Automotive Semiconductors and Functional Safety

Which correctly describes the functional safety standard ISO 26262?

  1. AA standard for reducing hazards caused by failures of electrical and electronic systems in series-production road vehicles, adapted for automotive use from IEC 61508
  2. BA standard covering occupant protection in a collision, such as body crash strength and airbag deployment performance
  3. CAn internationally harmonized standard for quality management systems at automotive parts plants, adding automotive-industry-specific requirements to ISO 9001
Show answer and explanation

Answer: A. A standard for reducing hazards caused by failures of electrical and electronic systems in series-production road vehicles, adapted for automotive use from IEC 61508

ISO 26262 is a functional safety standard for reducing to an acceptable level the risk that a vehicle behaves hazardously due to failures of electrical and electronic systems. It adapts IEC 61508, the basic functional safety standard for electrical/electronic/programmable electronic systems, to automotive use and covers the entire lifecycle from concept through development, production and decommissioning. Crash safety concerns body and airbag performance and is addressed by other requirements. The automotive standard for quality management is IATF 16949.
