标准摘要
[中文适用范围]: IEC 61326-1 的范围适用于 IEC 61326 的这一部分,但仅限于在特定电磁环境下用于工业应用的系统和设备,旨在执行 IEC 61508 中定义的 SIL 1-3 安全功能。本产品系列标准涵盖的电磁环境为工业用电磁环境,包括室内和室外,因为它们存在于具有特定特性的电磁环境的工业应用(例如,过程工业)中。本标准涵盖的电磁环境与一般工业环境(参见 IEC 61326-3-1)之间的差异在于针对导致特定电磁环境的电磁现象所采取的缓解措施。具有特定电磁环境的工业应用环境通常包括以下特征: – 访问受限的工业区; – 移动发射器的使用受限; – 电源和控制、信号或通信线路的专用电缆; – 电源与控制、信号或通信电缆分离; – 厂房主要由金属结构组成; – 通过适当措施采取过压/雷电保护(例如,建筑物采用金属结构或使用保护装置); – 可能存在由交流主电源驱动的管道加热系统; – 敏感区域附近没有高压变电站; – 存在仅使用低功率的 ISM 频率的 CISPR 11 第 2 组 ISM 设备; – 有能力的工作人员; – 设备和系统的定期维护; – 设备和系统的装配和安装指南。 附录 B 给出了上述典型特性的更详细描述。 根据 IEC 61508 或 IEC 61511 被视为“已在使用中证明”的设备和系统不在 IEC 61326-3-2 的范围内。用于保护建筑物的火灾报警系统和安全报警系统不在 IEC 61326-3-2 的范围内。 [外文原描述]: IEC 61326-1 applies to this part of IEC 61326 but is limited to systems and equipment for industrial applications within a specified electromagnetic environment and intended to perform safety functions as defined in IEC 61508 with SIL 1-3. The electromagnetic environments encompassed by this product family standard are industrial, both indoor and outdoor, as they can be found in industrial applications with an electromagnetic environment having specified characteristics (for example, process industry). The difference between the electromagnetic environment covered by this standard compared to the general industrial environment (see IEC 61326-3-1) is due to the mitigation measures employed against electromagnetic phenomena leading to a specified electromagnetic environment. The contents of Interpretation Sheet 1 of June 2013 have been included in this copy.
