IEC 60695-8-2:2016

Fire hazard testing - Part 8-2: Heat release - Summary and relevance of test methods

IEC 60695-8-2:2016 presents a summary of published test methods that are relevant to the determination of the heat released in fire tests on 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. Heat release data can be used as part of fire hazard assessment and in fire safety engineering, as discussed in IEC 60695-1-10, IEC 60695-1-11 and IEC 60695-1-12. This standard is to be used in conjunction with IEC 60695-8-1.
Key words: Fire Hazard, Heat Release, Fire Safety Engineering, Test Methods

Essais relatifs aux risques du feu - Partie 8-2: Dégagement de chaleur - Résumé et pertinence des méthodes d'essais

L'IEC 60695-8-2:2016 présente un résumé des méthodes d'essai publiées pertinentes pour la détermination du dégagement de chaleur dans les essais au feu réalisés sur les produits électrotechniques ou les matériaux à partir desquels ils sont constitués. Elle représente l'état actuel de la technique des méthodes d'essai et, le cas échéant, comprend des observations particulières portant sur leur pertinence et utilisation. La liste des méthodes d'essai ne doit pas être considérée comme étant exhaustive, et les méthodes d'essai non élaborées par l'IEC ne doivent pas être considérées comme entérinées par ce dernier sauf indication spécifique. Les données de dégagement de chaleur peuvent être utilisées comme partie intégrante de l'évaluation du danger d'incendie et pour l'ingénierie de la sécurité incendie, comme indiqué dans l'IEC 60695-1-10, l'IEC 60695-1-11 et l'IEC 60695-1-12. Cette Norme internationale doit être utilisée conjointement avec l'IEC 60695-8-1.

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.
International Standard IEC 60695-8-2 has been prepared by IEC technical committee 89: Fire
hazard testing.
This first edition cancels and replaces IEC TR 60695-8-2 published in 2008. This edition
constitutes a technical revision.
The text of this International Standard is based on the following documents:
FDIS Report on voting
89/1343/FDIS 89/1349/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

– 4 – IEC 60695-8-2:2016 © IEC 2016
It has the status of a basic safety publication in accordance with IEC Guide 104 and
ISO/IEC Guide 51.
A list of all the parts in the IEC 60695 series, under the general title Fire hazard testing, can
be found on the IEC website.
This International Standard is to be used in conjunction with IEC 60695-8-1.
IEC 60695-8 consists of the following parts:
• Part 8-1: Heat release – General guidance
• Part 8-2: Heat release – Summary and relevance of test methods
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the da
