One CE mark does not mean one legal assessment. Build a legislation matrix for the product, complete the required conformity route under each applicable act, maintain one coordinated technical evidence set with law-specific mappings, and draw up the single EU declaration required by CRA Article 28(3). The Commission's 2022 Blue Guide likewise explains that where several Union harmonisation acts require CE marking, the marking indicates declared conformity with all of those applicable acts.
Identify Every Applicable CE-Marking Act Before Assessment
Begin with the exact product, intended purpose, hardware and software configuration and market placement. List every Union harmonisation act that applies and provides for CE marking. Do not assume the CRA replaces radio, machinery, safety or other product legislation where those acts remain applicable.
One CE Mark Can Represent Conformity With Several Applicable Acts
The Commission's Blue Guide explains that where a product is subject to several Union harmonisation acts providing for CE marking, the marking indicates that the product is declared to conform to all of those applicable acts. Manufacturers should therefore avoid thinking in terms of a separate CRA CE mark next to a separate machinery or radio CE mark.
One CE Mark Does Not Collapse the Legal Requirements Into One Test
The CRA has its own essential cybersecurity requirements and conformity routes. Another Union act can impose separate safety, electromagnetic, radio, machinery or other requirements. The manufacturer must satisfy each applicable act even though the physical product carries one CE marking.
CRA Article 28(3) Requires a Single EU Declaration of Conformity
Where a product with digital elements is subject to more than one Union legal act requiring an EU declaration of conformity, CRA Article 28(3) requires a single EU declaration covering all such acts. The declaration must identify the Union legal acts concerned, including their publication references.
The Single Declaration Can Still Be Built From Controlled Act-Specific Evidence
A single declaration does not require every technical assessment to be stored in one document. The manufacturer can maintain controlled technical files, test records and conformity evidence by legal act while using a master declaration process that confirms all applicable acts have been completed before issue.
Coordinate Conformity Assessment Routes Law by Law
Determine whether each applicable act allows internal control, requires a notified body, uses type approval or provides another conformity procedure. CRA Article 32 applies only to the CRA conformity route. Another law's third-party assessment does not automatically replace the CRA procedure unless an explicit legal mechanism provides that effect.
Manage Notified-Body Requirements Carefully
A product can involve notified-body activity under more than one Union act. Under CRA Article 30, the CE marking is followed by the notified body's identification number where that body is involved in the CRA full quality assurance procedure based on Module H. Other applicable acts can have their own identification-number rules. The compliance file should record which body acted under which legislation and procedure.
Reuse Technical Evidence With Law-Specific Mappings
Architecture, risk, testing, software, supplier and change-control evidence can support more than one legal act. A shared evidence repository reduces duplication, but each requirement mapping should identify which act, article, annex or standard the evidence supports. Shared documents should not hide a missing law-specific analysis.
Track Harmonised Standards Against the Correct Legal Act
A standard can provide presumption of conformity only within the legal framework and requirements for which its reference has the relevant effect. Maintain the standard reference, version, applicable act and covered requirements rather than maintaining one undifferentiated list of standards for the product.
Do Not Affix or Rely on CE Marking Before All Applicable Requirements Are Satisfied
The CE marking is a declaration tied to the applicable Union harmonisation legislation. Where several CE-marking acts apply, product release governance should prevent market placement until all required conformity assessments, technical documentation and declarations are complete.
Software Products Need the CRA-Specific CE Placement Rule
CRA Article 30 provides that for software products the CE marking is affixed either to the EU declaration of conformity or on the website accompanying the software product, with the relevant website section easily and directly accessible to consumers. Other applicable legislation can impose additional presentation or documentation rules that should be checked separately.
Review Every Applicable Act After Product Changes
A product change can be minor under one law and significant under another. Software updates, radio changes, safety-function changes, remote-service changes or new product capabilities should trigger a multi-legislation review so the manufacturer can decide whether technical documentation, conformity assessment or the EU declaration needs updating.
Build a Release Gate Around the Multi-Law Conformity Matrix
A practical release gate should show each applicable Union act, scope decision, product classification, conformity route, standards used, notified-body status, technical-file status and declaration approval. The product should move to market only when every applicable legal workstream is complete or a documented legal basis explains why an act does not apply.
