Safety management

To make a product functionally safe, systematic failures have to be avoided, and systematic and random hardware failures have to be controlled.

ISO 26262 - Functional safety in the automotive sector

 

Since November 2011, development in the automotive sector has been subject to the ISO 26262, which is the relevant standard for functional safety. Although the scope of the standard is limited to passenger vehicles up to 3,5 tons, the standard is increasingly applied in the field of heavy goods vehicles as state-of-the-art.
 

The ISO 26262 is based on the IEC 61508, which is considered the fundamental standard of functional safety. For the standard applicable in the automotive sector, sector-specific issues have been adapted, as for instance distributed development, mass production and the basic idea of developing and operating a product safe on its own terms. 

Considering the requirements chapters of the ISO 26262, a clearly defined concept phase as well as the development on system level and a detailed description of activities in hardware and software development can be recognized. Furthermore requirements to production, operation and disposal are described in the ISO 26262.

In the automotive sector, the ISO 26262 is seen as process framework. Automotive manufacturers, Tier1- and Tier2-suppliers integrate it into their process landscapes suitably for the products to be developed and produced. 

 

 

Safety Lifecycle ISO 26262

 

Even if the ISO 26262:2011 does not contain discipline-specific requirements to processes and metrics for mechanical hardware development as it does for software and electrical hardware, the safety lifecycle of the ISO 26262 implies these requirements by the pictured link "Allocation to other technologies".
