(Main)Explosive atmospheres - Part 14: Electrical installations design, selection and erection
Explosive atmospheres - Part 14: Electrical installations design, selection and erection
This part of IEC 60079 contains the specific requirements for the design, selection and erection of electrical installations in hazardous areas associated with explosive atmospheres. Where the equipment is required to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion, additional methods of protection may be necessary. The method used should not adversely affect the integrity of the enclosure. The requirements of this standard apply only to the use of equipment under normal or near normal atmospheric conditions. The significant technical changes with respect to the previous edition are: Equipment Protection Levels (EPLs) have been introduced and are explained in the new Annex I and dust requirements included from IEC 61241 14, Ed. 1.0.
Explosionsfähige Atmosphäre - Teil 14: Projektierung, Auswahl und Errichtung elektrischer Anlagen
Atmosphères explosives - Partie 14: Conception, sélection et construction des installations électriques
La présente partie de la CEI 60079 établit les exigences particulières de conception, de sélection et de montage applicables aux installations électriques situées dans des emplacements dangereux en relation avec des atmosphères explosives. Lorsqu'il est exigé que le matériel soit conforme à d'autres conditions environnementales, par exemple la protection contre la pénétration de l'eau et la résistance à la corrosion, des méthodes complémentaires de protection peuvent être nécessaires. Il convient que la méthode utilisée ne dégrade pas l'intégrité de l'enveloppe. Les exigences de la présente norme s'appliquent uniquement à l'utilisation de matériels dans des conditions atmosphériques normales ou proches de la normale. Les modifications techniques significatives par rapport à l'édition précédente sont les suivantes: Les niveaux de protection de matériel (EPLs pour ' Equipment Protection Levels ') ont été introduits et ils sont expliqués dans une nouvelle Annexe I et les exigences pour les poussières issues de la CEI 61241-14, ed 1.0.

ATEX Categories and Equipment Protection Levels (EPLs) This European Standard has been written to incorporate the concept of Equipment Protection Levels (EPLs). EPLs are analogous to the ATEX Categories, indeed the definitions are identical. Wherever there is a reference to an EPL in the text it should be equated with the corresponding ATEX Category: - EPL ‘Ga’ equates to ATEX Category 1G; - EPL ‘Gb’ equates to ATEX Category 2G; - EPL ‘Gc’ equates to ATEX Category 3G; - EPL ‘Da’ equates to ATEX Category 1D; - EPL ‘Db’ equates to ATEX Category 2D; - EPL ‘Dc’ equates to ATEX Category 3D.
