标准范围

IEC 60695-11-11:20 21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入射热通量之间的关系。从最终产品或子组件切割的测试样本可以通过该测试方法进行测试。IEC 60695的这一部分可用于IEC 60695-1-10、IEC 60695-1-11和IEC 60695-1-12中描述的火灾危险评估和消防安全工程程序。本基本安全出版物旨在供技术委员会根据IEC指南104和ISO/IEC指南51中规定的原则编制标准时使用。技术委员会的职责之一是在适用的情况下，在编制其出版物时利用基本安全出版物。除非相关出版物中特别提及或包含，否则本基本安全性出版物的要求、试验方法或试验条件将不适用。本国际标准应与IEC 60695-11-4结合使用。根据IEC指南104和ISO/IEC指南51，它具有基本安全出版物的地位。

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.
