What changes when the answer is yes?
If the event is first EU placing on the market, first EU putting into service, or a substantial modification by a person who is not excluded from manufacturer status under Article 18, the responsible person cannot simply annotate the old file. For machinery and related products, Article 10 requires design and construction in line with Annex III, technical documentation under Annex IV Part A, the relevant Article 25 conformity assessment procedure, an EU declaration of conformity, CE marking, instructions, and retention of the technical documentation and declaration for market surveillance authorities.
For partly completed machinery, the evidence route is different: Article 11 points to Annex IV Part B technical documentation, an EU declaration of incorporation, and assembly instructions. Do not replace that with a machinery declaration unless the product has become complete machinery or a related product.
- Update the technical documentation, risk assessment, drawings, calculations, test records, standards mapping, safety-control evidence, software or programming-logic evidence where relevant, instructions, and declaration affected by the change.
- Use Article 25 to select the procedure: Annex I Part A categories require notified-body routes; Annex I Part B categories can use internal production control only when the applicable harmonised standards or common specifications cover all relevant essential health and safety requirements; non-Annex I machinery uses module A.
- Keep the old evidence linked but clearly mark what remains valid, what was superseded, and what was newly assessed for the modified configuration.
Articles 10, 11, 18, and 25 ground the manufacturer obligations, partly completed machinery evidence, substantial-modification responsibility, and conformity assessment choices.
