Part 11-11: Test flames – Determination of the characteristic heat flux for ignition from a non-contacting flame source
(IEC 60695-11-11:2021); German version EN IEC 60695-11-11:2021 Class/Status:
VDE Art. No.: 0400548
This document 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 and sub-assemblies. 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 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.
