Clients applying for CE certification often ask two core questions: Does CE certification have an expiration date? What documents are required?

To answer the first question simply: CE certification has no fixed expiry date like traditional certificates. It remains valid as long as the product design stays unchanged and the applicable harmonized standards are not updated. However, you cannot ignore compliance work after signing the Declaration of Conformity (DoC) and affixing the CE mark. Any product modification or standard revision will invalidate the original compliance status.

For the second question, CE requires more documents than FCC SDoC. Covering multiple directives, CE imposes more detailed requirements on technical documentation.

1. Validity Rules of CE Certification

CE is not a certification model of "application, issuance and renewal" such as FCC ID. It is a complete compliance system based on EU directives and harmonized standards. Manufacturers can place products on the EU market after signing the DoC and applying the CE mark.

The continuous validity of CE compliance depends on two prerequisites:

·No product modification: The CE status remains valid if the product design, key components and circuit solutions are identical to the version used for testing and declaration. If you replace critical components, revise circuit designs or adjust structures that affect safety or EMC performance, a re-evaluation is mandatory. Even replacing components of the same specifications from different brands requires full records and compliance assessment in the Technical Construction File (TCF).

·No standard update: EU harmonized standards are revised on a regular basis. Official EU Journals announce standard updates and transition periods, during which old and new standards are both acceptable. Once the transition period ends, old standards are fully phased out, and compliance documents issued based on obsolete standards become invalid automatically.

  2. Required Documents for CE Certification

Laboratories will request the following documents before conducting tests:

·Product Specification: Clearly state product functions, operating voltage, clock frequency, interface types and other basic parameters. Labs determine applicable directives and test schemes based on this file. Complete circuit schematics covering power modules, control circuits and interface circuits are also required. PCB layout drawings are equally important, as component placement and wiring directly affect EMC performance.

·Bill of Materials (BOM): List the model and specifications of all key components. Laboratories will verify the compliance certificates of relevant parts. A detailed user manual including operation guidelines, safety warnings and installation instructions is mandatory. For consumer products sold in EU member states, user manuals and safety alerts must be printed in the local official language (German for Germany, French for France, etc.). Professional industrial equipment is exempted from this rule under specific regulations.

·Label and Nameplate Drafts: Product labels must display manufacturer information, model number, electrical parameters and the CE mark. For RED radio frequency devices, details of the EU Authorized Representative (EC REP) must be marked on the product or outer packaging. For general consumer goods, EC REP information can be printed on product labels, outer packages or user manuals.

·Test Samples: Prepare 2 to 3 units for regular products to complete EMC and LVD tests continuously. For wireless products under the RED directive with complex test conditions, prepare no less than 3 samples.

After tests are passed, the laboratory issues official test reports. Together with the TCF and DoC, these form the complete compliance documents for archiving.

  3. Contents of Technical Construction File (TCF)

The TCF is the core document of CE certification, far more comprehensive than FCC technical files:

·Product Description: Including functions, applications, technical parameters, product photos and exploded views.

·Design & Manufacturing Documents: Circuit schematics, PCB layouts, structural drawings, BOM and compliance certificates of key components.

·Risk Assessment Records: Electronic and electrical products must complete risk analysis in accordance with corresponding standards such as EN 62368-1 or EN 60335. This is a unique requirement for CE and does not apply to FCC. Note that ISO 12100 is only for mechanical equipment, not electronic and electrical products.

·List of Applicable Directives & Standards: Specify all EU directives, corresponding harmonized standards and version numbers.

·Test Reports: Full reports for EMC, LVD, RED and other required tests.

·RoHS Related Documents: For products subject to RoHS 2.0, attach RoHS test reports and material compliance declarations.

·Declaration of Conformity (DoC): Signed and issued by the manufacturer.

·EC REP Information: Name and address of the EU Authorized Representative must be shown on the DoC and packaging if applicable.

If the product has passed type examination by an EU Notified Body (NB), the NB type approval certificate must also be archived. This certificate also needs re-evaluation when products or standards are updated.

The TCF must be retained for at least 10 years starting from the date when the last batch of products is launched on the EU market. After the implementation of GPSR, the TCF requires dynamic maintenance. Any replacement of key components, supplier changes or product revisions must be fully recorded, together with change assessment conclusions and supporting documents.
