    Abstract - (Show below) - (Hide below)

    IEC 60079-0:2017 is also available as IEC 60079-0:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

    IEC 60079-0:2017 specifies the general requirements for construction, testing and marking of Ex Equipment and Ex Components intended for use in explosive atmospheres. The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it may be assumed that Ex Equipment can be operated are:
    -temperature –20 °C to +60 °C;
    -pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and
    -air with normal oxygen content, typically 21 % v/v.
    This part of IEC 60079 and other standards supplementing this standard specify additional test requirements for Ex Equipment operating outside the standard temperature range, but further additional consideration and additional testing may be required for Ex Equipment operating outside the standard atmospheric pressure range and standard oxygen content. Such additional testing may be particularly relevant with respect to Types of Protection that depend on quenching of a flame such as ‘flameproof enclosures “d”’ (IEC 60079-1) or limitation of energy, ‘intrinsic safety “i”’ (IEC 60079-11). This seventh edition cancels and replaces the sixth edition, published in 2011. This edition constitutes a technical revision. Refer to the Foreword of the document for a complete listing of the technical changes between edition 7.0 and the previous edition of the document.
    Keywords: Ex Equipment and Ex Components intended for use in explosive atmospheres
    The contents of the interpretation sheet 1 of April 2019, of the interpretation sheet 2 of June 2019 and the corrigendum 1 of January 2020 have been included in this copy.
