What is ISO/TS 25237:2019?

ISO/TS 25237:2019 is an international standard for the functional safety of road vehicles. It provides a framework and guidelines for managing risks associated with the electrical and electronic systems in vehicles. The standard was first published in 2011 and has been revised in 2018 to include updates and improvements.

The primary objective of ISO/TS 25237:2019 is to ensure that the safety-related systems in vehicles are designed, developed, and maintained to meet specific safety requirements. These requirements are based on the concepts of risk assessment and risk management. The standard aims to minimize the risks associated with failures in electronic systems, such as those caused by software errors, hardware malfunctions, or external disturbances.

Main Components of ISO/TS 25237:2019

ISO/TS 25237:2019 is made up of several components that collectively contribute to achieving functional safety in road vehicles. Some of these components include:

Functional Safety Concept: This component establishes the foundation of functional safety for a specific project or vehicle system. It involves defining the system's required functions, identifying potential hazards, and determining the necessary safety measures.

Safety Plan: This component outlines the approach to achieving functional safety and provides guidance on the development and validation of safety plans. It includes procedures for hazard analysis, risk assessment, and safety requirements specification.

Safety Requirements Specification: This component includes the technical documentation that specifies the safety functions and safety requirements for the system. It is used to guide the development and validation of the functional safety of the system.

Safety Case: This component is a comprehensive document that provides evidence of the safety functions and safety requirements have been met. It includes information on the hazard analysis, risk assessment, and safety requirements specification.

By following the guidelines and components of ISO/TS 25237:2019, automotive manufacturers can ensure that the safety-related systems in their vehicles are designed, developed, and maintained to meet specific safety requirements. This helps to minimize the risks associated with failures in electronic systems and ensures that the products are safe and reliable for their intended use.
