    Abstract - (Show below) - (Hide below)

    NEW! IEC 60079-26:2014 is available as IEC Standards+ 60079-26:2014 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.


    IEC 60079-26:2014 specifies alternative requirements for construction, test and marking for electrical equipment that provides Equipment Protection Level (EPL) Ga when single standardised Types of Protection (e.g. Ex "ia", Ex "ma", Ex "da") cannot be applied. This standard also applies to equipment mounted across a boundary where different Equipment Protection Levels may be required. This electrical equipment, within the operational parameters specified by the manufacturer, ensures a very high Level of Protection that includes rare malfunctions related to the equipment or two malfunctions occurring independently of each other. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. This third edition cancels and replaces the second edition published in 2006 and constitutes a technical revision. The numerous changes are identified in the Foreword of the document.
