(Main)Explosive atmospheres - Part 15: Equipment protection by type of protection "n"
Explosive atmospheres - Part 15: Equipment protection by type of protection "n"
IEC 60079-15:2010 specifies requirements for the construction, testing and marking for Group II electrical equipment with type of protection, 'n' intended for use in explosive gas atmospheres. This standard applies to electrical equipment where the rated voltage does not exceed 15 kV r.m.s. a.c. or d.c. This standard supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. The significant technical changes with respect to the previous edition are as follows: - addition of equipment protection levels; - removal of the requirements for energy-limited 'nL' and associated energy limited apparatus '[nL]'; - removal of the requirements for encapsulated Devices 'nC'; - requirements for electrical connections expanded and clarified; - requirements for electrical connections expanded and clarified; - requirements for luminaire ballasts expanded and clarified; - requirements for evaluation and testing of motor rotors clarified; - 15 kV limit for equipment protection by type of protection 'n' added; - spacing requirement for voltages above 10 kV modified; - requirements for restricted breathing enclosures modified; - modification to requirements for motor rotors and stators; - addition of Annex A (informative); - and undated references to IEC 60079-0 included.

CEI 60079-15:2010 spécifie les exigences de construction, d'essai et de marquage du matériel électrique du Groupe II avec mode de protection ' n ' destiné à être utilisé en atmosphère explosive gazeuse. La présente norme s'applique au matériel électrique dont la tension assignée ne dépasse pas 15 kV efficace, c.a. ou c.c. La présente norme complète et modifie les exigences générales de la CEI 60079-0, à l'exception de celles qui sont indiquées dans le Tableau 1. Si une exigence de la présente norme est en conflit avec une exigence de la CEI 60079-0, l'exigence de la présente norme prévaut. Les modifications techniques importantes par rapport à l'édition précédente sont les suivantes: - ajout des niveaux de protection des matériels; - retrait des exigences pour les appareils ' nL ' à énergie limitée et les appareils ' [nL] ' à énergie limitée associés; - retrait des exigences pour les dispositifs encapsulés ' nC '; - exigences étendues et clarifiées pour les raccordements électriques; - exigences étendues et clarifiées pour les ballasts pour luminaire; - exigences clarifiées pour l'évaluation et les essais sur les rotors de moteur; - limite de 15 kV ajoutée pour la protection du matériel du mode de protection ' n'; - exigence en matière d'espacement modifiée pour les tensions supérieures à 10 kV; - exigences modifiées pour les enveloppes à respiration limitée; - modification des exigences pour les stators et rotors de moteurs; - ajout de l'Annexe A (informative); - introduction de références non datées à la CEI 60079-0.
Eksplozivne atmosfere - 15. del: Zaščita opreme s protieksplozijsko zaščito "n" (IEC 60079-15:2010)
Ta del IEC 60079 določa zahteve za konstrukcijo, preskušanje in označevanje električne opreme skupine II s protieksplozijsko zaščito »n«, namenjene uporabi v eksplozivnih plinskih atmosferah. Ta standard velja za električno opremo, pri kateri nazivna napetost ne presega 15 kVrms dvosmernega ali enosmernega toka.
Ta del IEC 60079 velja za električno opremo, ki se ne iskri, in za električno opremo z deli ali vezji, ki proizvajajo električne obloke ali iskre ali imajo vroče površine, ki bi lahko vžgale obdajajočo eksplozivno plinsko atmosfero, če niso zaščitene na enega od načinov, navedenih v tem standardu. Ta standard opisuje več različnih metod, s katerimi se to lahko doseže, ki se lahko kombinirajo z drugimi metodami, opisanimi v IEC 60079-0.
Ta standard dopolnjuje in spreminja splošne zahteve IEC 60079-0, razen kot je nakazano v preglednici 1. Kjer zahteva tega standarda nasprotuje zahtevi IEC 60079-0, ima zahteva tega standarda prednost.
