Annotation of standard text IEC 60695-11-11-ed.1.0 :
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 decrit une methode d’essai utilisee pour determiner la densite de flux de chaleur caracteristique pour l’allumage (CHFI) a partir d’une flamme source sans contact pour les materiaux utilises dans les produits et les sous-ensembles electrotechniques ou leurs composants. Elle donne une relation entre le temps dallumage et la densite de flux de chaleur incident. Une eprouvette d’essai prelevee sur un produit fini ou un sous-ensemble peut etre soumise a l’essai selon la presente methode d’essai. La presente partie de l’IEC 60695 peut etre utilisee dans levaluation des dangers d’incendie et les procedures d’ingenierie de la securite incendie decrites dans l’IEC 60695-1-10, l’IEC 60695 1 11 et l’IEC 60695-1-12. La presente publication fondamentale de securite est destinee a etre utilisee par les comites detudes dans le cadre de lelaboration de normes conformement aux principes etablis dans le Guide IEC 104 et le Guide ISO/IEC 51. Lune des responsabilites dun comite detudes consiste, le cas echeant, a utiliser les publications fondamentales de securite dans le cadre de lelaboration de ses publications. Les exigences, les methodes ou les conditions dessai de la presente publication fondamentale de securite sappliquent seulement si elles sont specifiquement citees en reference ou incluses dans les publications correspondantes. Cette Norme internationale doit etre utilisee conjointement avec l’IEC 60695-11-4. Elle a le statut dune publication fondamentale de securite conformement au Guide IEC 104 et au Guide ISO/IEC 51.
