Revision and traceability — Reference record
A useful revision explains what changed, why the record changed and which figures or component tables are affected.
| Reference record | Working notes |
|---|---|
| Overview | Revision and traceability |
| Practical example | Keep a superseded drawing readable and point to the current revision without overwriting its history. |
| Limits and interpretation | A newer document date does not by itself establish technical approval. |
| Document control | Reference edition 2026.11 |
Measurements and examples are descriptive, not acceptance criteria.
