Scope

This part of IEC 60079 contains the specific requirements for the design of electrical systems, selection, installation and the required initial inspection of electrical installations of Ex Equipment in, or associated with, explosive atmospheres in underground mines including requirements for documentation and personnel competency.

These requirements are in addition to the requirements for installations in non-hazardous areas.

Purpose

Current standard for electrical installations in explosive atmospheres, IEC 60079-14, excludes electrical installations in mines susceptible to firedamp. Communication with relevant stakeholders and other interested parties identified the need to develop International Standard to fill this gap.
