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 provides an overview of the ISO 26262 series of standards, as well as giving additional explanations, and is intended to enhance the understanding of the other parts of the ISO 26262 series of standards. It has an informative character only and describes the general concepts of the ISO 26262 series of standards in order to facilitate comprehension. The explanation expands from general concepts to specific contents. In the case of inconsistencies between this document and another part of the ISO 26262 series of standards, the requirements, recommendations and information specified in the other part of the ISO 26262 series of standards apply.
Abstract
Overview
ISO 26262-10:2018 - "Road vehicles - Functional safety - Part 10: Guidelines on ISO 26262" is an informative guidance document in the ISO 26262 series. It explains the concepts, terminology and practical application of the functional safety framework for safety-related electrical/electronic (E/E) systems in series-production road vehicles (excluding mopeds and specialised single vehicles). Part 10 is intended to help organizations integrate ISO 26262 activities into company-specific development lifecycles and to improve understanding of the other parts of ISO 26262. It is guidance only; where conflicts exist, normative requirements in other ISO 26262 parts take precedence.
Key topics and technical focus
ISO 26262-10 expands on many core functional-safety subjects and provides practical explanation rather than new normative requirements:
- Functional safety concepts and relationship to IEC 61508
- Item, system and element definitions and their relationships
- Faults → errors → failures progression and timing concepts (FTTI)
- Hazard Analysis and Risk Assessment (HARA) examples and controllability classification
- Safety management, including work products, confirmation measures and functional safety assessment
- Safety cases: interpretation and lifecycle guidance
- System and concept phase guidance for safety goal derivation and external measures
- Hardware guidance: classification of random hardware faults (single-point, dual-point, residual, detected/latent classes), PMHF concepts and quantitative examples
- ASIL decomposition and examples for allocating Automotive Safety Integrity Levels
- Safety Element out of Context (SEooC) development and use-case guidance
- Proven-in-use arguments, safety-related availability and fault-tolerant design
- Software considerations, tool confidence and safety-related special characteristics
- Fault tree construction and practical applications (informative annex)
Practical applications - who uses it
ISO 26262-10 is useful for:
- Automotive OEMs and Tier suppliers implementing ISO 26262 functional safety processes
- Functional safety engineers, system architects and hardware/software developers needing practical interpretation of standard concepts
- Project managers, assessors and safety auditors preparing confirmation measures and safety cases
- Teams planning ASIL decomposition, SEooC integration, or proven-in-use justification
The guidance helps integrate functional safety into product development lifecycles, tailor the safety lifecycle for altered or legacy systems, and clarify how to handle E/E system interactions and availability requirements.

- Cross-reference: IEC 61508 for broader functional safety principles
- Note: Part 10 is informative; when inconsistencies occur, refer to the normative parts of ISO 26262.
