Pre release version
Explosive atmospheres - Part 25: Intrinsically safe electrical systems
IEC 60079-25_2020 (E) contains the specific requirements for design, construction and assessment of intrinsically safe systems, Type of Protection “i”, 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.
NOTE 1 This standard is intended for use by the designer of the system e.g. a person who could be a manufacturer, a specialist consultant or a member of the end-user’s staff.
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.
