By IEC TC/SC 31J

This a part of IEC 60079 includes the explicit requisites for the layout, choice and erection of electric installations in explosive gasoline atmospheres. those requisites are as well as the necessities for installations in non-hazardous parts. This commonplace applies to all electric apparatus and installations in detrimental parts no matter if everlasting, transitority, moveable, moveable or handheld. It applies to installations in any respect voltages. This regular doesn't observe to - electric installations in mines at risk of firedamp; - electric installations in components the place the probability is because of flamable dusts or fibres; - inherently explosive events, for instance explosives production and processing; - rooms used for clinical reasons.

3 Matériel destiné à être utilisé en zone 2 Les matériels électriques suivants peuvent être installés en zone 2: a) matériel électrique destiné à être utilisé en zone 0 ou en zone 1, ou b) matériel électrique spécifiquement conçu pour la zone 2 (par exemple, mode de protection «n» conformément à la CEI 60079-15), ou c) matériel électrique conforme aux prescriptions d’une norme reconnue dans le domaine des matériels électriques industriels, qui, en service normal, ne comporte pas de surface chaude susceptible de provoquer une inflammation et qui, 1) en service normal, ne génère pas d’étincelles, ou 2) en service normal, produit des étincelles, mais pour lequel les valeurs, des paramètres électriques (U, I, L et C) du circuit (câbles compris) ne dépassent pas les valeurs spécifiées dans la CEI 60079-11 avec un facteur de sécurité égal à 1.

For TN, TT and IT systems, all exposed and extraneous conductive parts shall be connected to the equipotential bonding system. The bonding system may include protective conductors, metal conduits, metal cable sheaths, steel wire armouring and metallic parts of structures, but shall not include neutral conductors. Connections shall be secure against self-loosening. Exposed conductive parts need not be separately connected to the equipotential bonding system if they are firmly secured to and are in metallic contact with structural parts or piping which are connected to the equipotential bonding system.

NOTE Un document de conformité montre que le matériel a été examiné et, le cas échéant, essayé par un organisme compétent (qui peut être l’utilisateur) et a été trouvé conforme aux exigences de la norme applicable pour le mode de protection particulier. --``,`,`,,,,`,,,,`,```,``````,`-`-`,,`,,`,`,,`--- Copyright International Electrotechnical Commission Provided by IHS under license with IEC No reproduction or networking permitted without license from IHS Licensee=Technip Abu Dabhi/5931917101 Not for Resale, 02/12/2006 05:15:36 MST 60079-14  IEC:2002 – 33 – In addition, the measures to be taken are laid down in writing by persons who – shall be familiar with the requirements for this, and any other relevant standards and code of practice concerning the use of electrical apparatus and systems for use in hazardous areas, – have access to all information necessary to carry out the assessment.
