The electrical circuits exposed to the explosive atmosphere are evaluated for use in such an atmosphere by applying this standard. Equipment protection by special protection ‘s’ IEC Type testing, Protected electrical equipment, Leak tests, Safety devices, Electrical equipment, Explosive atmospheres, Pressure testing, Electrical safety, Type p protected electrical equipment, Performance testing, Electric enclosures, Design.

Where a requirement of this standard conflicts with a requirement of IECthe requirement of this standard will take precedence. The supply of purging and pressurising air is 6007-92 by a rn control unit.

Equipment protection by flameproof enclosures “d” IEC Large machines, slip ring or collector motors, switchgear and control gear cabinets, and analysis devices. Gas detectors – Selection, installation, use and maintenance of detectors for flammable gases and oxygen NEW!

The application of electrical equipment in atmospheres, which may contain explosive gas as well as combustible dust simultaneously, may require additional protective measures. This sixth edition cancels and replaces the first edition of IEC published in 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.

This document also describes a test method intended for 600079-2 in the determination of the auto-ignition temperature AIT of a vapour-air mixture or gas-air mixture at atmospheric pressure, so as to permit the selection of an appropriate temperature class 06079-2 equipment. The International Electrotechnical Commission IEC series of explosive atmosphere standards covers a wide array of important considerations when it comes to potentially explosive atmospheres.

It also includes a room located in a non-hazardous area that has an internal source of release of a flammable gas or vapour. You may experience issues viewing this site in Internet Explorer 9, 10 or 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.

For Level of Protection “eb”, this standard applies to electrical equipment where the rated voltage does not exceed 11 kV r. This first edition cancels and replaces the second edition of IECpublished inand constitutes a full technical revision.

This fifth edition cancels and replaces the fourth edition published inand constitutes a technical revision. Ex Equipment and Ex Components intended for use in explosive atmospheres.

IEC Series Explosive Atmosphere Standards

One advantage of purging and pressurising is that this protection concept also accommodates possible internal releases of flammable gas, vapour or liquid. Click to learn more. Where a requirement of this standard conflicts with a requirement of IEC or IEC 600079-2, the requirement of this standard takes precedence. This standard does not apply to dusts of explosives, which do not require atmospheric oxygen wn combustion, or to pyrophoric substances. This method eh protection has the benefits of Flameproof but does not require a specialised enclosure, generally a standard Industrial enclosure is suitable.

This fifth edition cancels and replaces the fourth edition, published inand constitutes a technical revision. This standard is also available to be included in Standards Subscriptions.

This type of protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing an explosion in the surrounding explosive atmospheres. Ex Equipment and Ex Components with type of protection liquid immersion “o” Available for Subscriptions.

The significant changes with respect to the previous edition should be considered as minor technical revisions. This standard supplements and modifies the general requirements of IECexcept as indicated in Table 1 refer to Clause 1 – Scope of the document. Equipment protection by increased safety “e” IEC The equipment, or parts thereof, is intended for use in explosive atmospheres and in mines susceptible to firedamp.

IEC 60079 Series Explosive Atmosphere Standards

This second edition of IEC cancels and replaces the first edition, published inand constitutes a technical revision. This publication has the status of a technical report. This fourth 660079-2 cancels and replaces the third edition, published inand constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition: Equipment protection by pressurized enclosure “p” Status: 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 60079-22 depend upon the design and construction of such electrical equipment or parts of such electrical equipment.

The only drawback of Pressurisation is that it requires a supply of protective gas, usually air, to purge the enclosure and keep it pressurised.

Additional requirements have been introduced for the protective liquid.
