Guidance for CE Marking Declarations

Producing a Declaration is one of the integral tasks involved in CE marking a product or machine. The ‘EU Declaration of Conformity’ (which is the most common term used in CE marking) is a document confirming that the product is placed in the market in accordance with the relevant product legislation. This article gives some guidance on creating the document and avoiding simple mistakes.

It is a simple process to generate a Declaration and whilst the purpose of the Declaration is the same, there can be minor variations to the requirements under different Directives and Regulations. Therefore it is always important to refer to the relevant legislation and to pay attention to the detail. An example of these variations can be seen in the Safety of Toys Directive, which requires a colour picture of the toy to be included on the Declaration, whereas other Directives allow it to be voluntary option.

There are also a couple of variations to the title, for example the Construction Products Regulation uses the title ‘Declaration of Performance’ and whereas the Machinery Directive uses the title ‘EC Declaration of Conformity’ for completed machines  (newer Directives use the letters ‘EU’ instead of ‘EC’ as quoted in the Machinery Directive) and ‘Declaration of Incorporation’ for partly completed machines. The specific details required of a Declaration for a Directive or Regulation can typically be found in the appendices of the relevant legislation. The essential layout of a declaration (based upon the new 2016 Directive) can be seen in the example declaration below:


1. No … (Unique identification of the product)

2. Name and address of the manufacturer (or authorised representative):

3.  This declaration of conformity is issued under the sole responsibility of the manufacturer (statement).

4. Object of the declaration (Description allow identification of product for traceability purposes and could include a photograph where appropriate):

5. The object of the declaration described above is in conformity with the relevant Community harmonisation legislation:

– Low Voltage Directive (2014/35/EU)
– Electromagnetic Compatibility Directive (2014/30/EU)

6. References to the relevant standards used (or references to the specifications in relation to which conformity is declared:

– EN 60950-1:2006+A2:2013
– EN 55022:2010
– EN 55024:2010

7. Where applicable, the notified body (name, number) performed (description of intervention) and issued certificate (certificate number).

8. Additional information:

Signed for and on behalf of:………………………….. (Responsible Person)

(Place and date of issue):
(Name, function) (signature):

Note: Always refer to the applicable Product Legislation for the specific requirements for the Declaration.

Even though the layout of the document is straight forward it is easy to make mistakes in the detail of the content. Some common examples of which are included in the following list:

  • Its title is a declaration and not a certificate.
  • It is an EU (or EC) declaration not a CE declaration.
  • A serial number is not compulsory for a declaration but if one is used then it must be stated, TBA is not acceptable.
  • List the correct and applicable Legislative & standards.
  • Ensure correct standard numbers with prefixes are stated. Some Directives/Regulations also require the version of the standard to be listed too.
  • The Declaration should not mislead or create confusion (e.g. to only list the standards for which evidence of conformity has been retained)
  • The person signing should be of an appropriate and relevant position in the company.
  • The declaration must be signed
  • The correct date must be used, for example the date of signature should not predate any of the standards or Legislation stated.

As can be seen there are many simple mistakes that can occur in this short document, however they can all easily be avoided by playing attention to the requirements of the applicable product Legislation and keeping up to date with changes in standards.
