IEC TR 61508-3-3:2025 makes a proposal as to which topics to consider and which methods and techniques to use when designing object-oriented software to ensure suitable quality for use in functional safety applications. Object-oriented languages are perceived as "state-of-the-art" nowadays. Such languages seem to be excluded from use by several statements in IEC 61508-3. However there…

IEC 60794-1-119:2025 applies to aerial optical fibre cables such as all-dielectric self-supporting (ADSS) cables, optical ground wire (OPGW) cables, and optical phase conductor (OPPC) cables that can be exposed to aeolian vibrations. This document defines the test procedures to establish uniform mechanical performance requirements relating to aeolian vibrations. See IEC 60794‑1‑2 for general…

IEC 60794-1-119:2025 s’applique aux câbles à fibres optiques aériens (ADSS, OPGW et OPPC, par exemple) qui peuvent être exposés à des vibrations éoliennes.
