Development of the 2nd Edition of the ISO 26262

In 2011 the automotive standard ISO 26262:2011 for the development of safety critical systems has been officially released. This standard has been successfully applied by various companies in the automotive supply chain and is the framework of the development of safety related systems and of their components. There is a regulation of the International Standardization Organization (ISO) that valid and published standards shall be periodically reviewed. Now the time has come to update and extend the existing standard, to make it applicable for future systems and technologies. The main motivations for the 2nd edition of ISO 26262: are the experiences gathered with the 1st edition; the extension of the scope to other vehicle categories; the inclusion of a semi-conductor guideline and the inclusion of guidance on fail-operational systems. This paper presents the key changes and updates and the motivation behind them.
