Fire hazard testing - Part 9-2: Surface spread of flame - Summary and relevance of test methods

IEC 60695-9-2:2021 presents a summary of published test methods that are used to determine the surface spread of flame of electrotechnical products or materials from which they are formed. It represents the current state of the art of the test methods and, where available, includes special observations on their relevance and use. The list of test methods is not to be considered exhaustive, and test methods that were not developed by the IEC are not to be considered as endorsed by the IEC unless this is specifically stated. This summary cannot be used in place of published standards which are the only valid reference documents. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications. This International Standard is to be used in conjunction with IEC 60695-1. This second edition cancels and replaces the first edition of IEC 60695-9-2 published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Updated introduction b) Updated normative references c) Updated terms and definitions d) New Subclauses 4.1 and 4.2 e) Reference to fire stages as defined in ISO 19706 (Table 1) f) New sub-division of tests into the following subclauses: 4.3 Small-scale fire tests 4.4 Medium and intermediate-scale fire tests 4.5 Intermediate and large-scale fire tests for cables 4.6 Real-scale fire tests for cables g) Updated text in parts of Clause 4 h) Addition of the following test methods: IEC TS 60695-11-21 IEC 60684-2:2011, Clause 26 ISO 3582 ISO 9772 ISO 9773 ISO 12992 ISO 21367 i) New Clause 5 and Table 4 giving an overview of test methods j) Deletion of all the Annexes k) Updated bibliography

Prüfungen zur Beurteilung der Brandgefahr - Teil 9-2: Flammenausbreitung auf Oberflächen - Zusammenfassung und Anwendbarkeit der Prüfverfahren

Essais relatifs aux risques du feu - Partie 9-2: Propagation des flammes en surface - Résumé et pertinence des méthodes d'essai

IEC 60695-9-2:2021 propose un résumé des méthodes d'essai publiées utilisées pour déterminer la propagation de flamme en surface des produits électrotechniques ou des matériaux dont ils sont constitués. Elle représente l'état actuel de l'art des méthodes d'essai et, le cas échéant, elle comprend des observations particulières sur leur pertinence et leur utilisation. La liste des méthodes d’essai ne doit pas être considérée comme exhaustive, et les méthodes d'essai qui n'ont pas été élaborées par l’IEC ne doivent pas être considérées comme étant entérinées par l’IEC, sauf si cela est spécifiquement stipulé. Ce résumé ne peut pas se substituer aux normes publiées, qui sont les seuls documents de référence valables. Cette publication fondamentale de sécurité est destinée à être utilisée par les comités d’études pour l’établissement de leurs normes, conformément aux principes exposés dans le Guide IEC 104 et dans le Guide ISO/IEC 51. L'une des responsabilités d'un comité d'études consiste, le cas échéant, à utiliser les publications fondamentales de sécurité dans le cadre de l'élaboration de ses publications. Les exigences, les méthodes d'essai ou les conditions d'essai indiquées dans la présente publication fondamentale de sécurité ne s'appliquent que si elles sont référencées ou incluses dans les publications appropriées. Cette Norme internationale doit être utilisée conjointement avec l’IEC 60695-9-1. Cette deuxième édition annule et remplace la première édition de l’IEC 60695-9-2 parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) Mise à jour de l’introduction b) Mise à jour des références normatives c) Mise à jour des termes et définitions d) Nouveaux Paragraphes 4.1 et 4.2 e) Référence aux stades d’incendie tels qu'ils sont définis dans l’ISO 19706 (Tableau 1) f) Nouvelle répartition des essais dans les paragraphes suivants: 4.3 Essais au feu à petite échelle 4.4 Essais au feu à échelles moyenne et intermédiaire 4.5 Essais au feu à échelle intermédiaire et à grande échelle pour les câbles 4.6 Essais au feu en grandeur réelle pour les câbles g) Mise à jour du texte de certaines parties de l’Article 4 h) Ajout des méthodes d'essai suivantes: IEC TS 60695-11-21 IEC 60684-2:2011, Article 26 ISO 3582 ISO 9772 ISO 9773 ISO 12992 ISO 21367 i) Nouvel Article 5 et nouveau Tableau 4 qui donnent une vue générale des méthodes d'essai j) Suppression de toutes les Annexes k) Mise à jour de la bibliographie

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
