11、4 Introduction Mandate M416 is issued by the European Commission to CEN. The main reason for this mandate is the fact that on 14 June 2007, Directive 2007/23/EC of the European Parliament and of the Council on the placing on the market of pyrotechnic articles, was published in the Official Journal.

12、In Annex 1 of Directive 2007/23/EC the essential safety requirements for pyrotechnic articles are given. In order to facilitate the process of demonstrating compliance with the essential safety requirements, harmonized standards for the design, manufacture and testing of pyrotechnic articles have to

13、 be developed. Mandate M 416 describes the work that the EC wants CEN to perform. During its meeting in Delft, October 2007, CEN/TC 212 has decided to share the corresponding work to be done between five Working Groups of which WG 4 for “Pyrotechnic articles for vehicles“. At its plenary meeting in

14、Berlin, May 2008, CEN 212 has agreed to produce, as a first step, a report presenting the results of the work presently done and describing the next steps for developing EN standards. PD CEN/TR 15970:2009 CEN/TR 15970:2009 (E) 5 1 Scope This Technical Report gives a description of the context regard

15、ing the situation of pyrotechnic articles for vehicles and their consideration within the Directive 2007/23/EC with the aim to define what harmonized standards shall be developed in order to comply with the essential safety requirements of the Annex 1 of the Directive. 2 Description of the context T

16、he Directive 2007/23/EC for the placing on the market of pyrotechnic articles clearly includes pyrotechnic articles for vehicles (see article 2 item 5 of the Directive). CEN has received a mandate for the development of harmonised standards for pyrotechnic articles. Therefore during the first CEN/TC

17、212 meeting in October 2007 a working group (WG4) was established dedicated to the development of standards for pyrotechnic articles in vehicles. An agreement between CEN and ISO on technical cooperation between ISO and CEN from 1991 (Vienna agreement) makes it necessary to carefully inspect all ava

18、ilable material on the ISO-level which may influence or may be reused for the standardisation of pyrotechnic articles. Specifically this is ISO 12097, where parts may be very useful in order to use a compatible terminology and/or testing regime. Pyrotechnics articles for vehicles are produced worldw

19、ide for installation in vehicles manufactured in Europe or as spare parts on running vehicles within Europe. Some pyrotechnic articles for vehicles can be regarded intermediate products, which will only enter further production steps, while some pyrotechnic articles for vehicles are directly install

20、ed into a vehicle, e.g. as a replacement part but also during vehicle assembly. This indicates that pyrotechnic articles for vehicles are subject to different levels of professional use. Pyrotechnic substances are found in vehicle components such as airbags, seatbelt-pretensioners, circuit breakers,

21、 and various mechanical actuators. Parts, which are traded between suppliers and original equipment manufacturers (OEM), can be seen on all levels from the most basic units, i.e. the igniters or micro- gasgenerators for a pyrotechnical mechanism, to very complex units, such as an airbag module with

22、specific mounting features and a model specific cover plate. As the parts become more sophisticated (from the igniter to a module) often also a wider range of variants exist, with every part being adjusted to the huge range of vehicle models and/or production years. In order to limit the burden of t

23、esting and certification, both on the side of the industry and on the side of certifying bodies, it will be necessary to develop suitable principles for grouping of articles. The Directive makes explicit reference to this aspect by stating in the initial considerations that “Groups of pyrotechnic ar

24、ticles that are similar in design, function or behaviour should be assessed by the notified bodies as product families“ (consideration no. 18). The standards to be developed will not try to solve the problem of a difficult to overlook variety, and will not specify articles through every possible det

25、ail. The standards will have to describe basic concepts and principal types of pyrotechnic articles. Furthermore the standards will describe test methods which are meant to cover the essential safety requirements (ESR, see Annex I of the Directive) as set out in the Directive. The standards will not

26、 cover performance relevant properties outside the scope of the ESR; they will however try to include as much overlap as possible with existing performance oriented standards (see above, link to ISO). The categorisation into P1 and P2 articles will have effects on the handling of such articles in th

27、e context of production or vehicle repair. The definition of the boundary between P1 and P2 will have to take this into account while implementing the given, even though relatively vague, definition (“P1: pyrotechnic articles which present a low hazard ;“) of the Directive. PD CEN/TR 15970:2009 CEN/

28、TR 15970:2009 (E) 6 3 Interface between CEN/TC 212 Working groups For a connection between WG4 and WG5 it was decided to have a liaison person. WG4 experts consider igniters used as components in airbags generators and other automotive pyrotechnic devices must enter in the field of “pyrotechnic arti

29、cles for vehicles” since they are specially designed for automotive applications. In that case, WG4 will create the corresponding standard and automotive igniters will not be taken in account by WG5. Such igniters may be used without modification or adaptation in other applications than automotive.

