Full title and description

Road vehicles — Functional safety — Part 10: Guidelines on ISO 26262. An informative guidance document that provides explanations, background and practical guidance to assist understanding and application of the ISO 26262 series for functional safety of electrical/electronic (E/E) systems in road vehicles.

Abstract

This part of ISO 26262 is intended for safety‑related systems that include one or more electrical and/or electronic (E/E) systems installed in series production road vehicles (excluding mopeds). It gives an overview of the ISO 26262 series, explains concepts, offers additional explanatory material, and provides guidance on tailoring the safety lifecycle for existing or integrated systems. The document is informative in character; where inconsistencies occur, the requirements in the other (normative) parts take precedence.

Scope

Provides guidance and explanatory material to help apply the ISO 26262 series to the development, integration and lifecycle of safety‑related E/E systems in road vehicles. It addresses tailoring for systems already in production or under prior development, integration of existing systems not originally developed to ISO 26262, and alterations to existing components. It focuses on hazards caused by malfunctioning behaviour of E/E safety‑related systems and their interactions; it does not cover hazards unrelated to E/E malfunction (e.g., general fire, toxicity) unless directly caused by such malfunctioning behaviour.

Key topics and requirements

• Overview of the ISO 26262 framework and explanation of key concepts (informative guidance).
• Guidance on integrating functional safety activities into company‑specific development lifecycles and on tailoring the safety lifecycle for existing or legacy systems.
• Advice on hazard analysis and risk assessment, ASIL considerations and allocation (context and guidance; normative ASIL requirements are in other parts).
• Recommendations for verification, validation and confirmation measures across the safety lifecycle.
• Supporting processes, organizational capability, competence and evidence needed to demonstrate functional safety.
• Guidance for suppliers, system integrators and for managing interfaces between items and systems.

Typical use and users

Used as explanatory guidance by functional safety engineers, system and software architects, hardware engineers, safety managers, project leads, suppliers and integrators, consultants, and quality or compliance teams working on safety‑related automotive E/E systems.

Related standards

Part of the ISO 26262 series (parts 1–12 in the 2018 edition). Related documents include the normative parts of ISO 26262 (parts 1–9, 11 and 12) and other sector safety standards such as IEC 61508; industry guidance and domain‑specific standards are often used together with ISO 26262 guidance.

FAQ

Q: What is this standard?

A: ISO 26262‑10:2018 is Part 10 of the ISO 26262 series and provides guidelines and explanatory material to help understand and apply the functional safety requirements of the ISO 26262 series for road vehicles.

Q: What does it cover?

A: It covers explanatory guidance, recommended practices for integrating functional safety into development lifecycles, tailoring for existing systems, and interpretive material to clarify the other parts of ISO 26262. It is informative (non‑normative).

Q: Who typically uses it?

A: Functional safety engineers, system and software architects, hardware designers, safety managers, suppliers/integrators, project managers, consultants and compliance/quality teams in the automotive sector.

Q: Is it current or superseded?

A: ISO 26262‑10:2018 is the second edition, published in December 2018; it replaced the 2012 edition (which was withdrawn). The ISO maintenance process reviews standards periodically (typically every five years), so users should check for any revisions or work items if they require the absolute latest status for compliance or procurement.

Q: Is it part of a series?

A: Yes — Part 10 is one part of the ISO 26262 series (“Road vehicles — Functional safety”), which in the 2018 edition comprises parts 1 through 12 (with parts 10 and 11 being guidance documents).

Q: What are the key keywords?

A: Functional safety, automotive, guideline, E/E systems, safety lifecycle, ASIL, hazard analysis, verification, validation, tailoring.
