Annotation of standard text IEC 60079-25-ed.3.1+Amd.1-CSV :

IEC 60079-25:2020+AMD1:2025 CSV contains the specific requirements for design, construction and assessment of intrinsically safe systems, Type of Protection ā€œiā€, intended for use, as a whole or in part, in locations in which the use of Group I, II or III Ex Equipment is required. This document supplements and modifies the general requirements of IEC 60079-0 and the intrinsic safety standard IEC 60079-11. Where a requirement of this standard conflicts with a requirement of IEC 60079-0 or IEC 60079-11, the requirement of this standard takes precedence. The installation requirements of Group II or Group III systems designed in accordance with this standard are specified in IEC 60079-14. This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The contents of the corrigendum 1 of October 2020 and corrigendum 2 of November 2022 have been included in this copy.
