This sixth edition cancels and replaces the fifth edition published in 60709-2 Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Manufacturers, designers and specifiers of electrical equipment with pressurized enclosures for use in explosive atmospheres Those who test and maintain such equipment Health and safety bodies Regulatory bodies Why should you use this standard?
For Level of Protection “eb”, this standard applies to electrical equipment where the rated voltage does not exceed 11 kV r. This edition includes the following significant changes, apart from a general review and updating of the first edition of IECharmonization with IEEE Std. Equipment protection by type of protection “n” IEC It is intended that wn should be a stronger link between Part 1 Construction and 600792 2 Performance of this Standard by upgrading the reference in the Scope of part 1 from a note to a requirement.
Please refer to the Foreword of the document for a listing of the changes from the previous edition. Equipment protection by intrinsic safety “”i”” 60079-2 IEC Please refer to the foreword of the document for a detailed listing of the significant technical changes from the previous edition.
Where a requirement of this standard conflicts with a requirement of IECsn requirement of this standard shall take precedence. This has enabled there to be a reduction in the number and length of clauses in the Standard. Overview Product Details What is this standard about? 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.
The faster, easier way to work with standards. Equipment protection by increased safety “e” IEC Refer to the Foreword of the document for a complete listing of the technical changes between edition 660079-2.

The equipment, or parts thereof, is intended for use in explosive atmospheres and in mines susceptible to firedamp. The significant changes with respect to the previous edition should be considered as minor technical revisions.
This first edition cancels and replaces the second edition of IECpublished inand constitutes a full technical revision. 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 6009-2 electrical circuits in the explosive atmosphere may depend upon the design and construction of such electrical equipment or parts of such electrical equipment.

This method of protection has the benefits of Flameproof but does not require a specialised enclosure, generally a standard Industrial enclosure is suitable.
Please refer to the Foreword of the document for the significance of changes between IECEdition 1.
It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. It also covers equipment located outside the explosive atmosphere or protected by a Type of Protection listed in IECbut which generates optical radiation that is intended to enter an explosive atmosphere.

Values of chemical properties of materials are provided to assist in the selection of equipment em be used in hazardous areas. The general revision and updating of Edition 2 of IEC has been necessitated by the advent of new technologies related to caplight design, in particular those related light-emitting diode LED light sources.
This standard is intended to be applied where there can be a risk due to the presence of explosive dust atmospheres or combustible dust layers under normal atmospher ic conditions.
