[中文适用范围]： IEC 61000 的这一部分建立了一种仅针对在操作条件下安装和使用的电气和电子系统及装置的电磁现象实现功能安全的方法。该方法包括其对此类系统和装置中使用的设备的影响。本技术规范： a) 适用于包含电气/电子/可编程电子设备的安全相关系统； b) 考虑电磁环境对安全相关系统的影响；它适用于安全相关系统的设计者、制造商和安装者，并可作为 IEC 委员会的指南； c) 不涉及电磁场对生物的直接危害，也不涉及与绝缘击穿或导致人员暴露于电气危险的其他机制相关的安全。它主要涵盖安全相关系统和其中使用的设备的设计阶段的 EMC 相关方面，并特别涉及 - 功能安全领域的一些基本概念， - 用于实现和管理功能安全的各种 EMC 具体步骤, - 电磁环境的描述和评估， - 设计和集成过程的 EMC 方面，考虑系统和设备级别的 EMC 安全规划过程， - 有关电磁抗扰度的验证和验证过程- 安全相关系统和其中使用的设备的性能标准和一些测试原理考虑因素， - 与安全相关系统和其中使用的设备抗电磁干扰测试有关的方面。本技术规范适用于旨在符合 IEC 61508 和/或相关部门特定功能安全标准要求的安全相关系统。对于其他功能安全标准涵盖的安全相关系统，应考虑本技术规范的要求，以确定应采取的与 EMC 和功能安全相关的适当措施。本技术规范还可用作考虑对安全有直接贡献的其他系统的 EMC 要求的指南。 [外文原描述]： IEC/TS 61000-1-2:2008(E) establishes a methodology for the achievement of functional safety only with regard to electromagnetic phenomena of electrical and electronic systems and installations, as installed and used under operational conditions. This methodology includes the implication it has on equipment used in such systems and installations. IEC/TS 61000-1-2:2008: a) applies to safety-related systems incorporating electrical/electronic/programmable electronic equipment; b) considers the influence of the electromagnetic environment on safety-related systems; it is intended for designers, manufacturers and installers of safety-related systems and can be used as a guide by IEC committees; c) is not concerned with direct hazards from electromagnetic fields on living beings nor is it concerned with safety related to breakdown of insulation or other mechanisms by which persons can be exposed to electrical hazards. IEC/TS 61000-1-2:2008 mainly covers EMC related aspects of the design phase of safety-related systems and equipment used therein, and deals in particular with - some basic concepts in the area of functional safety, - the various EMC specific steps for the achievement and management of functional safety, - the description and assessment of the electromagnetic environment, - the EMC aspects of the design and integration process taking into account the process of EMC safety planning on system as well as on equipment level, - the validation and verification processes regarding the immunity against electromagnetic disturbances, - the performance criterion and some test philosophy considerations for safety-related systems and the equipment used therein, - aspects related to testing of the immunity of safety-related systems and equipment used therein against electromagnetic disturbances. IEC/TS 61000-1-2:2008 is applicable to safety-related systems intended to comply with the requirements of IEC 61508 and/or associated sector-specific functional safety standards. For safety-related systems covered by other functional safety standards, a consideration shall be made of the requirements of this Technical Specification in order to identify the appropriate measures that shall be taken with relation to EMC and functional safety. IEC/TS 61000-1-2:2008 may also be used as a guide for considering EMC requirements for other systems having a direct contribution to safety. IEC/TS 61000-1-2:2008 has the status of a basic safety publication in accordance with IEC Guide 104. This second edition cancels and replaces the first edition published in 2001 and constitutes a technical revision. The main changes are the following: - For safety-related systems that use electrical, electronic or programmable electronic technologies, the technical information, definitions, terminology and text of this second edition have been aligned to IEC 61508. - Risk assessment requirements and methodologies have been deleted from this document, so as not to duplicate or clash with IEC 61508. - It now makes a clear distinction between complete safety-related systems and items of equipment that might be used in such systems, and clarifies its application by the different types of end-users. - It focuses more on appropriate design methods, and their verification and validation. - The methodology for assessing and specifying electromagnetic environments has been extended. - The combination of electromagnetic and physical/climatic influences are taken into account.
