Essais relatifs aux risques du feu -- Partie 11-5: Flammes d'essai - Méthode d'essai au brûleur-aiguille - Appareillage, dispositif d'essai de vérification et lignes directrices

Spécifie un essai au brûleur-aiguille pour simuler l'effet d'une petite flamme qui peut provenir de conditions de défaut, afin d'évaluer par simulation le risque du feu. Elle est applicable aux matériels électrotechniques, à leurs sous-ensembles et à leurs composants et aux matériaux isolants électriques solides ou à d'autres matériaux combustibles. Cette première édition de la EN 60695-11-5 annule et remplace la deuxième édition de la EN 60695-2-2 publiée en 1991 et son amendement 1 (1994). Elle en constitue une révision technique. La structure de cette norme reste essentiellement la même avec l'ajout de plusieurs modifications et concepts majeurs: - Le domaine d'application de la présente méthode d'essai a été élargi pour simuler les effets des petites flammes d'origine externe à l'équipement. - Un nouveau concept a été ajouté qui permet le déplacement du brûleur au cours de l'essai pour éviter que du matériau qui s'écoule tombe sur l'extrémité du tube du brûleur. - Le matériau du tube du brûleur est maintenant une source référencée. - La référence pour le matériau du bloc de cuivre a changé - la publication ISO a été supprimée (ISO 1337) sans remplacement et une nouvelle désignation est désormais utilisée. - L'Annexe informative B et une bibliographie ont été ajoutées. Elle a le statut de publication fondamentale de sécurité, conformément au Guide CEI 104

Part 11-5: Test flames – Needle-flame test method – Apparatus, confirmatory test arrangement and guidance

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60695-11-5 has been prepared by IEC technical committee 89: Fire hazard testing. This first edition of IEC 60695-11-5 cancels and replaces the second edition of IEC 60695-2-2, issued in 1991 and its amendment 1 (1994). It also constitutes a technical revision.

A new callout is now used. – Informative Annex B and a bibliography have been added. It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. The text of this standard is based on the following documents: FDIS Report on voting 89/676/FDIS 89/679/RVD

INTRODUCTION The best method for testing electrotechnical products with regard to fire hazard is to duplicate exactly the conditions occurring in practice. In most instances this is not possible. Accordingly, for practical reasons, the testing of electrotechnical products with regard to fire hazard is best conducted by simulating as closely as possible the actual effects occurring in practice. Parts of electrotechnical equipment which might be exposed to excessive thermal stress due to electric effects, the deterioration of which might impair the safety of the equipment, should not be unduly affected by heat and by fire generated within the equipment. Parts of insulating material or of other combustible material which are liable to propagate flames inside the equipment may be ignited by flames produced by a failing component. Under certain conditions, for example a fault current flowing over a tracking path, overloading of components or parts and bad connections, flames may also occur; such flames may impinge upon combustible parts in the vicinity. This part of IEC 60695 should be used to measure and describe the properties of materials, products or assemblies in response to
