I have a paper copy of some parts in German, and electronic versions of the other parts in English/French. As far as I can see, only part 7 (Overview of techniques and measures) mentions Ada in the non-normative annex C. C.4 Development tools and programming languages C.4.1 Strongly typed programming languages NOTE This technique/measure is referenced in table A.3 of IEC 61508-3. Aim: Reduce the probability of faults by using a language which permits a high level of checking by the compiler. Description: ... Typical examples of strongly typed languages are Pascal, Ada and Modula 2. ----------- All safety integrity levels in table A.3 of part 3 (Anforderungen an Software "software requirements") are marked "++" for strongly typed languages. "++" meaning "highly recommended" (besonders empfohlen). Rolf
