• Electrical apparatus for use in the presence of combustible dust - Part 11: Protection by intrinsic safety "iD"

  Description:

  This part of IEC 61241 specifies requirements for the construction and testing of intrinsically safe apparatus intended for use in potentially explosive dust cloud or dust layer environments and for associated apparatus that is intended for connection to intrinsically safe circuits which enter such environments. This standard supplements the general requirements of IEC 61241-0: except as indicated in the following list. Apparatus utilized in systems will meet the requirements of IEC 60079-25.

  Although the standard’s status is withdrawn, it still has the presumption of conformity in the meaning of directive 94/9/EC and conformance with the directive’s requirements can be guaranteed by using the withdrawn version of the standard. The presumption of conformity is valid until a corresponding amendment is published in the Official Journal of the European Union.
