Fire hazard testing - Part 1-11: Guidance for assessing the fire hazard of electrotechnical products - Fire hazard assessment
IEC 60695-1-11:2010 provides guidance for assessing the fire hazard of electrotechnical products and for the resulting development of fire hazard testing as related directly to harm to people, animals or property. For the purposes of this standard, product means complete electrotechnical equipments, their parts (including components) and electrical insulating materials. It outlines a hazard-based process to identify appropriate fire test methods and performance criteria for products. The principles of the methodology are to identify fire events (fire scenarios) which will be associated with the product, to establish how the measurable fire properties of the product are related to the possible occurrence and outcome of those events, and to establish test methods and performance requirements for those properties which will either result in a tolerable fire outcome or eliminate the event altogether. This document has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. This publication is to be read in conjunction with IEC 60695-1-10:2009.

Essais relatifs aux risques du feu - Partie 1-11: Lignes directrices pour l'évaluation des risques du feu des produits électrotechniques - Evaluation des risques du feu
La CEI 60695-1-11:2010 fournit des lignes directrices pour évaluer les risques du feu des produits électrotechniques et pour développer, en conséquence, les essais relatifs aux risques du feu liés directement aux dommages aux personnes, aux animaux ou aux biens. Pour les besoins de la présente norme, le terme "produit" signifie des équipements électrotechniques complets, leurs éléments (incluant les composants) et des matériaux électriquement isolants. Elle expose un processus de risques pour identifier les méthodes d'essai au feu appropriées et les critères de performance des produits. Les principes de la méthodologie identifient les événements liés au feu (scénarios feu) qui seront associés au produit, pour établir la façon dont les propriétés mesurables du produit sont liées à la possible survenance et à l'issue de ces événements et pour établir les méthodes d'essai et les exigences de performance pour ces propriétés qui soit donneront lieu à une issue du feu tolérable soit élimineront totalement l'événement. Ce document a le statut de publication fondamentale de sécurité, conformément au Guide CEI 104 et au Guide ISO/CEI 51. Cette publication doit être lue conjointement avec la CEI 60695-1-10:2009.
Preskušanje požarne ogroženosti - 1-11. del: Vodilo za ocenjevanje požarne varnosti elektrotehniških izdelkov - Ocena požarne varnosti (IEC 60695-1-11:2010)
Ta del IEC 60695-1 podaja vodilo za ocenjevanje požarne varnosti elektrotehniških izdelkov in za posledični razvoj preskusov požarne varnosti, ki je neposredno povezana s poškodbami ljudi, živali ali premoženja. Za namene tega standarda izdelek pomeni kompletno elektrotehniško opremo, njene dele (vključno s sestavnimi deli) in električne izolacijske materiale. Podaja postopek, ki temelji na oceni tveganja, za identifikacijo primernih metod preskušanja požarne varnosti in meril učinkovitosti za izdelke. Načela metodologije so identifikacija požarnih dogodkov (predviden potek požara), ki bodo povezani z izdelkom, da bi ugotovili, kako so merljive požarne lastnosti izdelka povezane z morebitnim pojavom in posledico takšnih dogodkov, in da bi vzpostavili preskusne metode in zahteve glede učinkovitosti za tiste lastnosti, ki bodo bodisi imele za posledico sprejemljive posledice požara bodisi bodo popolnoma preprečile dogodek. Ta standard je namenjen kot vodilo odborom IEC ter ga je treba uporabljati z upoštevanjem posamičnih načinov uporabe. Dejanska uporaba tega standarda ostaja odgovornost vsakega odbora za proizvod glede na najmanjšo sprejemljivo požarno varnost na njegovem področju uporabe in z upoštevanjem povratnih informacij na podlagi izkušenj. Ta osnovna varnostna publikacija je namenjena uporabi s strani tehničnih odborov pri pripravi standardov v skladu z načeli, opredeljenimi v IEC Guide 104 in ISO/IEC Guide 51. Ena od odgovornosti tehničnega odbora je, če je primerno, uporabiti temeljne varnostne publikacije pri pripravi svojih publikacij. Zahteve, preskusne metode ali preskusni pogoji te temeljne varnostne publikacije se ne uporabljajo, razen če se ustrezne publikacije nanje izrecno sklicujejo ali jih vključujejo.

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 committe
