This standard is also applicable to electrical equipment or parts of electrical equipment located outside the explosive atmosphere or protected by another Type of Protection listed in IECwhere the intrinsic safety of the electrical circuits in the explosive atmosphere may depend upon the design and construction of such electrical equipment or parts of such electrical equipment.

The requirements for intrinsically safe systems are provided in IEC Applications Electrical equipment whose normal operation involves sparks, arcing, or hot components and complex industrial standard equipment controllers whose protection type enables them to be operated in hazardous areas. Ex Equipment and Ex Components with type of protection liquid immersion “o” Available for Subscriptions.

Where a requirement of this standard conflicts with a requirement of BS ENthe requirements of this standard take precedence. This standard supplements and modifies the general requirements of BS EN Please refer to the Foreword of the document for a 6007-92 of the changes from the previous edition.

Where effective housekeeping is not present, the area classification includes the possible formation of explosive dust clouds from dust layers. This standard does not include the requirements for: Gives the general principles of protection by artificial ventilation.

The electrical circuits exposed to the explosive atmosphere 600779-2 evaluated for use in such an atmosphere by applying this standard. This second edition cancels and replaces the first edition published in This publication has the status of a technical report. 60079- 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.

Rooms partially constructed in a manufacturer s facility may include third-party verification.
