Functional safety of electrical/electronic/programmable electronic safety-related systems - Part 3-3: Requirements for object-oriented software in safety-related systems (IEC 65A/1006/CD:2021); Text in German and English
Abstract
Object-orientation (OO) is an ubiquitous concept within the software development realm. It is used for the implementation of safety related functions. Therefore, it is important to identify those properties of object-oriented software where errors can be introduced into the source code during program design and implementation that lead to the failure of security functions. It is made clear which program constructs are to be avoided in an object-oriented program and which are recommended when security is involved. The current version of IEC 61508-3 does not deal with this. The technical specification concerns the above-mentioned situation and is based on the principles already existing in 61508. It is structured according to the OO-specific concepts, and deals with encapsulation, inheritance, polymorphism and dynamic memory management.
