EVS-EN IEC 60079-17:2024

IEC 60079-17 applies to users and covers only those factors directly related to the inspection and maintenance of electrical installations specifically designed for hazardous areas, where the hazard is caused by explosive atmospheres.

It does not include:

— other fundamental installation and inspection requirements for electrical installations;
— the verification of electrical equipment;
— protection or ventilation of rooms;
— gas detection systems;
— the repair, overhaul and reclamation of explosion protected equipment (see IEC 60079-19).

While IEC 60079-17 does not include inspection of safety devices such as used in ventilated rooms (see IEC 60079-13), it does include the requirements for inspection and maintenance of individual items of equipment that will be part of such systems, for example motors or sensors. This standard supplements the requirements for inspection and testing in non-hazardous areas in IEC 60364-6. It is intended to be applied where there is a risk due to the potential presence of explosive gas or dust mixtures with air or combustible dust layers under normal atmospheric conditions.

IEC 60079-17:2023 text has been approved in Europe as EN IEC 60079-17:2024 without any changes.
