EC Declara on of Conformity
WHAT DOES A DECLARATION OF CONFORMITY MEAN?
It is a formal declara on by a manufacturer, or the manufacturer’s representa ve, that the product
to which it applies meets all relevant requirements of all product safety direc ves applicable to that
product. It is a sign that a product has been designed and constructed for compliance with relevant
essen al requirements, and has been through the appropriate conformity assessment processes.
A Declara on of Conformity is not a guarantee for safety. However, when properly drawn up
along with CE marking on the product, conformity of the product with the Direc ve(s) quoted on
the Declara on of Conformity may be presumed by suppliers in the distribu on chain and by the
end customer, provided there are no obvious or known defects. Addi onally, market surveillance
authori es, must presume that CE marked products, accompanied by a Declara on of Conformity
comply with the provisions of the Direc ve(s) men oned, unless they have evidence to the contrary
(for example by examining or tes ng the product).
Products subject to more than one Direc ve may come with a single Declara on of Conformity
declaring conformity with two or more Direc ves, or there may be several Declara ons, one for
each Direc ve. However, where a CE marked product is incorporated in another, such as a safety
interlock in a machine, the Declara on of Conformity for the fi nal product may only declare
conformity of the overall fi nal product. In this case the Declara on(s) for any CE marked
component parts should form part of the technical fi le for the complete product.
