BS ISO 21448:2022 PDF Download

BS ISO 21448:2022 is an international standard that addresses potential hazards arising from the limitations or intended functionality of electronic and electrical systems in vehicles. It focuses on the concept of safety of the intended functionality (SOTIF), which is different from functional safety in the case of system failures. The standard provides guidance on design, verification, and validation measures required to achieve SOTIF.

The standard is intended for various stakeholders in the automotive industry, including vehicle manufacturers, tier one and tier two suppliers of electrical and electronic devices, software developers, safety consultants, certification agencies, regulatory bodies, academia, and others. These stakeholders play a vital role in ensuring the safety of the intended functionality in vehicles.

ISO 21448 covers situations where situational awareness derived from complex sensors and processing algorithms is critical to safety, such as emergency intervention systems and Advanced Driver Assistance Systems (ADAS) with levels 1 and 2 automation. It can also be considered for higher levels of automation, although additional measures may be necessary.

The use of ISO 21448 can contribute to vehicle homologation and compliance with regulatory requirements. It not only enhances confidence in vehicle safety but also promotes innovation, develops expertise, and strengthens risk management. The standard aligns with UN Sustainable Development Goals, particularly Goal 9 on industry, innovation, and infrastructure, and Goal 11 on sustainable cities and communities.
