IEC 61508-2:20 10适用于IEC 61508-1定义的任何安全相关系统，该系统至少包含: -一个电气、电子或可编程电子元件； -适用于E/E/PE安全相关系统内的所有元件； -规定如何将根据IEC 61508-1制定的E/E/PE系统安全要求规范细化为E/E/PE系统设计要求规范； -规定了在E/E/PE安全相关系统（软件除外）的设计和制造过程中应用的活动要求，IEC 61508-3中对此进行了处理。 这些要求包括应用以下技术和措施: -根据安全完整性等级进行分级，以避免和控制故障和失效； -规定了执行E/E/PE安全装置的安装、调试和最终安全验证所需的信息-相关系统； -提供用户操作和维护E/E/PE安全相关系统所需的信息和程序的准备要求； -规定对E/E/PE安全相关系统进行任何修改的组织应满足的要求。 这第二版取消并取代了1998年出版的第一版。本版构成技术修订版。它已经过彻底审查，并纳入了在各个修订阶段收到的许多意见。根据IEC指南104，它具有基本安全出版物的地位。 新的！还提供:IEC标准+61508:2010，包含所有零件，以及带注释的红线版本。一位领先的世界专家强调并评论了第二版中的变化。 该出版物与智能电网高度相关。

IEC 61508-2:2010 applies to any safety-related system, as defined by IEC 61508-1, that contains at least:
- one electrical, electronic or programmable electronic element;
- applies to all elements within an E/E/PE safety-related system;
- specifies how to refine the E/E/PE system safety requirements specification, developed in accordance with IEC 61508-1, into the E/E/PE system design requirements specification;
- specifies the requirements for activities that are to be applied during the design and manufacture of the E/E/PE safety-related systems except software, which is dealt with in IEC 61508-3.
These requirements include the application of techniques and measures that:
- are graded against the safety integrity level, for the avoidance of, and control of, faults and failures;
- specifies the information necessary for carrying out the installation, commissioning and final safety validation of the E/E/PE safety-related system;
- provides requirements for the preparation of information and procedures needed by the user for the operation and maintenance of the E/E/PE safety-related systems;
- specifies requirements to be met by the organisation carrying out any modification of the E/E/PE safety-related systems.
This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. It has been subject to a thorough review and incorporates many comments received at the various revision stages. It has the status of a basic safety publication according to IEC Guide 104.

NEW! Also available: IEC Standards+ 61508:2010, containing all parts, together with a commented Redline version. Changes made in this 2nd edition are highlighted and commented by a leading world expert.

This publication is of high relevance for Smart Grid.
