Fire hazard testing - Part 1-40: Guidance for assessing the fire hazard of electrotechnical products - Insulating liquids
IEC 60695-1-40:2013 provides guidance on the minimization of fire hazard arising from the use of electrical insulating liquids, with respect to:
- electrotechnical equipment and systems and
- people, building structures and their contents.
It is not intended for use by manufacturers or certification bodies. This first edition of IEC 60695-1-40 cancels and replaces the first edition of IEC/TS 60695-1-40 published in 2002. It constitutes a technical revision and now has the status of an International Standard. The main changes with respect to the first edition of IEC/TS 60695-1-40 are the integration of editorial and technical changes throughout the text. Key words: Fire testing, fire hazard, insulating liquids
This publication is to be read in conjunction with IEC 60695-1-10:2009.
Essais relatifs aux risques du feu - Partie 1-40: Guide pour l'évalution des risques du feu des produits électrotechniques - Liquides isolants
La IEC 60695-1-40:2013 fournit des lignes directrices pour la minimisation du danger d'incendie dans le cadre de l'utilisation de liquides isolants électriques:
- pour les équipements et systèmes électrotechniques et pour les personnes,
- les structures des bâtiments et leur contenu.
Elle n'est pas destinée à être utilisée par les fabricants ou les organismes de certification. Cette première édition de la CEI 60695-1-40 annule et remplace la première édition de la CEI/TS 60695-1-40 publiée en 2002. Elle constitue une révision technique et a désormais le statut d'une Norme internationale. Les principales modifications apportées par rapport à la première édition de la CEI/TS 60695-1-40 sont l'intégration de modifications rédactionnelles et techniques dans tout le texte. Mots-clés: essais au feu, danger d'incendie, liquides
Cette publication doit être lue conjointement avec la CEI 60695-1-10:2009.

Part 1-40: Guidance for assessing the fire hazard
of electrotechnical products –
Insulating liquids
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 b
