火灾测试. 第11-11部分: 试验火焰. 从非接触火源点燃的特性热流量的测量

[中文适用范围]： IEC 60695 的这一部分描述了一种测试方法，用于确定电工产品、子组件或其零件中使用的材料的非接触式火焰源的点火特性热通量 (CHFI)。它提供了点火时间和点火时间之间的关系 [外文原描述]： 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.
