标准范围

IEC TR 62222:2021描述了与金属和光纤通信电缆防火性能反应相关的各种参数的测试方法。这些参数对于打算安装在建筑物和其他结构内的电缆特别重要。本文件还列出了适用于特定安装条件造成的火灾危险的测试方法和相关限值，可供其他国际、地区和国家标准参考。例如，考虑到本文件，遵守ISO/IEC 14763-2中安装方法的要求和建议可以提高火灾安全性，这一点很重要。这第三版取消并取代了2012年出版的第二版。与上一版相比，此版本包括以下重大技术变更:-重写范围以澄清并纳入其他技术来源的当前理解；-更新规范性参考文献，以符合最新的技术定义和新增内容；-在附件F中增加了新的附加术语和定义，因为这些术语和定义在文件中没有使用；-缩写术语清单中的新内容，一些更正；-项目报告现载于附件E，仅供参考；-关于减轻火灾危险、关于防火的分条款，更新了关于标准的更明确信息，并更新了已公布或修订的新标准；-更新了测试方法、测试方法结论和防火性能。

IEC TR 62222:2021 describes the test methods for various parameters relating to the reaction to fire properties of metallic and optical fibre communications cables. The parameters have particular importance for cables intended to be installed within buildings and other structures. This document also maps the test methods and associated limits applied to the fire hazards created by particular installation conditions and which can be referenced by other international, regional and national standards. For example, it is important that compliance with the requirements and recommendations for installation methods in ISO/IEC 14763-2 taking into consideration this document improve safety concerning fire.
This third edition cancels and replaces the second edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition:
- Scope rewritten to clarify and bring into line current understanding from other technical sources;
- Normative References updated to be in line with the most recent technical definitions and new additions;
- new additional terms and definitions added to Annex F since these are not used in the document;
- new inclusions to the list of abbreviated terms, some corrections;
- project reports are now in Annex E, for information only;
- Subclause about mitigation of fire hazards, about fire protection, updated with clearer information on standards plus updates where new standards have been published or amended;
- test methods, test methods conclusions and fire performance updated.
