(Main)Fire hazard testing - Part 2-12: Glowing/hot-wire based test methods - Glow-wire flammability index (GWFI) test method for materials (IEC 60695-2-12:2021)
Fire hazard testing - Part 2-12: Glowing/hot-wire based test methods - Glow-wire flammability index (GWFI) test method for materials (IEC 60695-2-12:2021)
This part of IEC 60695 specifies the details of the glow-wire test to be applied to test
specimens of solid electrical insulating materials or other solid materials for flammability
testing to determine the glow-wire flammability index (GWFI).
GWFI is the highest temperature, determined during this standardized procedure, at which the
tested material does not ignite or, if it does, extinguishes within 30 s after removal of the
glow-wire and is not totally consumed; and molten drips, if they occur, do not ignite the
wrapping tissue.
This test method is a materials test carried out on a series of standard test specimens. The
data obtained, along with data from the glow-wire ignition temperature (GWIT) test method for
materials, IEC 60695-2-13, can then be used in a preselection process in accordance with
IEC 60695-1-30 [4] to judge the ability of materials to meet the requirements of
IEC 60695-2-11.
NOTE As an outcome of conducting a fire hazard assessment, an appropriate series of preselection flammability
and ignition tests can allow a reduction of end product testing.
This basic safety publication focusing on safety test method(s) is primarily intended for use by
technical committees in the preparation of safety publications 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.

Essais relatifs aux risques du feu - Partie 2-12: Essais au fil incandescent/chauffant - Méthode d'essai d'indice d'inflammabilité au fil incandescent (GWFI) pour matériaux (IEC 60695-2-12:2021)
IEC 60695-2-12:2021 est disponible sous forme de IEC 60695-2-12:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
IEC 60695-2-12:2021 décrit les informations détaillées de l’essai au fil incandescent destiné à être appliqué à des éprouvettes d’essai de matériaux isolants électriques solides ou autres matériaux solides pour les essais d’inflammabilité dans le but de déterminer l’indice d’inflammabilité au fil incandescent (GWFI, glow-wire flammability index). Le GWFI est la température la plus élevée, déterminée durant cette procédure normalisée, à laquelle le matériau en essai ne s’enflamme pas ou s’il s’enflamme, s’éteint dans les 30 s qui suivent le retrait du fil incandescent et n’est pas entièrement consumé; et des gouttes en fusion, s’il y a lieu, n’enflamment pas le papier mousseline. Cette méthode d’essai est un essai de matériaux exécuté sur une série d’éprouvettes d'essai normalisées. Les données obtenues, ainsi que les données issues de la méthode d’essai de température d’allumabilité au fil incandescent (GWIT, glow-wire ignition temperature) pour matériaux, IEC 60695-2-13, peuvent alors être utilisées dans un processus de présélection conformément à l’IEC 60695 1 30 [4] pour estimer l'aptitude des matériaux à satisfaire aux exigences de l’IEC 60695 2 11. La présente publication fondamentale de sécurité, fondée sur la ou les méthodes d'essai de sécurité, est essentiellement destinée à être utilisée par les comités d’études dans le cadre de l’élaboration de publications de sécurité conformément aux principes établis dans le Guide IEC 104 et 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. Cette norme doit être utilisée conjointement avec l’IEC 60695-2-10. Cette troisième édition annule et remplace la deuxième édition parue en 2010 et l'Amendement 1:2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) ajout à l’Article 3 de nouveaux termes et définitions, ayant rapport aux moments et durées, applicables à la méthode d'essai.
Preskušanje požarne ogroženosti - 2-12. del: Preskusne metode z žarilno žico - Preskusna metoda za materiale: indeks vnetljivosti z žarilno žico (GWFI) (IEC 60695-2-12:2021)
Ta del standarda IEC 60695 podrobno določa preskus z žarilno žico, ki se uporablja za preskušance trdnih električnih izolacijskih materialov ali drugih trdnih materialov za preskus vnetljivosti, s katerim se določi indeks vnetljivosti z žarilno žico (GWFI). Indeks vnetljivosti z žarilno žico je najvišja temperatura, določena med tem standardiziranim postopkom, pri kateri se preskušeni material ne vname, oziroma če se vname, plamen ugasne v 30 sekundah po odstranitvi žarilne žice in material ne izgori v celoti, staljene kapljice, če se pojavijo, pa ne zanetijo ovojnega tkiva. Ta preskusna metoda vključuje preskus materialov, ki se izvede na več standardnih preskušancih. Pridobljene podatke je mogoče nato skupaj s podatki iz preskusne metode za materiale z indeksom vnetljivosti z žarilno žico (IEC 60695-2-13) uporabiti v predizbirnem postopku v skladu s standardom IEC 60695-1-30 [4], da se oceni zmožnost materialov za izpolnjevanje zahtev standarda IEC 60695-2-11. OPOMBA: Kot rezultat ocenjevanja požarne ogroženosti je mogoče z ustreznim naborom predizbirnih preskusov vnetljivosti in vžiga zmanjšati število preskusov končnega izdelka. Ta osnovna varnostna publikacija, ki se osredotoča na varnostne preskusne metode, je namenjena predvsem tehničnim odborom za pripravo varnostnih publikacij v skladu z načeli vodil IEC 104 in ISO/IEC 51. Ena od dolžnosti tehničnega odbora je, da med pripravo publikacij uporablja osnovne varnostne publikacije, kadar je to primerno.

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.
IEC 60695-2-12 has been prepared by IEC technical committee 89: Fire hazard testing. It is
an International Standard.
This third edition cancels and replaces the second edition published in 2010 and
Amendment 1:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) New terms and definitions with regards to times and durations have been added to
Clause 3, with an effect on the application of the test method.
