新的！IEC 60695-11-5:20 16作为IEC 60695-11-5:20 16 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60695-11-5:20 16规定了针状火焰测试，以模拟故障条件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。这第二版取消并取代了2004年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-扩大了范围，允许该测试方法也模拟来自设备外部的小火焰的影响；-丙烷和丁烷气体是规定的燃料源，最低纯度为95%；-增加了一个新概念，允许燃烧器在测试期间移动，以避免滴落的材料落到燃烧器管的尖端上；-燃烧器管材料现在是参考源；-铜块材料的参考已更改-ISO出版物（ISO 1337）已被撤回，没有替代品。现在使用了新的标注，并增加了信息丰富的附件C和参考书目。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。关键词:火灾危险、试验火焰、针焰试验法

NEW!IEC 60695-11-5:2016 is available as IEC 60695-11-5:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

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- The reference for the copper block material has changed - the ISO publication (ISO 1337) has been withdrawn with no replacement.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.
