more minor nonconformities (3.2.30) , but with no critical or major nonconformities

3.2.30
