Fire performance of communication cables installed in buildings

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:
