What is ISO 26262:2019?

ISO 26262:2019 is an international standard for functional safety in the automotive industry. It provides a framework for developing and assessing the safety of electrical and electronic systems within road vehicles. The standard focuses on the management of risk caused by malfunctions in these systems, aiming to minimize any potential harm to people and the environment.

The Purpose and Scope of ISO 26262:2019

The primary objective of ISO 26262:2019 is to address the growing complexity of electrical and electronic systems in automobiles and ensure their safe operation throughout the entire vehicle lifecycle. The standard applies to all aspects of the development process, including design, integration, verification, and production release. It also covers various system elements such as sensors, actuators, processors, hardware, and software.

Key Components of ISO 26262:2019

The ISO 26262:2019 standard comprises ten parts that collectively cover the safety lifecycle of automotive systems:

Part 1: Vocabulary - Defines key terms and concepts used throughout the standard.

Part 2: Management of Functional Safety - Focuses on establishing the organizational and operational framework for functional safety management.

Part 3: Concept Phase - Deals with the initial concept phase of product development and provides guidance on conducting hazard analysis and risk assessment.

Part 4: Product Development at the System Level - Covers the overall system design and integration, requirements specification, and allocation to hardware and software components.

Part 5: Product Development at the Hardware Level - Focuses on the specific requirements for designing and verifying the safety-related hardware elements.

Part 6: Product Development at the Software Level - Addresses the software aspects, including requirements, design, verification, and validation.

Part 7: Production, Operation, Service, and Decommissioning - Deals with the manufacturing, operation, and maintenance phases of the system's lifecycle.

Part 8: Supporting Processes - Provides guidance on supporting processes such as configuration management, change management, and quality assurance.

Part 9: Automotive Safety Integrity Level (ASIL)-Oriented and Safety-Oriented Analyses - Specifies methods for conducting safety and hazard analyses to determine the required safety integrity level.

Part 10: Guidelines on ISO 26262 - Offers additional information and recommendations to complement the other parts of the standard.

The Benefits and Future of ISO 26262:2019
