It describes a test method intended for the measurement of the maximum experimental safe gaps MESG for gas-air mixtures or vapour-air mixtures 600079-2 normal conditions of temperature and pressure 20 C, ,3 kPa e as to permit the selection of an appropriate group of equipment. The supply of purging and pressurising air is managed by a special control unit. As the voice of the U. This third edition cancels and replaces the second edition published in and constitutes a technical revision.
Equipment protection by pressurized enclosure “p” Status: Refer to the Forward of the document for a complete listing of the technical changes between edition 5.
The numerous changes are identified in the Foreword of the document. It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. This has enabled there to be a reduction in the number and length of clauses in the Standard.
The significant technical changes with respect to the previous edition are: The requirements of this standard apply to both Levels of Protection unless otherwise stated. Applications Electrical equipment whose normal operation involves 6009-2, arcing, or hot components and complex industrial standard equipment controllers whose protection type enables them to 6079-2 operated in hazardous areas.
Level of Protection “eb” applies to equipment or Ex Components, including their connections, conductors, windings, lamps, and batteries; but not including semiconductors or electrolytic capacitors. The requirements for enn safe systems are provided in IEC It also includes requirements for pressurized enclosures containing a limited release of a flammable substance.
