Fire hazard testing - Part 1-11: Guidance for assessing the fire hazard of electrotechnical products - Fire hazard assessment

IEC 60695-1-11:2014 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. 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 second edition cancels and replaces the first edition of IEC 60695-1-11 published in 2010, and constitutes a technical revision. The main changes with respect to the previous edition are: - updated references; - updated terms and definitions; - added Figure 5 - Description of range of products and circumstances of use; - and updated Bibliography. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. This standard is to be used in conjunction with IEC 60695-1-10. Key words: Fire Hazard, Fire Test Method, Assessment

Essais relatifs aux risques du feu - Partie 1-11: Lignes directrices pour l'évaluation du danger du feu des produits électrotechniques - Evaluation du danger du feu

L'IEC 60695-1-11:2014 fournit des lignes directrices pour évaluer le danger du feu des produits électrotechniques et pour développer, en conséquence, les essais relatifs au danger du feu liés directement aux dommages aux personnes, aux animaux ou aux biens. Elle expose un processus de danger pour identifier les méthodes d'essai aux feux appropriés 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 relatives 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. Cette deuxième édition annule et remplace la première édition de l'IEC 60695-1-11 publiée en 2010. Elle constitue une révision technique. Par rapport à l'édition précédente, les modifications majeures sont les suivantes: - mise à jour des références; - mise à jour des termes et définitions; - ajout figure 5 - Description de la gamme de produits et des circonstances d'utilisation; - et mise à jour de la Bibliographie. Elle a le statut d'une publication fondamentale de sécurité conformément au Guide IEC 104 et au Guide ISO/IEC 51. Mots-clés: danger du feu, méthode d'essai au feu, évaluation

Preskušanje požarne ogroženosti - 1-11. del: Vodilo za ocenjevanje požarne varnosti elektrotehniških izdelkov - Ocena požarne varnosti

Ta del standarda IEC 60695 podaja navodila za ocenjevanje požarne ogroženosti elektrotehniških izdelkov in za na njem temelječ razvoj preskušanja požarne ogroženosti v povezavi s poškodbami ljudi, živali ali lastnine.
Opredeljuje postopek, ki temelji na požarnih grožnjah, za opredelitev primernih požarnih preskusnih metod in kriterijev delovanja za izdelke. Načela metodologije so opredelitev primerov požarov (požarnih scenarijev), ki so povezani z izdelkom, opredelitev načina za povezavo merljivih požarnih lastnosti izdelka z možnostjo pojava teh scenarijev in njihovih posledic, ter opredelitev preskusnih metod in zahtev delovanja za tiste lastnosti, ki so lahko vzrok za pojav še sprejemljivih požarnih posledic ali ki lahko povsem preprečijo pojav požarnega scenarija.
Standard predstavlja smernice, ki jih odbori IEC lahko uporabljajo za njihove namene. Za dejansko uporabo tega dokumenta so odgovorni odbori vsakega posameznega izdelka ob upoštevanju minimalne sprejemljive stopnje požarne varnosti na področju uporabe izdelka in preteklih povratnih informacij.
Ta osnovna varnostna publikacija je namenjena tehničnim odborom za pripravo standardov v skladu z načeli vodil IEC 104 in ISO/IEC 51 [10].
Ena od odgovornosti tehničnega odbora je, da kjer je to primerno, uporablja osnovne varnostne publikacije. Zahteve, preskusne metode ali preskusni pogoji iz te osnovne varnostne publikacije se ne uporabljajo, razen če so izrecno navedeni ali zajeti v ustrezne publikacije.
