Anotation

CORRECTED VERSION 2026-05 IEC 60079-11:2023 specifies the construction and testing of intrinsically safe apparatus intended for use in explosive atmospheres, 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 ignition of a surrounding explosive atmosphere. This includes electrical equipment which contains circuits that are intrinsically safe only under certain conditions, for example under battery supply with mains supply removed. This document 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 assessed for use in such atmospheres by applying this document. The contents of the corrigenda 1 (2023-06) and 2 (2026-05) and the interpretation sheets 1 (2024-05), 2 (2024-05), 3 (2024-08), 4 (2025-09) and 5 (2025-09) have been included in this copy. VERSION CORRIGEE 2026-05 IEC 60079-11:2023 specifie la construction et les essais pour le materiel electrique de securite intrinseque destine a etre utilise dans les atmospheres explosives et pour le materiel electrique associe destine a etre relie a des circuits de securite intrinseque qui entrent dans de telles atmospheres. Ce mode de protection s’applique a l’appareil electrique dont les circuits electriques sont eux-memes incapables de provoquer une inflammation dans l’atmosphere explosive environnante. Il inclut l’appareil electrique qui contient des circuits qui sont de securite intrinseque uniquement dans certaines conditions, par exemple alimentes par batterie et alimentation reseau coupee. Le present document s’applique egalement a l’appareil electrique ou aux parties d’appareil electrique situes hors de l’atmosphere explosive ou proteges par un autre mode de protection cite dans l’IEC 60079-0, si la securite intrinseque des circuits electriques situes dans l’atmosphere explosive peut dependre de la conception et de la construction de cet appareil electrique ou de ces parties d’appareil electrique. Les circuits electriques exposes a une atmosphere explosive sont evalues en vue de leur emploi dans de telles atmospheres en appliquant le present document. Les contenus des corrigendas 1 (2023-06) et 2 (2026-05) et des feuilles dinterpretation 1 (2024-05), 2 (2024-05) et 3 (2024-08), 4(2025-09) et 5 (2025-09) sappliquent a la version anglaise uniquement.
