A: Partially. ISO 14617-15 aligns with IEC 60617, but for pure electrical diagrams, IEC 60617 is still the primary standard. For P&IDs, use ISO 14617.
Standards are living documents, updated to reflect technological advancements. In 2025, ISO released major updates to the first two parts, which are the cornerstones of the entire series:
