Fire hazard testing - Part 11-11: Test flames - Determination of the characteristic heat flux for ignition from a non-contacting flame source

Edition date: 2021-05-27
In Force
Available languages: Spanish, English, French
Summary: IEC 60695-11-11:2021 describes a test method used to determine the characteristic heat flux for ignition (CHFI) from a non-contacting flame source for materials used in electrotechnical products, sub-assemblies or their parts. It provides a relationship between ignition time and incident heat flux. A test specimen cut from an end-product or sub-assembly can be tested by this test method.
This part of IEC 60695 can be used in the fire hazard assessment and fire safety engineering procedures described in IEC 60695-1-10, IEC 60695-1-11 and IEC 60695-1-12.
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.
One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.
This international standard is to be used in conjunction with IEC 60695-11-4.
It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51.

IEC 60695-11-11:2021 décrit une méthode d’essai utilisée pour déterminer la densité de flux de chaleur caractéristique pour l’allumage (CHFI) à partir d’une flamme source sans contact pour les matériaux utilisés dans les produits et les sous-ensembles électrotechniques ou leurs composants. Elle donne une relation entre le temps d'allumage et la densité de flux de chaleur incident. Une éprouvette d’essai prélevée sur un produit fini ou un sous-ensemble peut être soumise à l’essai selon la présente méthode d’essai.
La présente partie de l’IEC 60695 peut être utilisée dans l'évaluation des dangers d’incendie et les procédures d’ingénierie de la sécurité incendie décrites dans l’IEC 60695-1-10, l’IEC 60695 1 11 et l’IEC 60695-1-12.
La présente publication fondamentale de sécurité est destinée à être utilisée par les comités d'études dans le cadre de l'élaboration de normes 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. Les exigences, les méthodes ou les conditions d'essai de la présente publication fondamentale de sécurité s'appliquent seulement si elles sont spécifiquement citées en référence ou incluses dans les publications correspondantes.
Cette Norme internationale doit être utilisée conjointement avec l’IEC 60695-11-4.
Elle a le statut d'une publication fondamentale de sécurité conformément au Guide IEC 104 et au Guide ISO/IEC 51.
