What is IEC 60079-36-1:2014 ?

IEC 60079-3:2014 is an essential standard for designing, constructing, and testing electrical equipment in explosive atmospheres. The standard was developed by the International Electrotechnical Commission (IEC) to provide guidelines for the classification of hazardous areas where explosive atmospheres may be present and to minimize the possibility of ignition sources.

Key Requirements of IEC 60079-3:2014

IEC 60079-3:2014 provides various key requirements for the classification of hazardous areas and the design of electrical installations and equipment used in these areas. The standard defines the criteria for classification into different explosive atmospheres, such as Class 0, Class 1, and Class It also provides guidelines for the design and construction of enclosure systems for electrical equipment to prevent explosion.

Explosive atmospheres are defined as areas where the concentration of flammable gases or dusts is greater than 8% by volume. Electrical equipment used in these areas must be designed and constructed to prevent ignition sources, such as arcs, sparks, or continuity. The standard provides guidelines for the selection of materials for enclosure systems, as well as the use of explosion-proofing materials.

In addition to the requirements for enclosure, IEC 60079-3:2014 also provides guidelines for the testing of electrical equipment in explosive atmospheres. The standard specifies the procedures for testing equipment under various explosive atmospheres, including the use of positive and negative pressure.

Conclusion

IEC 60079-3:2014 is an essential standard for the classification and design of electrical equipment used in explosive atmospheres. The standard provides guidelines for the selection of materials for enclosure systems, as well as the use of explosion-proofing materials. By following the guidelines provided in IEC 60079-3:2014, manufacturers can ensure that their electrical equipment is safe and reliable in explosive atmospheres.
