ISO 26262 - Road vehicles — Functional safety

ISO 26262 is an international standard titled:

“Road vehicles — Functional safety”

It is an international standard for functional safety of electrical and/or electronic systems in production automobiles.

The standard is centered around functional safety, aiming to mitigate risks associated with system malfunctions.

Attribute	Relevance in ISO 26262
Safety	The core focus. The standard defines a safety lifecycle and Automotive Safety Integrity Levels (ASILs) to classify risk.
Reliability	Crucial for safety. It requires systematic analysis of failure modes, rates, and effects (e.g., FMEA).
Fault Tolerance	Addressed through requirements for hardware and software architectural design, including redundancy and diagnostic capabilities.
Testability	Mandates comprehensive verification and validation activities throughout the development process.
Traceability	Required to ensure a clear link between requirements, design, implementation, and tests for safety-critical functions.

Note: ISO 26262 is a comprehensive standard that applies to the entire lifecycle of safety-related automotive systems.
