ISO 26262 - "Road vehicles-Functional Safety" is a standard for the automotive industry, administered in an attempt to prevent potential accidents due to systematic and random failures in the Electrical/Electronic-system. In general, requirements in industry is often of poor quality and considering the strong emphasis on requirements management in ISO 26262, we believe that there is a strong need for guidance and experience-sharing on the speci cation of requirements in practice. We therefore present a reference example on the application of ISO 26262 in practice, where we perform a breakdown of a Safety Goal of an industrial system down to Software Safety Requirements on the C-code implementation. As a basis for structuring and formulating the requirements, we use the concepts of contracts and port variables.
