This standard supplements and modifies the general requirements of IEC except as indicated in Table 1. This seventh edition cancels and replaces the sixth edition, published inand constitutes a technical revision.
You may find similar items within these categories by selecting from the choices below:. Gas detectors – Performance requirements of open path detectors for flammable gases “IEC Caplights for use in mines 6009-2 to firedamp – General requirements – Construction and testing in relation to the risk of explosion “IEC Dealing with general equipment requirements, gas detectors, intrinsically safe equipment, a variety of different methods of equipment protection, and moving on to the classification of areas, material characteristics, and some industry specific standards, the IEC series is truly expansive.
This is Part 2 of the European standard on explosive atmospheres. Refer to the Foreword of the document for a complete listing of the technical changes between edition 2. It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. The principles of this standard can also be followed when combustible fibres or flyings might cause a hazard.
One advantage of purging and pressurising is dn this protection concept also accommodates possible internal releases of flammable gas, vapour or liquid.
Shut-down or alarm in the event of the flow of the protective gas or the overpressure failing. Search all products by. 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.
Caplights for use in mines susceptible to firedamp – Performance and other safety-related matters “IEC The only drawback of Pressurisation is 600079-2 it requires a supply of protective gas, usually 60709-2, to purge the enclosure and keep it pressurised. This publication has the status of a technical report. Equipment protection by liquid immersion “o” IEC The main technical differences with respect to the previious edition are: Applications Electrical equipment whose normal operation involves eb, arcing, or hot components and complex industrial standard equipment controllers whose protection type enables them to be operated in hazardous areas.
The examples in this standard are based on a system of effective housekeeping being implemented in the plant to prevent dust layers from accumulating. Equipment protection by pressurized room “p” and artificially ventilated room “v” IEC Proceed to Checkout Continue Shopping. Additional requirements have been introduced for the protective liquid. Electrical equipment and Ex Components of type of protection increased safety “e” are either: Annexes D and E outline the application of this standard for those users applying the Division method of area classification.
This fifth edition cancels and replaces the fourth edition published inand constitutes a technical revision.
6079-2 This part of IEC applies to electrical equipment where the rated input voltage does not exceed 15 kV r. Please refer to the Foreword of the document for the significance of changes between IECEdition 1. This sixth edition cancels and replaces the first edition of IEC published in Who is this standard for? 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 method of protection has the benefits of Flameproof but does not require a specialised enclosure, generally a standard Industrial enclosure is suitable.

Classification of areas – Explosive gas atmospheres IEC 600792- is intended that there should be a stronger link between Part 1 Construction and Part 2 Performance of this Standard by upgrading the reference in the Scope of part 1 from a note to a requirement.
This has enabled there to be a reduction in the number and length of clauses in the Standard. Level of Protection “eb” applies to equipment or Ex Components, including their connections, conductors, windings, lamps, and batteries; but wn including semiconductors or electrolytic capacitors. Ex Equipment and Ex Components intended for use in explosive atmospheres.

Rooms partially constructed in a manufacturer s facility may include 6009-2 verification. The numerous changes are identified in the Foreword of the document. It is intended to be applied where there may be an ignition hazard due to the presence of flammable gas or vapour, mixed with air, but it does not apply to: This standard supplements and modifies the general requirements of IECexcept as indicated in Table 1 refer to Clause 1 – Scope of the document.
