Introduction

Directive 2007/23/EC of May 23 2007 on the placing on the market of pyrotechnic articles, has been

published on June 14 2007 in the Official Journal of the European Union. (Ref. Mandate M 416).

In its Annex 1, Directive 2007/23/EC gives the essential safety requirements (ESR) pyrotechnic articles shall

comply with. In order to facilitate the process of demonstrating compliance with these ESR, harmonized

standards for the design, manufacture and testing of pyrotechnic articles must be developed.

CEN has been mandated by the European Commission (EC) to develop these harmonized standards:

Mandate M 416 describes the work that CEN shall perform.

CEN has entrusted coordination of this work to CEN/TC 212 ‘Pyrotechnic articles’ with the following scope:

“Standardization of fireworks, theatrical pyrotechnic articles, pyrotechnic articles for vehicles and other

pyrotechnic articles, particularly from the point of view of their safe use”.
th th

During its meeting in Delft on October 16 and 17 2007, CEN/TC 212 has decided to share the

corresponding work to be done between several Working Groups. Resolutions have been voted to establish

five Working Groups, one of which is Working Group 2 (CEN/TC 212 / WG2) in charge of standardization of

Category 4 Fireworks.

Because no European standards exist at present for Category 4 Fireworks, preliminary work needs to be

performed before a list of standards to be developed by WG2 can be drawn up. It has been accepted by

CEN/TC 212 and proposed to the European Community a one-year period will be allocated to WG2 to prepare

a CEN Technical Report in which its future work program will be described and an overview of the harmonized

standards it will develop will be given including the reasons why WG 2 propose to develop these standards.

Five work sessions have taken place, respectively in NEN – Delft – Netherlands on February 6 2008, in BAM

st th

– Berlin – Germany on May 21 2008, in NEN – Delft – Netherlands on September 10 2008, in AFNOR –

th rd

Paris – France on November 12 2008 and in UNI – Milano – Italy on February 3 2009.

The present document is the final draft of the Technical Report for Category 4 Fireworks. It has been written in

close coordination with the other working groups of CEN/TC 212 WG 1 “Fireworks, Categories 1, 2 and 3",

WG 3 “Theatrical Pyrotechnic Articles”, WG 4 “Pyrotechnic articles for vehicles” and WG 5 “Other pyrotechnic

articles”.

1 Scope

This Technical Report gives an overview of harmonized standards which will be proposed to be developed by

CEN/TC 212 WG 2, Category 4 Fireworks. It also gives the interpretation WG 2 experts have made of some

terms, definitions and requirements of Directive 2007/23/EC in order to assure future harmonized standards

will encompass all varieties of fireworks, which are presently placed on the European market, in a consistent

way and take the benefit of all the practical experience and usages of fireworks in the Member States.

2 Terminology
2.1 Definition of “C4 Fireworks”

Article 3 (a) of Directive 2007/23/EC gives the following definition of “C4 Fireworks”:

“Fireworks which present a high hazard, which are intended for use only by persons with specialist knowledge

(commonly known as fireworks for professional use) and whose noise level is not harmful to human health”

This definition raises the following comments:

 Exceptions can be found to this definition, because some “fireworks for professional use” – e.g. lances –

cannot be considered as “presenting a high hazard” or generate a low noise level by themselves (e.g.

less than C1 maximum noise level). But they have been designed for use in combination with other

fireworks articles, mainly Category 4 Fireworks. Then they are only used by persons with specialist

knowledge and never offered to the consumer market. Consequently WG 2 experts consider these

articles belong to category 4.

 C1-C2-C3 fireworks articles will no longer be considered as belonging to categories 1, 2 or 3, if they do

not comply with all the requirements of these categories. As soon as a potentially C1, C2 or C3 article

definitively does not meet one of the requirements for C1-C2-C3 Fireworks, it will be categorized as a C4

article.

