Explosive atmospheres - Part 11: Equipment protection by intrinsic safety "i"

NEW! IEC 60079-11:2011 is now available as IEC Standards+ 60079-11:2011 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60079-11:2011 specifies the construction and testing of intrinsically safe apparatus intended for use in an explosive atmosphere and for associated apparatus, which is intended for connection to intrinsically safe circuits which enter such atmospheres. This type of protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing an explosion in the surrounding explosive atmospheres. This standard is also applicable to electrical equipment or parts of electrical equipment located outside the explosive atmosphere or protected by another Type of Protection listed in IEC 60079-0, where the intrinsic safety of the electrical circuits in the explosive atmosphere may depend upon the design and construction of such electrical equipment or parts of such electrical equipment. The electrical circuits exposed to the explosive atmosphere are evaluated for use in such an atmosphere by applying this standard. The requirements for intrinsically safe systems are provided in IEC 60079-25. 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 requirements of this standard shall take precedence. This sixth edition cancels and replaces the fifth edition of IEC 60079-11 published in 2006, the first edition of IEC 61241-11 published in 2005, and partially replaces the second edition of IEC 60079-27 published in 2008 and constitutes a full technical revision. The significant changes with respect to the previous edition are listed below: - Inclusion of non-edition specific references to IEC 60079-0. - The merging of the apparatus requirements for FISCO from IEC 60079-27. - The merging of the requirements for combustible dust atmospheres from IEC 61241-11. - Clarification of the requirements for accessories connected to intrinsically safe apparatus; such as chargers and data loggers. - Addition of new test requirements for opto-isolators. - Introduction of Annex H about ignition testing of semiconductor limiting power supply circuits. The contents of the corrigendum of January 2012 have been included in this copy.

Explosionsgefährdete Bereiche - Teil 11: Geräteschutz durch Eigensicherheit "i"

Atmosphères explosives - Partie 11: Protection de l'équipement par sécurité intrinsèque "i"

NEW! La CEI 60079-11:2011 est maintenant disponible sous forme de IEC Standards+ 60079-11:2011 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. La CEI 60079-11:2011 spécifie la construction et les essais pour le matériel électrique de sécurité intrinsèque destiné à être utilisé dans les atmosphères explosives et pour le matériel électrique associé destiné à être relié à des circuits de sécurité intrinsèque qui entrent dans de telles atmosphères. Ce mode de protection s'applique aux équipements électriques dont les circuits sont eux-mêmes incapables de provoquer l'explosion de l'atmosphère environnante. La présente norme s'applique également aux équipements électriques ou aux parties de matériels électriques situés hors de l'atmosphère explosive ou protégés par un autre Mode de Protection cité dans la CEI 60079-0, lorsque la sécurité intrinsèque des circuits électriques situés dans l'atmosphère explosive peut dépendre de la conception et de la construction de ces matériels électriques ou de ces parties de matériels électriques. Les circuits électriques exposés à une atmosphère explosive sont évalués en vue de leur emploi dans une telle atmosphère en appliquant la présente Norme. Les exigences pour les systèmes de sécurité intrinsèque sont données dans la CEI 60079-25. La présente norme complète et modifie les exigences générales de la CEI 60079-0, à l'exception de ce qui est indiqué au Tableau 1. Lorsqu'une exigence de la présente norme entre en conflit avec une exigence de la CEI 60079-0, l'exigence de la présente Norme prévaut. Cette sixième édition annule et remplace la cinquième édition de la CEI 60079-11 publiée en 2006, la première édition de la CEI 61241-11 publiée en 2005, et remplace partiellement la seconde édition de la CEI 60079-27 publiée en 2008 dont elle constitue une révision technique complète. Les modifications importantes par rapport à l'édition antérieure sont indiquées ci-dessous: - Introduction d'une référence à la CEI 60079-0 non spécifique à l'édition; - L'incorporation des exigences de matériel issues de la CEI 60079-27 relatives au FISCO; - L'incorporation des exigences issues de la CEI 61241-11 relatives aux atmosphères de poussières combustibles; - La clarification des exigences relatives aux accessoires reliés à un matériel à sécurité intrinsèque; - tels que les chargeurs et les collecteurs de données; - Ajout de nouvelles exigences d'essai relatives aux isolateurs optiques; - l'introduction d'une Annexe H-au sujet des essais d'inflammation des dispositifs de limitation d'alimentation électrique à semi-conducteur. Le contenu du corrigendum de janvier 2012 a été pris en considération dans cet exemplaire.

Eksplozivne atmosfere - 11. del: Zaščita opreme z lastno varnostjo "i" (IEC 60079-11:2011)

Ta del standarda IEC 60079 določa konstrukcijo in preskušanje lastnovarnih naprav, namenjenih uporabi v eksplozivni atmosferi, in povezanih naprav, namenjenih povezavi z lastnovarnimi tokokrogi, ki vstopajo v take atmosfere. Ta vrsta zaščite se uporablja za električno opremo, v kateri električni tokokrogi sami ne morejo povzročiti eksplozije v okoliških eksplozivnih atmosferah. Ta standard se uporablja tudi za električno opremo ali dele električne opreme, ki je zunaj eksplozivne atmosfere ali jo varuje še ena vrsta zaščite, navedena v standardu IEC 60079-0, pri čemer je lastna varnost električnih tokokrogov v eksplozivni atmosferi lahko odvisna od zasnove in konstrukcije take električne opreme ali delov take električne opreme. Uporaba električnih tokokrogov, izpostavljenih eksplozivni atmosferi, se ovrednoti s tem standardom. Zahteve za lastnovarne sisteme so podane v standardu IEC 60079-25. Ta standard dopolnjuje in spreminja splošne zahteve standarda IEC 60079-0, razen kakor je prikazano v preglednici 1. Kadar je zahteva iz tega standarda v nasprotju z zahtevo iz standarda IEC 60079-0, imajo prednost zahteve iz tega standarda. Če se zahteve iz tega standarda uporabljajo za lastnovarne naprave in povezane naprave, se izraz »naprava« uporablja v celotnem standardu. Ta standard obravnava le električno opremo; zato izraz »oprema«, ki se uporablja v njem, vedno pomeni »električno opremo«. Če v eksplozivno atmosfero postavite povezano napravo, jo je treba zavarovati z ustrezno vrsto zaščite iz standarda IEC 60079-0, zato se zanjo uporabljajo zahteve te metode zaščite in ustrezni deli standarda IEC 60079-0.
