Full title and description

Road vehicles — Functional safety — Part 12: Adaptation of ISO 26262 for motorcycles. This part of ISO 26262 provides motorcycle-specific guidance and adaptations to the ISO 26262:2018 functional safety framework for electrical and electronic (E/E) safety-related systems installed in series-production motorcycles (excluding mopeds) and explains tailoring of the safety lifecycle where appropriate for motorcycle applications.

Abstract

ISO 26262-12:2018 defines a framework and requirements to apply the ISO 26262 functional safety lifecycle to motorcycles. It addresses motorcycle-specific topics including safety culture, confirmation measures, hazard analysis and risk assessment, vehicle integration and testing, and safety validation, and explains how to tailor the standard for alterations or integration of existing systems. It does not cover hazards unrelated to E/E malfunction (e.g., fire, toxicity) unless directly caused by E/E system malfunction, and excludes mopeds.

Scope

ISO 26262-12:2018 adapts the ISO 26262:2018 series for application to motorcycles by identifying adaptations, clarifications and additional considerations needed because of motorcycle design, operating context and system integration practices. The document covers adaptation topics across the safety lifecycle — from organizational safety culture and management through hazard analysis and risk assessment, vehicle-level integration and testing, confirmation measures and safety validation, and guidance for tailoring the lifecycle for alterations or integration of legacy systems not originally developed to ISO 26262. It explicitly excludes mopeds and hazards not directly resulting from E/E malfunction.

Key topics and requirements

• Adaptation principles for applying ISO 26262 lifecycle activities to motorcycles (tailoring of requirements and work products).
• Safety culture and organizational capabilities specific to motorcycle development and suppliers.
• Confirmation measures and verification/validation approaches appropriate for motorcycle platforms.
• Hazard analysis and risk assessment considerations for motorcycle dynamics, rider interaction and system interfaces.
• Vehicle integration, system interaction, and vehicle-level testing and validation procedures for motorcycles.
• Guidance on handling alterations to systems already in production and integration of systems developed to different processes.
• Limitations: exclusions for mopeds and non-E/E hazards unless caused by E/E malfunction.

Typical use and users

Primary users are motorcycle OEMs, Tier‑1 and Tier‑2 suppliers of E/E components and systems for motorcycles, safety engineers, systems integrators, test and validation teams, and conformity assessors. The part is used when applying ISO 26262 to motorcycle programs to decide appropriate adaptations of lifecycle activities, to prepare safety cases for motorcycle products, and to align supplier processes with motorcycle-specific safety expectations.

Related standards

ISO 26262-12:2018 is part of the ISO 26262:2018 series (Parts 1–12) and complements other parts such as Part 1 (Vocabulary), Part 2 (Management of functional safety), Part 3 (Concept phase) and Parts 4–6 (product development at system, hardware and software levels). It is also related to broader functional safety standards and guidance like IEC 61508 and to domain guidelines (e.g., industry or regional regulatory documents).

FAQ

Q: What is this standard?

A: ISO 26262-12:2018 is Part 12 of the ISO 26262:2018 series providing adaptations and guidance for applying the automotive functional safety standard specifically to motorcycles.

Q: What does it cover?

A: It covers motorcycle-specific adaptations across the functional safety lifecycle — safety culture, hazard analysis and risk assessment, confirmation measures, vehicle integration and testing, safety validation, and guidance for tailoring the lifecycle for alterations or legacy system integration. It excludes mopeds and non-E/E hazards unless directly caused by E/E malfunction.

Q: Who typically uses it?

A: Motorcycle OEMs, suppliers of motorcycle E/E systems, safety and systems engineers, verification/validation teams, and certification/conformity assessors use this part when developing and validating safety-related motorcycle systems.

Q: Is it current or superseded?

A: ISO 26262-12:2018 was published in December 2018 and remains the published edition; ISO standards are subject to periodic review and the ISO catalogue shows the part listed for review and possible revision activity. Users should verify the current status with their standards provider for any draft revisions or updates.

Q: Is it part of a series?

A: Yes — it is one part (Part 12) of the ISO 26262:2018 series (Parts 1–12) addressing functional safety for road vehicles. Part 12 specifically tailors the series for motorcycles.
