Formulation of comments and potential non-conformities; – formulation of an assessment in the form of an evaluative report. 2. SSIL management In Chapter 4, we shall present the approach to safety management as proposed by CENELEC 5012x. In this section, we shall focus on how to identify the SSIL on the basis of the SIL, and outline the general ideas. 1. SSIL attribution The management of software safety involves management of the SSIL. As indicated above, the value of the SSIL ranges between 0 (no impact whatsoever on safety) to 4 (major impact on safety).

These concepts will be explored in detail in Chapter 10. 1. Introduction The aim of this chapter is to present the concepts of risk, undesirable events, accidents, severity, frequency and level of risk. Here, we are able to set out a clearly-defined lexicon, and also point out the differences between the vocabulary used in different domains. For example, in aeronautics, we speak of the Design Assurance Level (DAL), and in other domains, the concept used is the Safety Integrity Level (SIL). For the automotive industry, the concept of ASIL1 is used, and there are two new criteria – exposure and controllability – which play a part in the definition of the risk level.
