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).
