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 safetyrelated
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 product development at the hardware level for automotive
applications, including the following:
— general topics for the product development at the hardware level;
— specification of hardware safety requirements;
— hardware design;
— evaluation of the hardware architectural metrics;
— evaluation of safety goal violations due to random hardware failures; and
— hardware integration and verification.
The requirements of this document for hardware elements are applicable to both non-programmable
and programmable elements, such as ASIC, FPGA and PLD. Further guidelines can be found in ISO 26262-
10:2018 and ISO 26262-11:2018.
Annex A provides an overview on objectives, prerequisites and work products of this document.
