Process of CE Marking ( self-certification mode )

1. Study which directive is applicable
2. Determine which standards are applicable
3. Test your product to ascertain if it complies
4. Make a test report
5. Make Technical Construction File:
Technical documentation - The manufacturer must draw up a technical file (technical documentation).
The technical documentation is intended to provide information on the design, manufacture and operation
of the product. This is widely called 'Technical Construction File'.
6. Make a declaration that the product conforms to the standard(s).
7. Apply the CE mark on your product
 

Process of CE Marking ( third party-certification mode )

1. The steps essentially remain the same.
2. In this case, the test must be made by a Notified Body.
3. The test report and declaration will be made by the Notified Body.
4. The CE Mark will carry a number linking to the Notified Body.

How to reproduce the CE Mark ?

The CE mark is covered by Council Decision 93/465/EC. Annex B(d) gives these guidelines:
1. The CE conformity marking must consist of the initials 'CE' taking the following form:


If the CE conformity marking is reduced or enlarged the proportions given in the above graduated drawing must be respected.
2. Where the directive concerned does not impose specific dimensions, the CE marking must have a height of at least 5 mm.
3. The CE marking must be affixed to the product or to its data plate. However, where this is not possible or not warranted on account of the nature of the product, it  must be affixed to the packaging, if any, and to the accompanying documents,  where  the directive concerned provides for such documents.
4. The CE marking must be affixed visibly, legibly and indelibly.
