着火危险试验.第11-5部分:针状火焰试验方法.装置、证实试验协议和指南

[中文适用范围]： IEC 60695的本部分规定了针焰测试，以模拟故障情况下可能产生的小火焰的影响，以便通过模拟技术评估火灾危险。该测试的结果可用作火灾危险评估的要素，该评估考虑了与特定最终用途的火灾危险评估相关的所有因素。它适用于电工设备、其子组件和部件以及固体电绝缘材料或其他可燃材料。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 中规定的原则制定标准。技术委员会的职责之一是，在适用的情况下，使用其出版物的编写过程中涉及基本安全出版物。除非相关出版物中特别提及或包含，否则本基本安全出版物的要求、测试方法或测试条件将不适用。 [外文原描述]： IEC 60695-11-5:2016 specifies a needle-flame test to simulate the effect of a small flame which may result from fault conditions, in order to assess the fire hazard by a simulation technique. The results of this test may be used as elements of a fire hazard assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. It is applicable to electrotechnical equipment, its sub-assemblies and components and to solid electrical insulating materials or other combustible materials. This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - The scope has been broadened to allow this test method to also simulate the effects of small flames from outside the equipment; - Propane and butane gas are the specified fuel source with a minimum purity of 95 %; - A new concept has been added which allows the burner to be moved during the test to avoid dripping material from falling onto the tip of the burner tube; - The burner tube material is now a referenced source; - The reference for the copper block material has changed - the ISO publication (ISO 1337) has been withdrawn with no replacement. A new callout is now used and Informative Annex C and a bibliography have been added. 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.
