What is ISO 26262?

ISO 26262 is an international standard for functional safety in the automotive industry. The standard applies to electrical and electronic systems consisting of hardware and software components in vehicles. ISO 26262 defines requirements to be met by the safety relevant function of the system as well as by processes, methods and tools which are used within the development process. The ISO 26262 standard ensures that sufficient levels of safety are being met and maintained throughout the vehicle lifecycle.

Why is ISO 26262 automotive industry safety standard important?

Using ISO 26262 to evaluate the safety of your vehicle’s electrical and electronic components provides multiple benefits to automotive original equipment manufacturers (OEMs) and suppliers:

  • Demonstrate due diligence and ensure overall safety of the respective vehicle and/or the corresponding systems in compliance with ISO 26262
  • Maintain your competitive advantage in interpreting and implementing the ISO 26262 requirements correctly
  • Minimise the risk of harm to people and non-acceptance of your products by the market
