Scope

This document specifies the requirements for vehicles at the conceptual stage, including: --- Definition of related items; --- Hazard analysis and risk assessment; --- Functional safety concept. This document applies to safety-related systems incorporating one or more electrical/electronic systems installed on mass-produced road vehicles other than mopeds. This document does not apply to specific electrical/electronic systems on special purpose vehicles, for example, vehicle systems designed for disabled drivers. Note: Other dedicated safety standards can be used as a supplement to this document, and vice versa. Systems and their components that have been released for production, or that are in development as of the publication date of this document, do not apply to this document. When changes are made to the system and its components that have completed production release before the release of this document, this document tailors the activities of the safety life cycle based on these changes. When a system not developed in accordance with this document is integrated with a system developed in accordance with this document, the safety life cycle needs to be tailored according to this document. This document addresses possible hazards caused by abnormal performance of safety-related electrical/electronic systems, including possible hazards caused by the interaction of these systems. This document does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, energy release, etc. and similar hazards, unless the hazard is directly caused by a safety-related electrical/electronic system caused by the abnormal performance of the function. This document presents a framework for the functional safety development of safety-related electrical/electronic systems, which aims to integrate functional safety activities into an enterprise-specific development framework. This document specifies the technical development requirements to achieve product functional safety, and also specifies the development process requirements for the organization to have corresponding functional safety capabilities. This document does not address the nominal performance of electrical/electronic systems. Appendix A outlines the objectives, prerequisites and work products of this document.
