IEC 60695-1-10:2016

Fire hazard testing - Part 1-10: Guidance for assessing the fire hazard of electrotechnical products - General guidelines

IEC 60695-1-10:2016 provides general guidance with respect to fire hazard testing on how to reduce to a tolerable level the risk of fire and the potential effects of fires involving electrotechnical products. It also serves as a signpost standard to the other guidance publications in the IEC 60695 series. It does not give guidance on the use of fire-resistant compartment boundaries or on the use of detection and suppression systems for the mitigation of fire risk. It describes the relationship between fire risk and the potential effects of fire, and provides guidance to IEC product committees on the applicability of qualitative and quantitative fire tests to the fire hazard assessment of electrotechnical products. Details of the calculation of fire risk are not included in the scope of this document. It emphasises the importance of the scenario approach to fire hazard and risk assessment and discusses criteria intended to ensure the development of technically sound hazard-based fire test methods. It discusses the different types of fire tests, in particular the nature of qualitative and quantitative fire tests. It also describes the circumstances under which it is appropriate for IEC product committees to maintain or develop qualitative fire tests. This standard is intended as guidance to IEC committees, and is to be used with respect to their individual applications. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- reference to IEC 60695-1-12;
- modified Introduction and Scope;
- updated normative references;
- updated terms and definitions;
- modified Table 1;
- addition of Table 2;
- new text in Subclauses 5.2, 5.3 and 5.4;
- mandatory text in Clause 8;
- Annex B changed to Annex A, and modified;
- new Annex B concerning common ignition sources.
This publication is to be read in conjunction with IEC 60695-1-11:2014 and IEC 60695-1-12:2015.
Key words: Fire Hazard, Fire Risk, Fire Safety Engineering

Essais relatifs aux risques du feu - Partie 1-10: Lignes directrices pour l'évaluation des risques du feu des produits électrotechniques - Lignes directrices générales

L'IEC 60695-1-10:2016 fournit des lignes directrices générales concernant les essais relatifs aux dangers d'incendie, sur la manière de réduire à un niveau acceptable le risque d'incendie et les effets potentiels des incendies impliquant des produits électrotechniques. Elle sert aussi de norme de référence pour les autres publications donnant des lignes directrices dans la série IEC 60695. La présente partie ne fournit pas de lignes directrices relatives à l'utilisation de parois de compartiment résistant au feu ou de systèmes de détection et de suppression pour la réduction du risque d'incendie. Elle décrit la relation entre le risque d'incendie et les effets potentiels des incendies. Elle fournit des lignes directrices aux comités de produits de l'IEC sur la pertinence des essais au feu qualitatifs et quantitatifs pour l'évaluation des dangers d'incendie des produits électrotechniques. Les détails du calcul du risque d'incendie ne sont pas couverts par le domaine d'application du présent document. Elle souligne l'importance de l'approche par scénario pour l'évaluation des dangers d'incendie et des risques d'incendie. Elle traite également des critères visant à assurer le développement de méthodes d'essai au feu basées sur les dangers qui soient techniquement solides. Elle traite des différents types d'essais au feu et, en particulier, de la nature des essais qualitatifs et quantitatifs. Elle décrit aussi les circonstances pour lesquelles il est approprié pour les comités de produits de l'IEC de maintenir ou de mettre au point des essais au feu qualitatifs. La présente norme est destinée à fournir des lignes directrices pour les comités de l'IEC et il convient de les utiliser en fonction de leurs applications particulières. Cette deuxième édition annule et remplace la première édition parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- référence à l'IEC 60695-1-12;
- modification de l'introduction et du domaine d'application;
- mise à jour des références normatives;
- mise à jour des termes et définitions;
- modification du Tableau 1;
- ajout du Tableau 2: nouveau texte dans les Articles 5.2, 5.3 et 5.4.;
- texte obligatoire à l'Article 8;
- annexe B renommée Annexe A, et modifiée et ajout d'une Annexe B relative aux sources d'allumage communes.
Cette publication doit être lue conjointement avec la IEC 60695-1-11:2014, et IEC 60695-1-12:2015.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.