 Nothing in the definition of “pyrotechnic articles” in Directive 2007/23/EC means an article must be a

complete product. Then the case of “incomplete” fireworks articles must also be considered. Such articles

are commonly placed on the market. An example is a “roman candle without fuse”. This article needs

adaptation of a fuse for its ignition and different types of fuse may be used. This operation can be made

by firers at the firing place, but limited to persons with specialized knowledge.

Another example is a “shell without lift charge”. This article can be used in two distinct ways. It can be

placed in the mortar above a separate “bag charge” which will act as a lift charge and will have been

placed first in the mortar – or – this “bag charge” can be fit to it first before placing the assembly in the

mortar.

Such products require “modification or preparation before use”, which appears to be a better wording than

“incomplete”.

 Likewise, “components” of fireworks can be considered as “pyrotechnic articles” from the point of view of

Directive 2007/23/EC, as far as they are placed on the market. Such pyrotechnic objects as rocket

motors, drivers, delay fuses, shells to be included in more elaborated shells, etc. are used for the

construction of fireworks. Some of them can have other applications than fireworks manufacturing and

are “other pyrotechnic articles” as defined by Directive 2007/23/EC (See Clause 3 hereafter). The others

– which are only used as components of fireworks – can be identified to “fireworks which are intended to

be part of a more elaborate firework”, then as “C4 Fireworks” to be used by persons with specialist

knowledge in pyrotechnical factories.
NOTE The specific case of “stars” is discussed in 4.1.
---------------------- Page: 7 ----------------------
SIST-TP CEN/TR 15951:2009
CEN/TR 15951:2009 (E)

 In the English language, “professional use” mainly means “paid at work” and the sentence between

brackets must be considered as informative but not prevailing. The important term is “person with

specialist knowledge”, which implies these persons are not necessarily paid to prepare and fire the

fireworks.

To conclude and to assure their work will be fully exhaustive, WG 2 experts have adopted the following

interpretation of the definition of C4 Fireworks of Directive 2007/23/EC:

“With respect to Article 3 (a) of Directive 2007/23/EC, Category 4 includes (1) fireworks which present a high

hazard or (2) require modification / preparation before use or (3) are intended to be part of a more elaborate

firework or (4) which do not meet all the requirements for C1-C2-C3 Fireworks, and which are intended for use

only by persons with specialist knowledge (commonly known as fireworks for professional use) and whose

noise level is not harmful to human health.”
Resolution TC 212 28/2008 has been approved by CEN/TC 212.
2.2 Other terms

The future C4 fireworks harmonized standard(s) will identify the design parameters and performance

characteristics to be taken in consideration for the corresponding articles to meet the essential safety

requirements of Directive 2007/23/EC. For each design parameter or performance characteristic it (they) will

state requirements and criteria which shall be complied with.

According to the variety of articles usually observed during C4 fireworks shows, it is clearly noticeable these

articles will not have all in common the same design parameters and performance characteristics. However,

collections of articles sharing the same design parameters and performance characteristics exist. Then WG 2

experts have considered it was necessary to identify these collections of C4 fireworks articles and draw up

their list.

The future harmonized standard(s) will state requirements and criteria for each identified homogeneous

collection, which does not mean there may not exist requirements or criteria applicable to several collections

as well as to all the C4 fireworks articles whatever their design or behaviour in normal use.

Word “type” has been proposed to name these collections of articles. But, this word is already used by

Directive 2007/23/EC, in its Annex II, with another meaning. Then, because Directive 2007/23/EC cannot be

modified, its definition of word “type” must be considered as imperative.

This does not exclude the possibility of using the word “type” in another meaning but – in that case – it has

been suggested to add a qualifying term to it, as it is for the expressions “type of use” and “type of pyrotechnic

article” in Directive 2007/23/EC itself. This proposal has been approved by CEN/TC 212 (See Resolution

43/2008).

Therefore, the following terms and definitions will be used hereafter and in the harmonized standard(s) to be

developed by Working Group 2:
 Type: sample representative of the production envisaged.

