IEC 60695-1-21:20 16提供了用于确定电工产品或其形成材料的可燃性的测试方法的总结。它还包括测试方法，其中通过设计，可燃性是一个重要的可量化特征。它代表了测试方法的当前技术水平，并且在可用的情况下，包括对其相关性和使用的特殊观察。测试方法列表不应被视为详尽无遗，除非特别说明，否则不是由IEC开发的测试方法不应被视为由IEC认可。本基本安全出版物主要供技术委员会根据IEC指南104和ISO/IEC指南51中规定的原则编写标准时使用。它不适合制造商或认证机构使用。IEC 60695-1-21的第一版取消并取代了2008年发布的IEC TR 60695-1-21的第一版。它构成技术修订。 与上一版相比，此版本包括以下重大技术变更: -从TR改为国际标准； -修改的介绍； -修改范围； -更新规范性参考文献； -更新术语和定义； -第4条的更新和新案文； -增加关于ASTM D 3638的文本； -附录A的更新和参考书目的更新。 关键词:火灾危险性、消防安全工程、可燃性。

IEC 60695-1-21:2016 provides a summary of test methods that are used to determine the ignitability of electrotechnical products or materials from which they are formed. It also includes test methods in which, by design, ignitability is a significant quantifiable characteristic. It represents the current state of the art of the test methods and, where available, includes special observations on their relevance and use. The list of test methods is not to be considered exhaustive, and test methods which were not developed by the IEC are not to be considered as endorsed by the IEC unless this is specifically stated. This basic safety publication is primarily 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. It is not intended for use by manufacturers or certification bodies. This first edition of IEC 60695-1-21 cancels and replaces the first edition of IEC TR 60695-1-21 published in 2008. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Change from a TR to an international standard;
- Modified Introduction;
- Modified Scope;
- Updated normative references;
- Updated terms and definitions;
- Updates and new text in Clause 4;
- Addition of text concerning ASTM D 3638;
- Updates to Annex A and Updates to the bibliography. Key words: Fire Hazard, Fire Safety Engineering, Ignitability.
