Fire hazard testing - Part 2-11: Glowing/hot-wire based test methods - Glow-wire flammability test method for end products (GWEPT)

This part of IEC 60695 specifies a test method on an end product. It is intended to simulate the effects of thermal stresses produced by an electrically heated source to represent a fire hazard. This test method is used to check that, under defined test conditions, an end product exposed to an electrically heated source has either a limited ability to ignite or, if it ignites, a limited ability to propagate flame. However, the fire hazard analysis, the flammability aspects and the flame spreading to other products are not covered by this document. 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.

IEC 60695-2-11:2021 est disponible sous forme de IEC 60695-2-11:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 60695-2-11:2021 spécifie une méthode d’essai applicable au produit fini. Elle est destinée à simuler les effets des contraintes thermiques produites par une source chauffée électriquement afin de représenter un danger d’incendie. La présente méthode d’essai permet de vérifier que, dans des conditions d’essai définies, un produit fini exposé à une source chauffée électriquement présente une aptitude limitée à s’enflammer ou, s’il s’enflamme, une aptitude limitée à propager la flamme. Cependant, le présent document ne traite pas de l’analyse du danger d'incendie, des aspects d’inflammabilité et de propagation de flammes à d’autres produits. 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 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 nombreux termes et définitions applicables au présent document.

Preskušanje požarne ogroženosti - 2-11. del: Preskusne metode z žarilno žico - Preskušanje vnetljivosti končnega proizvoda z žarilno žico (GWEPT) (IEC 60695-2-11:2021)

Ta del standarda IEC 60695 določa preskusno metodo za končni proizvod. Namenjena je poustvarjanju učinkov toplotne preobremenitve, ki jo proizvede električno ogrevani vir, s čimer se ponazori požarna ogroženost. Ta preskusna metoda se uporablja za preverjanje, ali ima pod opredeljenimi preskusnimi pogoji končni proizvod, ki je izpostavljen električno ogrevanem viru, omejeno sposobnost vžiga ali, če se vžge, omejeno sposobnost širjenja plamena. Vendar pa v tem dokumentu niso zajeti analiza požarne ogroženosti, vidiki vnetljivosti in širjenje plamena na druge proizvode. 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