NOTE 1 This definition corresponds to the use of the term ‘type’ in Annex II §2(c) of Directive 2007/23/EC for the

purposes of type-examination.

 Generic type: set of articles with a common, very general, design feature and/or with a common

characteristic effect.
 Subtype: set of articles within a generic type with specific design features.

 Individual item: article within a generic type or subtype for which every possible feature and

characteristic has been fixed.
---------------------- Page: 8 ----------------------
SIST-TP CEN/TR 15951:2009
CEN/TR 15951:2009 (E)

NOTE 2 Each feature and characteristic will be specified in the technical name or a technical data sheet, as

appropriate.
 Technical name: general description of an individual item.
 Trade name: description of an individual item from a particular supplier.

 Family: set of individual items that will be considered together for the purposes of testing and approval.

NOTE 3 This last definition is fully compliant with Directive 2007/23/EC which states in “Whereas (18)”: “Groups of

pyrotechnic articles that are similar in design, function or behaviour should be assessed by the notified bodies as product

families”.

The figure hereafter shows how WG 2 experts intend to organize Category 4 Firework articles in “individual

items” (samples of which will be “types”), “families” and “generic types”, starting from the precise design level

to the general design level. Example is given for “shells”.

At the bottom are located the individual items submitted to conformity assessment procedures by the means

of “types”. As shown they are attributed a relatively long name to give information to the users on the typical

calibre and effects (e.g. green ring) of the shell.

In the middle are set up “families” of individual items which may be considered together for the purposes of

testing and certification (samples of which will be groups of the corresponding “types”).

These families exhibit a first level of generalization of the characteristics of individual items and the

corresponding types. For example, their colour and their possible tracing effect are not concerned by the

essential safety requirements of Directive 2007/23/EC. So they can be neglected as far as compliance with

these requirements is concerned and type tests may only be performed on one type and extended by

similarity to others which share the same generalized characteristics.

At the top, a higher level of generalization of the characteristics of types is again possible. For instance, WG2

experts think all types of shells can be put together in a unique collection of groups because they have already

noted that the essential safety requirements of Directive 2007/23/EC will only imply design and performance

requirements which will be common to every type of shells and none at a lower level (e.g. that of a family).

WG2 harmonized standard will only deal with these “generic types”.

2.3 Technical terms

A list of technical terms which will possibly be used in setting design or performance requirements in the future

harmonized standard(s) for C4 Fireworks has also been drawn up. Some of these terms which are presently

used in standards developed by WG1 have strictly the same definition.
This list is given in Annex E.

It will be updated as far as it is necessary during the development phase of WG 2 harmonized standard(s).

3 Interfaces between CEN/TC 212 Working Groups
3.1 Interface between WG2 and WG1

Because drafts of WG 1 harmonized standards for “fireworks, categories 1, 2 and 3” already exist, they have

been taken in account by WG 2 as far as it is necessary to prevent from conflicting situations (See Clause 4

hereafter) or useful when parts of these standards can be profitably applied to C4 fireworks (e.g. some test

methods).

Indeed, WG 1 harmonized standards are not considered as prototypes of WG 2 harmonised standard(s). They

will be distinct documents and requirements of WG 2 harmonised standard(s) will be limited to what is strictly

necessary and sufficient from the point of view of their use by persons with specialist knowledge.

3.2. Interface between WG2 and WG3

WG 2 and WG 3 have exchanged their mutual opinions or solutions whenever they share the same questions

or the same problems (e.g. use of high explosives or nitrocellulose with high nitrogen content in C4, T1 or T2

articles – See 5.1 hereafter)
3.3. Interface between WG2 and WG5

Components of firework articles are usually sold by manufacturers to other manufacturers in some European

countries. WG 2 experts have considered “Category 4 firework articles” may include components of fireworks

such as stars, crackers, volcanoes, tourbillions, quick match, black match, cord igniters, fuses or delays…

from the point of view of Directive 2007/23/EC (See 2.1 here above).
WG 2 and WG 5 have met the following agreement:

 WG 5 will treat components of fireworks when they are used in other fields than fireworks (for example,

electric igniters, quick match, black match, cord igniters, pressed fuses, stars).

