电气、电子、程序可控的电子安全相关系统的功能性安全.第3部分:软件要求

[中文适用范围]： IEC 61508 系列 a) 的这一部分仅在彻底理解 IEC 61508-1 和 IEC 61508-2 后才能使用； b) 适用于构成安全相关系统一部分或用于开发 IEC 61508-1 和 IEC 61508-2 范围内的安全相关系统的任何软件。此类软件称为安全相关软件（包括操作系统、系统软件、通信网络软件、人机界面功能、固件和应用软件）； c) 提供适用于用于开发和配置 IEC 61508-1 和 IEC 61508-2 范围内的安全相关系统的支持工具的具体要求； d) 要求规定软件安全功能和软件系统能力； e) 建立安全生命周期阶段和活动的要求，这些要求应在安全相关软件（软件安全生命周期模型）的设计和开发过程中应用。这些要求包括措施和技术的应用，这些措施和技术根据所需的系统能力进行分级，以避免和控制软件中的故障和失效； f) 提供与系统安全验证的软件方面相关的信息的要求，以传递给执行 E/E/PE 系统集成的组织； g) 规定了用户操作和维护 E/E/PE 安全相关系统所需的软件信息和程序的准备要求； h) 规定对安全相关软件进行修改的组织应满足的要求； i) 结合IEC 61508-1和IEC 61508-2规定了开发和设计工具、语言翻译器、测试和调试工具、配置管理工具等支持工具的要求； j) 不适用于符合 IEC 60601 系列的医疗设备。 [外文原描述]： Looking for deeper insights? Check out IEC 61508:2010 CMV , which includes commented versions of Parts 1 to 7 of IEC 61508. These commented versions highlight the changes made from previous editions and provide explanations from a world-leading expert on the reasons behind the most significant changes. IEC 61508-3:2010 applies to any software forming part of a safety-related system or used to develop a safety-related system within the scope of IEC 61508-1 and IEC 61508-2; provides specific requirements applicable to support tools used to develop and configure a safety-related system within the scope of IEC 61508-1 and IEC 61508-2; requires that the software safety functions and software systematic capability are specified; establishes requirements for safety lifecycle phases and activities which shall be applied during the design and development of the safety-related software. These requirements include the application of measures and techniques, which are graded against the required systematic capability, for the avoidance of and control of faults and failures in the software; provides requirements for information relating to the software aspects of system safety validation to be passed to the organisation carrying out the E/E/PE system integration; provides requirements for the preparation of information and procedures concerning software needed by the user for the operation and maintenance of the E/E/PE safety-related system; provides requirements to be met by the organisation carrying out modifications to safety-related software; provides, in conjunction with IEC 61508-1 and IEC 61508-2, requirements for support tools such as development and design tools, language translators, testing and debugging tools, configuration management tools. 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. This publication is of high relevance for Smart Grid.
