爆炸性环境.第11部分:本质安全“i”设备保护

[中文适用范围]： 本部分规定了本质安全型电气设备（包括关联设备和简单设备）的设计、制造和测试要求，旨在防止在潜在爆炸性气体、粉尘或烟雾环境中因电火花或热效应引发爆炸。本标准适用于在特定危险区域使用的电气设备，涵盖从低压电路到变压器、电池及半导体组件等所有相关组件的安全要求。 [外文原描述]： 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.