 When these components are strictly relevant to the fireworks market, they will enter into the scope of

work of WG2 (for example, crackers, volcanoes, tourbillions).
4 List of C4 Fireworks and definitions
4.1 Preliminary remarks

WG 1 dealing with “fireworks, categories 1, 2 and 3” has already elaborated drafts of harmonised standards

dealing with “Terminology” and “Categorization”. These documents include definitions of some articles which

will never have a C4 version and does not include definitions of articles which only exist as C4 fireworks

(“shells” for instance). However, these documents have been taken in account by WG 2 to assure the same

---------------------- Page: 10 ----------------------
SIST-TP CEN/TR 15951:2009
CEN/TR 15951:2009 (E)

definitions are used for the same types of articles by WG 1 and WG 2 as far as there are no justifiable

technical reasons to create differences or additions.

WG 2 experts have met the necessity to create such differences and additions in a number of cases, because:

 Some WG1 definitions include requirements which are specific to C1-C2-C3 Fireworks and must not be

imposed to C4 Fireworks as far as they are used by persons with specialized knowledge, e.g. cases of

C1-C2-C3 Fountains must be non metallic and the corresponding WG1 definition states it, but metallic

cases are already used for C4 Fountains and there is no major reason to forbid it.

 Requirements for C4 Fireworks do not need to be as precise, specific or numerous as for consumer

fireworks for they will only be used by persons with specialized knowledge. Then several types of firework

may be grouped under a more general type of firework or generic type, which simplifies the way design

and performance requirements will be set in the future harmonized standard(s). WG 2 experts have

decided to proceed to this grouping under some existing names of firework types and have consequently

adapted corresponding definitions.

The final list and definitions of types of C4 Fireworks will be a separate document from WG 1 Consumer

Fireworks Terminology and Categorization standards.
4.2 Criteria used to determine “generic types”

Criteria which have been used to determine “generic types” result directly from definition given here above to

this term (See 2.2). A first list of possible C4 fireworks sharing similar, but general, design features and “space

x time” performance characteristics has been drawn up. By “space x time”, WG 2 experts mean a pyrotechnic

effect or a sequence of pyrotechnic effects spreading progressively in the air during a given time.

Considering this list was exhibiting too many entries (45 distinct C4 fireworks, 14 C1-C2-C3 fireworks and 12

components), WG 2 experts have decided to simplify their approach of “generic types” after having taken

notice that:

 the essential safety requirements of Directive 2007/23/EC will only necessitate to determine requirements

on a limited number of design and performance characteristics, as far as C4 fireworks are used by

persons with specialist knowledge allowing them to assure safety of the public and protection of the

environment by application of well mastered rules and instructions resulting from their experience and

training;

 as a consequence of this limited number of design and performance characteristics, some possible

generic types can be generalized to encompass other possible generic types which can then be

considered as particular cases of these “generalised” generic types. For example, a “shot tube” is a

“roman candle” the sequence of which is limited to a single shot.

Doing this, WG 2 experts have determined 12 “generalised” firework products which will become the “generic

types” on which will be placed design and performance requirements in the future harmonized standard(s) for

C4 fireworks.

The other 34 remaining firework products will only be particular variants of these “generic types”, consequently

falling under the same design and performance requirements. To keep things clear, WG 2 experts have

chosen to call them “sub types”.

The original list of firework products has then been split into three distinct lists: list of generic types (See 4.3),

list if subtypes (See 4.4) and list of components (See 4.5)
4.3 Generic types: list and definitions
The following 12 generic types have been selected:
 Aerial Wheel

 Fountain
 Guided Firework
 Mine
 Report

 Shell
 Smoke / Fog Generator

For corresponding definitions, comments and description of principal effects, see Annex A.

