About This Item
TS ISO 26262-1 defines the vocabulary used in road vehicle functional safety and serves as the common terminology base for this technical field. It supports a consistent understanding of safety-related concepts for electrical and/or electronic (E/E) systems, helping engineers, suppliers, and verification teams use the same terms with the same meaning across development and assessment activities.
This part is intended for safety-related systems that include one or more E/E systems installed in series production road vehicles, excluding mopeds. It also does not address unique E/E systems in special vehicles, such as systems designed for drivers with disabilities. These boundaries clarify the vehicle classes and application context for which the vocabulary is intended.
Why a functional safety vocabulary matters
Functional safety is concerned with keeping a system at an acceptable safety level even when faults occur, not only during normal operation. In road vehicles, sensors, controllers, actuators, and software logic often interact closely, so precise terminology is essential for engineering communication, risk analysis, and validation. A vocabulary standard like this helps align interpretation across design, integration, and testing workflows.
