| Industry | Mandatory adoption of ISO 14617-3:2021 by | |----------|--------------------------------------------| | Oil & Gas (Offshore) | December 31, 2024 (EU directive 2022/1999) | | Nuclear power | Already enforced as of 2023 (IAEA guide) | | Automotive manufacturing | January 2025 (for all new plant P&IDs) | | Pharmaceutical (GMP) | Already enforced by FDA's 21 CFR Part 11 update |

The standard is designed to reduce ambiguity in technical documentation and improve clarity in CAD libraries.
