ISO26262 FUNCTIONAL SAFETY
ISO 26262 specifies a vocabulary (a Project Glossary) of terms, definitions, and abbreviations for application in all parts of the standard. ISO 26262 provides a standard for functional safety management for automotive applications, defining standards for overall organizational safety management as well as standards for a safety life cycle for the development and production of individual automotive products. ISO 26262-4:2011 specifies the requirements for product development at the system level for automotive applications, including the following: requirements for the initiation of product development at the system level, specification of the technical safety requirements, ISO 26262:2018 Part 5 – Product development at the hardware level Hardware development is part of system development in the safety lifecycle and runs parallel to software development.

ISO 26262 is a series of standards regulating electrical and electronic components installed in road vehicles with a focus on their safety. ISO-26262-6 is part of that series focusing on "Product development at the software level" and covers software application design, production and testing. Supporting Processes. ISO 26262 defines objectives for integral processes that are supportive to the Safety Life Cycle processes, but are continuously active throughout all phases, and also defines additional considerations that support accomplishment of general process objectives. The safety lifecycle of any ISO 26262 compliant automotive application development begins with determination of ASIL (Automotive Safety Integrity Level). Determined through hazard analysis and risk assessment of automotive component, the ISO 26262 ASIL rating helps in identifying safety measures required to reduce the potential hazards. Defines standards for the safety lifecycle of individual automotive products Concept phase Product development at the system level, hardware level, and software level The ISO 26262 does not provide a best practice for distributing failure modes, especially when talking about semiconductors. Therefore, a detailed analysis of all safety-related blocks upon their failure modes shall be performed as a preparative step for an FMEDA.
