This is an International standard for functional safety of electrical system in production automobiles. By following this standard, the car manufacturers can avoid or minimize systemic failures. This focuses on the functional safety which ensures that the individual components have been designed to do what they are supposed to. There are also other standards which have a different focus.
Goals of ISO 26262
There are certain goals and aims of these standards which are as follows-
- It provides an automotive safety lifecycle and supports the necessary activities during these phases.
- It covers the aspects of functional safety of the entire development process
- It provides an Automotive specific risk based approach which determines risk classes
- It also provides requirements for validation and confirmation measures to ensure a sufficient level of safety which is to be achieved.
Parts of ISO 26262
ISO 26262 consists of 10 parts which are-
It specifies a vocabulary of terms and definitions for applications in all parts of the standard.
- Management of safety
This provides a standard for functional safety management. It defines standards for over organizational safety management along with the standards for a safety life cycle for the development of automotive products.
- Concept phase
This includes atom definition, analysis and risk assessment with functional safety concept.
- Product development in system level
In this fourth part, general topic for the product development at the system level is explained. It is along with the technical safety concept, system, and testing and safety validation.
- Product development in hardware level
This part deals with topics for product development at the hardware level. It deals with the specification of hardware safety requirements, evaluation of matrix, safety goals violations and hardware verification.
- Product development in software level
This part provides information about the product development at the software level. It specifies software safety requirements and architectural design.
- Production and operation
This is another part which describes planning for production, operation and service.
- Supporting process
This defines objectives for internal processes that are supportive to the safety life cycle processes. It also defines addition consideration that supports accomplishment of general process objectives.
- Safety oriented analysis
This refers to an abstract classification of inherent safety risk in an automotive system. Expresses the level of risk reduction that is required preventing a specific hazard.
The final part is a conscious guideline on ISO 26262 which lists on its scope, normative references and key concepts.