4.4 Other types of firework: list, definitions and links to generic types

The following 33 firework products have been considered as subtypes of the previous generic types:

Aqua Shell (or Aquatic Shell, Nautical Shell), Bag Mine (or Mortar Mine), Battery, Bengal Flame, Cake,

Daylight Shell, Flash Banger, Flight Rocket, Gerbs, Ground Maroon, Lance, Lancework, Maroon, Maroon

Shell, Multibreak Shell, Parachute Rocket, Parachute Shell, Peanut Shell, Portfire, Preloaded mortar (or Shell

in mortar), Repeater Shell, Saxon, Set Piece, Shell of shells, Shot tube, Signal Rocket, Strobe, Tourbillion,

Underwater Firework (or Sub aquatic firework), Volcano, Waterfall, Wheel.

For corresponding definitions, links to generic types and description of principal effects, see Annex B.

4.5 Components: list and definitions

The following list is limited to pyrotechnic components which can be placed on the market and exchanged

between industrialists throughout Europe. These components are not only intended for use by fireworks

manufacturers, but can also be used – under given conditions – by persons with specialist knowledge which

will be trained accordingly.

Bombette, Butterfly, Cracker, Fuse (including Delay Fuse), Motor, Serpent, Spinner, Star (including Comet,

Crossette, Flash Pellet, Hummer and Whistle).
This list of components is not exhaustive.

For corresponding definitions, comments and description of principal effects, see Annex C.

For the specific case of “stars”, see Annex D.

SIST-TP CEN/TR 15951:2009
CEN/TR 15951:2009 (E)
4.6 Specific uses of articles
Special use of C1, C2 and C3 products:

C1, C2 and C3 articles may be used by persons with specialist knowledge in a different way that required and

type-certified as “customer” fireworks. This possibility must be introduced as acceptable in a C4 standard,

provided that the persons with specialist knowledge evaluate the new safety distances corresponding to their

special use of the articles on the basis of performance characteristics to be supplied with the articles (label

and/or “data sheet”).
Dual use:

Some products may have a dual use: outdoor fireworks and indoor / theatrical pyrotechnic articles, without

any modifications or adaptations. In that case, it seems logical to WG 2 experts that they must be type-

certified under the category corresponding to their most restricting use. For example, a T2 article may be

generally used in a fireworks display as a C4 product without being C4 type-certified, but the contrary may not

be possible.
4.7 Recommendations for integration of new items

Lists of generic types and subtypes given in Annexes A and B may not be fully exhaustive and correspond to

the present knowledge of WG 2 experts. New items may be identified during the development phase or after

the publication of C4 fireworks harmonized standard(s).
During the development phase:

Every new item will be compared by WG 2 experts to existing generic types and subtypes in the lists given in

Annex A and Annex B. If it can be considered as a variant of an existing generic type or subtype, it will not be

necessary to add it to these lists. In the opposite case and if it is not specific to one manufacturer or importer,

the new item will lead either to the creation of a new subtype linked to an existing generic type or to the

creation of a new generic type.

If the new item is specific to one manufacturer or importer, it will not be encompassed by the C4 fireworks

harmonized standard(s) in development and its CE type-certification process will be determined by the

Notified Body of one Member State.
After publication of harmonised standards:

If the new item is specific to one manufacturer or importer, its CE type-certification process will be determined

by the Notified Body of one Member State.

Alternatively, the first Notified Body which will identify the new item will compare it to the lists of generic types

and subtypes which will be part of C4 fireworks harmonized standard(s). If it can be considered as a variant of

an existing generic type or subtype, no update of the harmonized standard(s) will be needed. If not, the

Notified Body will propose to the Notified Bodies of the other Member States to ask CEN for a modification of

the harmonized standards. Then the normal CEN process for updating standards will apply.
