Fire hazard testing - Part 2-10: Glowing/hot-wire based test methods - Glow-wire apparatus and common test procedure

This part of IEC 60695 specifies the glow-wire apparatus and common test procedure to simulate the effects of thermal stresses which may be produced by heat sources such as glowing elements or overloaded resistors, for short periods, in order to assess the fire hazard by a simulation technique. The test procedure described in this document is a common test procedure intended for the small-scale tests in which a standardized electrically heated wire is used as a source of ignition. It is a common part of the test procedures applied to end products and to solid electrical insulating materials or other solid combustible materials. A detailed description of each particular test procedure is given in IEC 60695-2-11, IEC 60695-2-12 and IEC 60695-2-13. 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 60695-2-10:2021 est disponible sous forme de IEC 60695-2-10:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60695-2-10:2021 spécifie l’appareillage et la méthode commune d’essai au fil incandescent pour simuler l’effet de contraintes thermiques qui peuvent être produites par des sources de chaleur telles que des éléments incandescents ou des résistances surchargées, sur de courtes durées, afin d’évaluer de façon simulée les dangers d’incendie. La méthode d’essai décrite dans le présent document représente une méthode commune d’essai destinée aux essais à petite échelle qui utilisent un fil normalisé chauffé électriquement comme source d’allumage. Il s’agit d’une partie commune des méthodes d’essai appliquées aux produits finis et aux matériaux isolants électriques solides ou à d'autres matériaux combustibles. Une description détaillée de chaque méthode d’essai particulière est donnée dans l’IEC 60695 2 11, l’IEC 60695 2 12 et l’IEC 60695-2-13. 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 60695-2-11, l’IEC 60695-2-12 et l’IEC 60695-2-13. Cette troisième édition annule et remplace la deuxième édition parue en 2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) De nouveaux termes et définitions concernant les moments et les durées ont été ajoutés à l'Article 3. b) L'ancienne Annexe A relative aux fabricants et fournisseurs d'appareillage a été supprimée. c) L'Annexe A (ancienne Annexe B) relative aux observations sur l'allumage et l’inflammation qui était informative est devenue normative. d) Une nouvelle Annexe C qui donne une représentation des moments et des durées, ainsi que des exemples du comportement des éprouvettes d’essai, et de la manière de les évaluer a été ajoutée.

Preskušanje požarne ogroženosti - 2-10. del: Preskusne metode z žarilno žico - Aparat z žarilno žico in postopek splošnega preskusa (IEC 60695-2-10:2021)

Ta del standarda IEC 60695 opredeljuje aparat z žarilno žico in določa postopek splošnega preskusa za simulacijo učinkov toplotne preobremenitve, ki jih lahko ustvarijo žareči elementi ali preobremenjeni upori, v kratkih časovnih obdobjih, za ocenjevanje požarne ogroženosti s simulacijsko metodo.
Preskusni postopek, opisan v tem dokumentu, je postopek splošnega preskusa, namenjen za manjše preskuse, v katerih se kot vir vžiga uporabi standardizirana električna ogrevana žica.
Običajno se uporablja pri preskusnih postopkih za končne proizvode in za trdne električne izolacijske materiale ali druge trde gorljive materiale.
Podroben opis vseh posameznih preskusnih postopkov je podan v standardih IEC 60695-2-11, IEC 60695-2-12 in IEC 60695-2-13.
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 pa