30、WG4 and WG5 experts agree on the following approach: Because WG5 and WG4 shall prepare separate standards for electric igniters, a comparison of these two standards will be made to determine what standard the most restrictive will be applicable when electric igniters developed for automotive industr

31、y are used outside this industry. In every case, igniters which will have been submitted to type-examination according to the more restrictive harmonized standard will not need to be submitted again to type-examination for all less demanding applications. 4 The harmonized EN Standards 4.1 Aim In ord

32、er to facilitate the process of demonstrating compliance with the essential safety requirements set out in the annex I of the Directive 2007/23/EC, harmonised standards for the design, manufacture and testing of pyrotechnic articles shall be drawn up and adopted by competent organisations. The Europ

33、ean Commission (EC) has then request the Committee for European Standardization (CEN) through its Technical Committee (TC) 212 “Pyrotechnic Articles” to do so. 4.2 The standard to be performed for pyrotechnical articles for vehicles During drafting the harmonised standards, the international orienta

34、tion of the European vehicle supply industry should be reflected by taking into account the relevant international ISO standards for pyrotechnic articles for vehicles subject to the directive. That will be achieved by using existing relevant ISO test methods with no or minor adjustments. The proposa

35、l is to draft a standard structured with different parts. So far, the following parts have been identified: prEN xxxxx-1: “Pyrotechnic articles for vehicles - Part 1: Terminology”; prEN xxxxx-2: “Pyrotechnic articles for vehicles - Part 2: Test methods”; prEN xxxxx-3: “Pyrotechnic articles for vehic

36、les - Part 3: Labelling; prEN xxxxx-4: “Pyrotechnic articles for vehicles - Part 4: Requirements for micro gas generators”; prEN xxxxx-5: “Pyrotechnic articles for vehicles - Part 5: Requirements for airbag gas generators”; prEN xxxxx-6: “Pyrotechnic articles for vehicles - Part 6: Requirements for

37、air bag modules”; prEN xxxxx-7: “Pyrotechnic articles for vehicles - Part 7: Requirements for seatbelt pretensioners”; prEN xxxxx-8: “Pyrotechnic articles for vehicles - Part 8: Requirements for igniters“; PD CEN/TR 15970:2009 CEN/TR 15970:2009 (E) 7 prEN xxxxx-9: “Pyrotechnic articles for vehicles

38、- Part 9: Requirements for actuators”; prEN xxxxx-10: “Pyrotechnic articles for vehicles - Part 10: Requirements for semi-finished assemblies”. This structure with a common part for definitions (part 1), a common part for test methods (part 2) and different parts for tests conditions and requirement

39、s according to the type of article is found the most suitable for several reasons. Firstly, it is clear for everybody that in order to understand each other and speak the same language it is necessary to define the technical terms as precisely as possible. These definitions will be gathered on the s

40、ame document and be applicable to all documents drafted. Secondly, it was decided to prepare a limited number of test methods (as much as possible based on ISO standards). Therefore, these test methods can be described in a single manageable document. Then depending of the type of articles, the need

41、ed test methods will be picked from that set of procedures for the assessment toward the essential safety requirements. Thirdly, different pyrotechnical articles for vehicles were already identified and classified by the WG4 in types according to their general typical uses. As for a same test method

42、 it is likely a necessity to fix slightly different test conditions and requirements to match the different type of articles, these conditions and requirements will be described in separate parts of the standard. Moreover, if in the future a new type of articles appears on the market it will be easy

43、 to add to the standard a new part corresponding to the test conditions and requirements for this new type. Criteria for categorisation in P1 and P2 will be defined in parts 4 to 10. Various parts for different articles will give tables showing the test methods to be used, the number of samples to b

44、e tested and the order of consecutive testing when necessary. The links between the test methods and the essential safety requirements of the Directive will also be annexed to each part. 4.3 The work in progress So far, the CEN/TC 212/WG 4 has focussed its works on the following points: identificati

45、on, definition and classification the different articles for vehicles that might be subject to the Directive 2007/23/EC; discussion on the scope of the Directive to clarify which pyrotechnical articles for vehicles are concerned and which are not and establishment of two lists of articles (in/out of

46、 the scope); selection and drafting of the general test methods to be used.
