|Publication Date:||1 August 2003|
|ICS Code (Electrical apparatus for explosive atmospheres):||29.260.20|
This part of IEC 60079 contains the specific requirements for construction and assessment of intrinsically safe electrical systems, type of protection "i", intended for use, as a whole or in part, in explosive atmospheres in Group II locations. This standard is intended for use by the designer of the system who may be a manufacturer, a specialist consultant or a member of the end-user's staff.
This standard supplements IEC 60079-11, the requirements of which apply to electrical apparatus used in intrinsically safe electrical systems.
The installation requirements of a Group II system designed in accordance with this standard are specified in IEC 60079-14.
