Machinery Directive Annex III: Rules for the CE Marking

Annex III governs the CE mark's graphic form; a correct logo does not itself establish machinery conformity.

RELATED DECISION GUIDES

Continue with the relevant decision step

Direct answer

Annex III governs the CE mark's graphic form; a correct logo does not itself establish machinery conformity. Complete the required assessment, technical file, instructions and declaration before marking. Preserve the prescribed proportions and ensure the machine's marking remains identifiable and legible.

Decision and evidence

Check placement and accompanying machine identity against the relevant rules. Add a notified body number only where the applicable procedure requires it, rather than copying another label.

Technical basis

For machinery, risk assessment, essential health and safety requirements, the technical file, declarations and CE marking must form one traceable chain under the applicable machinery legislation.

Practical questions

Can a single custom-built machine be exempt from CE requirements?

Producing one unit does not by itself create a general exemption. Assess the product, placing on the market or into service, and applicable exclusions. Custom design does not remove necessary files, risk assessment and declarations. Separate testing, technical assessment and any third-party stages according to the machine.

Will renewing paperwork solve recurring safety failures?

First control the hazard and identify affected machines. Investigate combined design, component, installation and use factors. Assess corrections, user information and cooperation with authorities. A newly dated document does not repair a technical defect; conformity claims and files need evidence of actual correction.
