DANSK DSF/PREN IEC 60079-14 PDF

This part of the IEC 60079 series contains the specific requirements for the design of electrical systems, selection, installation and the required initial inspection of electrical installations of Ex Equipment including requirements for documentation and personnel competency in, or associated with, explosive atmospheres. These requirements are in addition to the requirements for installations in non-hazardous areas. NOTE 1 – For voltages up to 1 000 V a.c. or 1 500 V d.c. requirements of this document are based on installation requirements in the IEC 60364 series and for higher voltages in the IEC 61936 series, but other relevant national requirements can apply. For offshore, the IEC 61892 series is applicable. NOTE 2 – Maximum voltages are limited by specific Types of Protection according to other parts of the IEC 60079 series and will be given in the documentation for the Ex Equipment. This document applies to all electrical Ex Equipment including fixed, transportable, portable and personal, and installations, permanent or temporary. NOTE 3 – Guidance on portable electronic equipment can be found in IEC TS 60079-48. This document does not apply to: • electrical installations in mines susceptible to firedamp; NOTE 3 – This document might apply to electrical installations in mines where explosive gas atmospheres other than firedamp can be formed and to electrical installations in the surface installation of mines. • inherently explosive situations and dust from explosives or pyrophoric subs tances (for example explosives manufacturing and processing); • rooms used for medical purposes; • electrical installations in areas where the hazard is due to flammable mist ; and
