A side-by-side comparison of Conformity Assessment and CE Marking. Understand how the compliance evaluation process differs from the mark signaling that applicable EU requirements have been met.
Quick Verdict: Use Conformity Assessment for the process of demonstrating requirements are met; use CE Marking for the resulting conformity mark where applicable.
Conformity Assessment defines process of determining whether a system, product, or process satisfies specified legal or technical requirements.
Context: Most relevant when describing the evaluation process used to demonstrate compliance before market placement or use.
CE Marking defines conformity mark indicating that a product or AI system meets applicable requirements under relevant European Union law.
Context: Most relevant when describing the visible or formal mark associated with demonstrated EU conformity.
| Aspect | Conformity Assessment | CE Marking |
|---|---|---|
| Regulatory purpose | Conformity assessment is the process of determining whether requirements are satisfied. | CE marking is the mark indicating that applicable EU requirements have been met. |
| Trigger point | Performed before relevant market placement or use when required. | Applied after the required conformity assessment and compliance steps are completed. |
| Required evidence | Requires evidence against specified legal or technical requirements. | Depends on the underlying assessment, documentation, and compliance evidence supporting the mark. |
| Responsible actor | The provider is commonly central to demonstrating compliance, with notified-body involvement where applicable. | The provider is commonly responsible for ensuring the mark reflects completed applicable compliance obligations. |
| Audit implication | Auditors review the assessment scope, criteria, evidence, and conclusion. | Auditors verify that the mark is supported by a valid conformity process and documentation. |
In practice, CE marking is the visible compliance signal, but conformity assessment is where the real evidence work happens.
Treating CE marking as proof without checking the underlying assessment record.
Starting CE marking discussions before identifying applicable requirements and assessment route.
Confusing a compliance process with the symbol or mark that follows it.
Use Conformity Assessment when discussing the evaluation process for proving that an AI system, product, or process satisfies specified requirements. It is the right term for evidence review, assessment procedures, and pre-market compliance gates.
Use CE Marking when discussing the conformity mark that signals compliance with applicable EU requirements. It should be used only in connection with the underlying assessment and documentation that support the mark.
Under the EU AI Act, high-risk AI systems may require conformity assessment before being placed on the market or put into use. CE marking is not the assessment itself; it is supported by evidence generated through the applicable process.
No. Conformity assessment is the process, while CE marking is the mark indicating that applicable requirements have been met.
It reviews whether a system, product, or process satisfies specified legal or technical requirements, including relevant AI obligations where applicable.
Because evidence must support compliance before market placement or use where required, and the CE mark should be backed by that evidence.
