What is IEC 60079-27:2014?

In the field of electrical engineering, safety is of utmost importance. Electrical equipment used in potentially explosive atmospheres poses unique risks and requires careful consideration to ensure the safety of personnel and property. One crucial standard that addresses this issue is the IEC 60079-27:2014.

Purpose and Scope

The IEC 60079-27:2014, formally known as "Explosive atmospheres - Part 27: Equipment protection by fieldbus," provides guidelines for selecting, installing, and maintaining fieldbus devices in hazardous areas. Hazardous environments include locations where flammable gases, vapors, or dust are commonly present, such as chemical plants, oil refineries, or grain processing facilities.

Protecting Against Explosions

Explosions can have catastrophic consequences in industrial settings. The IEC 60079-27:2014 aids in preventing explosions by defining a set of requirements and competencies necessary for the successful implementation of fieldbus technology in these hazardous environments. The document covers both intrinsic safety (IS) and non-incendive (NI) equipment protection methods.

Key aspects addressed in IEC 60079-27:2014 include:

Installation practices: Guidelines for proper installation methods to minimize the risk of ignition.

Defining explosion-proof entities: The standard classifies apparatuses into three distinct levels of protection, namely IA, IB, and IC.

Wiring rules: Specific regulations on safe wiring, including separation and segregation guidelines.

Maintenance considerations: Procedures to ensure ongoing safe operation and identify potential hazards during maintenance activities.

Benefits and Compliance

Adherence to the IEC 60079-27:2014 standard offers several advantages. Firstly, it helps manufacturers design fieldbus equipment that mitigates explosion risks effectively. Secondly, users benefit from a recognized guideline for selecting appropriate fieldbus devices for use in hazardous locations. Compliance with this standard also enhances operational safety and minimizes the potential for accidents or damage to equipment and facilities.

Furthermore, organizations operating in industries where explosive atmospheres are present must meet regulatory requirements. Compliance with the IEC 60079-27:2014 standard ensures conformity with international safety norms and potentially simplifies the certification process.

In conclusion, the IEC 60079-27:2014 provides comprehensive guidance on choosing, installing, and maintaining fieldbus devices in hazardous environments. By following its rules and regulations, industries can enhance the safety of their operations, minimize the risk of explosions, and ensure compliance with international standards.
