What is a Declaration of Conformity?

A DoC is the manufacturer’s legal statement that its product complies with all relevant EU directives and regulations. The document is mandatory for affixing the CE marking and is kept in the technical file for at least 10 years.
It must include the manufacturer’s details, a description of the product, and the list of applicable directives/regulations and harmonized standards. The wording and order of fields are defined by Annex III to Decision 768/2008/EC. It is signed by an authorized person and translated into the languages of the countries of sale.
