What is IEC 60079-3:2014

IEC 60079-3:2014 is an international standard that provides guidelines and requirements for the classification and selection of electrical equipment used in hazardous areas, where flammable gases or dust may be present. The standard aims to ensure the safe operation of electrical installations in these environments.

Scope and Objectives

The scope of IEC 60079-3:2014 includes the classification of hazardous areas into zones based on the likelihood of the presence of explosive atmospheres. It also defines the various methods of protection that can be employed to prevent ignition in these areas. The objectives of this standard are to minimize the risk of explosions, protect personnel and property, and provide a framework for manufacturers and users in selecting suitable electrical equipment.

Key Requirements

IEC 60079-3:2014 outlines several key requirements that must be adhered to when selecting electrical equipment for use in hazardous areas:

Electrical Equipment Classification: The standard specifies the criteria for classifying electrical equipment into groups, categories, and temperature classes based on their suitability for different hazardous environments.

Type of Protection: Various types of protection techniques, such as explosion-proof enclosures, intrinsic safety, increased safety, and encapsulation, are detailed in the standard. These techniques help prevent the ignition of explosive atmospheres.

Equipment Marking: The standard includes requirements for equipment marking, including labeling with appropriate symbols and information to indicate their suitability for use in specific hazardous areas.

Testing and Verification: IEC 60079-3:2014 outlines procedures for testing and verification of electrical equipment to ensure compliance with the standard's requirements. These tests typically involve assessing the equipment's resistance to various ignitions sources.

Compliance and Benefits

Adhering to IEC 60079-3:2014 helps manufacturers and users ensure that electrical equipment used in hazardous areas meet internationally recognized safety standards. Compliance with the standard offers several benefits, such as:

Safety: Proper selection and installation of electrical equipment in hazardous areas reduce the risk of explosions and subsequent harm to personnel and property.

Reliability: Electrical equipment that meets the requirements of the standard is more likely to operate reliably in challenging and potentially dangerous environments.

Regulatory Compliance: Following IEC 60079-3:2014 helps organizations comply with relevant regulations and legal requirements related to electrical installations in hazardous areas.

Global Acceptance: The standard is widely recognized and accepted globally, making it easier to trade and sell electrical equipment across different regions and markets.

In conclusion, IEC 60079-3:2014 is an essential international standard that ensures the safe use of electrical equipment in hazardous areas. By following the guidelines and requirements outlined in this standard, manufacturers and users can mitigate the risks associated with explosive atmospheres and protect both personnel and property.
