What is ISO 21501-4:2017 ?

ISO 21501-4:2017 is a widely recognized standard that outlines the requirements for functional safety in road vehicles. This standard is designed to ensure the safety of vehicles by minimizing the risks associated with the design, development, and production of automobiles. It provides a comprehensive approach to functional safety management throughout the entire product lifecycle, from specification and design to verification and validation.

ISO 21501-4:2017 is made up of several components that work together to achieve functional safety. These components include:

Functional Safety Requirements Specification: This component defines the functional safety requirements for a specific vehicle system or project. It outlines the system's functions, hazards, and safety measures.

Safety Integrity Framework: This component provides a high-level structure for ensuring the integrity of the functional safety management system. It includes guidelines for risk assessment, hazard identification, and safety monitoring.

Safety Plan: This component outlines the plan for achieving functional safety throughout the entire product lifecycle. It includes guidelines for hazard analysis, risk assessment, and safety monitoring.

Safety Case: This component provides a detailed analysis of the risks associated with a specific vehicle system or project. It includes a hazard analysis, risk assessment, and safety monitoring plan.

By following the requirements of ISO 21501-4:2017, automotive manufacturers can ensure that their products meet the necessary safety standards. This standard provides a comprehensive approach to functional safety management, ensuring that the risks associated with vehicle development are minimized and controlled effectively.
