IEC 60079-17:2013 PDF Download

The IEC 60079-17:2013 standard focuses on the inspection and maintenance of electrical installations within hazardous areas where the presence of flammable gases, vapors, mists, dusts, fibers, or flyings can create a potential risk. It specifies the requirements for inspecting and maintaining electrical installations in these explosive atmospheres.

However, it is important to note that this standard does not cover other fundamental installation and inspection requirements for electrical installations, the verification of electrical equipment, or the repair and reclamation of explosion protected equipment. These aspects are addressed in other relevant standards such as IEC 60364-6 and IEC 60079-19.

The standard acknowledges that the level of housekeeping for dusts, fibers, or flyings can influence the inspection and maintenance requirements. It emphasizes that this standard is applicable only to explosive gas or dust mixtures with air or combustible dust layers under normal atmospheric conditions. It does not apply to underground mining areas, dusts of explosives that do not require atmospheric oxygen for combustion, or pyrophoric substances.

The fifth edition of this standard, published in 2013, includes significant technical changes compared to the previous edition. Notably, equipment specific inspection tables for luminaires, heating systems, and motors have been added to Annex A, augmenting the general protection concept tables. Furthermore, the standard has been updated to align with the changes made in the revised edition of IEC 60079-14 for initial inspection.

To fully understand and implement the requirements of this standard, it is recommended to refer to and combine it with the guidance provided in IEC 60364-6:2006.
