Electrical apparatus for explosive gas atmospheres. Back to Explosive Atmosphere Standards Home. Gas detectors – Performance requirements of detectors for flammable gases. This standard does not cover ignition by ultraviolet radiation and by absorption of the radiation in the explosive mixture itself. Where a requirement of this standard conflicts with a requirement of IEC , the requirements of this standard take precedence. This standard does not apply to dusts of explosives, which do not require atmospheric oxygen for combustion, or to pyrophoric substances. Artificial ventilation for the protection of analyser s houses Gives the general principles of protection by artificial ventilation.

IS/IEC 60079-1: Explosive Atmospheres, Part 1: Equipment Protection by Flameproof Enclosures ‘d’
This fourth edition cancels and replaces the third edition, published inand constitutes a technical revision. Electrical apparatus protected by enclosures and surface temperature limitation – Specification for apparatus. This edition constitutes a technical revision.
It also includes the requirements for pressurized enclosures containing a limited release of a flammable substance. Electrical apparatus for use in the presence of combustible dust Part 0: These Standards are dedicated to the highly specialised iec 60079-1 associated with the use of equipment, termed Ex equipment, and installations in areas where a potential may exist of fire or explosion. This document deals jec rooms that are partially constructed in a manufacturer s facility and intended to have the final installation completed on-site, as well as rooms that are constructed completely on-site.
Contains specific requirements for the construction and testing 60079–1 electrical apparatus with the type of protection flameproof enclosure ‘d’, intended for use in explosive gas atmospheres.
This sixth edition constitutes a technical revision. Where effective housekeeping is not iec 60079-1, the area classification includes the possible iec 60079-1 of explosive dust clouds from dust layers. Flame arresters – Performance requirements, test methods and limits for use.
Performance and other safety-related matters – Caplights for use in mines susceptible to firedamp.
IEC Series Explosive Atmosphere Standards
Please refer to the foreword of the document for a detailed listing of the significant technical changes from the previous edition. This type of protection is applicable to iex equipment iec 60079-1 which the electrical circuits themselves are incapable of causing an explosion in the surrounding explosive atmospheres. Discover how to find in thousands configurations, the Combination unit for you.
Equipment protection by increased safety “e” IEC This edition ief significant technical changes with regard to the previous edition. 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.

The principles of this standard can also be followed when combustible fibres or flyings might cause a hazard. Equipment protection by liquid immersion “o” IEC This standard supplements and modifies the general requirements of IEC and the intrinsic safety standard IEC In Clause 7 other general considerations for dust layers are described. Protection by intrinsic safety ‘iD’ IEC Electrical apparatus for use in the presence of combustible dust Part Gas detectors – Selection, installation, use and maintenance of detectors for 6009-1 gases and oxygen NEW!
Kec sixth edition cancels and iec 60079-1 the first edition of IEC published in General requirements IEC Electrical apparatus for use in the presence of combustible dust Part 1: This standard does not cover ignition by ultraviolet radiation and by absorption of the radiation in the explosive mixture itself.
Equipment protection by pressurized room “p” and artificially ventilated room “v”. This edition includes the following significant changes, apart from the general revision and updating of the first edition of IEC and harmonization with IEEE Iec 60079-1.
Equipment protection by flameproof enclosures “d” IEC The requirements for performance are in IEC This standard applies to electrical equipment, parts of electrical equipment and Ex components with: For Level of Protection “ec”, this standard applies to electrical equipment where the rated voltage does not exceed 15 kV r.
