本文件适用于安全相关系统，包括一个或多个电气和/或电子（E/E）系统，并安装在批量生产的道路车辆上，不包括轻便摩托车。本文件不涉及特殊车辆中的独特E/E系统，例如为残疾驾驶员设计的E/E系统。 注:存在其他专用的应用特定安全标准，可以补充ISO 26262系列标准，反之亦然。 发布用于生产的系统及其组件，或在本文件发布日期之前已在开发中的系统及其组件，不受本版本范围的限制。 本文件通过根据变更调整安全生命周期，解决了在本文件发布之前发布用于生产的现有系统及其组件的变更。本文件通过调整安全生命周期，解决了未根据本文件开发的现有系统与根据本文件开发的系统的集成问题。 本文件阐述了安全相关E/E系统故障行为可能造成的危害，包括这些系统的相互作用。 它不涉及与电击、火灾、烟雾、热、辐射、毒性、易燃性、反应性、腐蚀、能量释放和类似危险有关的危险，除非直接由安全相关的E/E系统的故障行为引起。 本文件描述了功能安全框架，以帮助开发安全相关的E/E系统。该框架旨在将功能安全活动整合到公司特定的开发框架中。 有些要求有明确的技术重点，以便在产品中实现功能安全；另一些涉及开发过程，因此可以被视为过程要求，以证明组织在功能安全方面的能力。 本文件不涉及E/E系统的标称性能。 本文件规定了汽车应用概念阶段的要求，包括: -项目定义； -危害分析和风险评估；和 -功能安全概念。 附件A概述了本文件的目标、先决条件和工作成果。

This document is intended to be applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production road vehicles, excluding mopeds. This document does not address unique E/E systems in special vehicles such as E/E systems designed for drivers with disabilities. NOTE Other dedicated application-specific safety standards exist and can complement the ISO 26262 series of standards or vice versa. Systems and their components released for production, or systems and their components already under development prior to the publication date of this document, are exempted from the scope of this edition. This document addresses alterations to existing systems and their components released for production prior to the publication of this document by tailoring the safety lifecycle depending on the alteration. This document addresses integration of existing systems not developed according to this document and systems developed according to this document by tailoring the safety lifecycle. This document addresses possible hazards caused by malfunctioning behaviour of safety-related E/E systems, including interaction of these systems. It does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy and similar hazards, unless directly caused by malfunctioning behaviour of safety-related E/E systems. This document describes a framework for functional safety to assist the development of safety-related E/E systems. This framework is intended to be used to integrate functional safety activities into a company-specific development framework. Some requirements have a clear technical focus to implement functional safety into a product; others address the development process and can therefore be seen as process requirements in order to demonstrate the capability of an organization with respect to functional safety. This document does not address the nominal performance of E/E systems. This document specifies the requirements for the concept phase for automotive applications, including the following: — item definition; — hazard analysis and risk assessment; and — functional safety concept. Annex A provides an overview on objectives, prerequisites and work products of this document.
