IEC 60695-2-13:2010

Fire hazard testing - Part 2-13: Glowing/hot-wire based test methods - Glow-wire ignition temperature (GWIT) test method for materials

IEC 60695-2-13:2010 specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for ignitability testing to determine the glow-wire ignition temperature (GWIT). The GWIT is the temperature which is 25 K (or 30 K) higher than the maximum test temperature, determined during this standardized procedure, at which the tested material does not ignite, or if sustained and continuous flaming combustion does not occur for a time longer than 5 s for any single flame event and the specimen is not totally consumed. This second edition of IEC 60695-2-13 cancels and replaces the first edition published in 2000. It also constitutes a technical revision. The main changes with respect to the previous edition are:
- modified title;
- addition of an Introduction;
- clarification of Scope;
- expansion of Clause 2: Normative references;
- expansion of Clause 3;
- revision of Clause 4 to alignment with the IEC 60695-11 series to introduce guidance on test programs for material variations;
- clarification of Clause 8: Conditioning (now Clause 7);
- deletion of Clause 9: Initial measurement;
- expansion of Clause 10: Test procedures (now Clause 8);
- expansion of Clause 11: Observation and measurement (now Clause 9);
- clarification of Clause 12: Evaluation of test results (now Clause 10);
- expansion of Clause 13: Test report (now Clause 11).
This publication is to be read in conjunction with IEC 60695-2-10:2000. The contents of the corrigendum of February 2012 have been included in this copy.

Essais relatifs aux risques du feu - Partie 2-13: Essais au fil incandescent/chauffant - Méthode d'essai de température d'allumabilité au fil incandescent (GWIT) pour matériaux

La CEI 60695-2-13:2010 spécifie les détails de l'essai au fil incandescent quand il est appliqué à des éprouvettes d'essai de matériaux isolants électriques solides ou autres matériaux solides pour les essais d'allumabilité dans le but de déterminer la température d'allumage au fil incandescent (GWIT, glow-wire ignition temperature). La GWIT est la température qui est supérieure de 25 K (ou 30 K) à la température d'essai maximale, déterminée durant cette procédure normalisée, à laquelle le matériau essayé, ne s'enflamme pas, ou si une combustion d'inflammation entretenue et continue ne se produit pas pendant une durée supérieure à 5 s suite à un événement d'inflammation unique quelconque et si l'éprouvette d'essai n'est pas entièrement consumée. Cette deuxième édition de la CEI 60695-2-13 annule et remplace la première édition parue en 2000 dont elle constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont:
- modification du titre;
- ajout d'une Introduction;
- clarification du Domaine d'application;
- extension de l'Article 2: Références normatives;
- extension de l'Article 3;
- révision de l'Article 4 pour alignement avec la série CEI 60695-11 afin d'introduire des lignes directrices concernant les programmes d'essai pour les variations de matériaux;
- clarification de l'Article 8: Conditionnement (désormais Article 7);
- suppression de l'Article 9: Mesures initiales;
- extension de l'Article 10: Méthodes d'essai (désormais Article 8);
- extension de l'Article 11: Observations et mesures (désormais Article 9);
- clarification de l'Article 12: Evaluation des résultats de l'essai (désormais Article 10);
- extension de l'Article 13: Rapport d'essai (désormais Article 11).
Cette publication doit être lue conjointement avec la CEI 60695-2-10:2000. Le contenu du corrigendum de février 2012 a été pris en considération dans cet exemplaire.

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 60695-2-13 has been prepared by technical committee 89: Fire
hazard testing.
This second edition of IEC 60695-2-13 cancels and replaces the first edition published in 2000.
It also constitutes a technical revision.
It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC
Guide 51.
This standard is to be used in conjunction with IEC 60695-2-10.
The main changes with respect to the previous edition are listed below:
– modified title;
– addition of an Introduction;
– clarification of Scope;
– 4 – 60695-2-13  IEC:2010
– expansion of Clause 2: Normative references;
– expansion of Clause 3;
– revision of Clause 4 to alignment with the IEC 60695-11 series to introduce guidance on
test programs for material variations;
– clarification of Clause 8: Conditioning (now Clause 7);
– deletion of Clause 9: Initial measurement;
– expansion of Clause 10: Test procedures (now Clause 8);
– expansion of Clause 11: Observation and measurement (now Clause 9);
– clarification of Clause 12: Evaluation of test results (now Clause 10);

89/1018/FDIS 89/1035/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
