Declaration of Performance (DoP) and CE marking

Definition and objectives

The Declaration of Performance (DoP) is the key concept in the Construction Products Regulation (CPR).

The DoP serves to deliver the information about the essential characteristics of the product that a manufacturer wants to make available on the market.

The manufacturer shall draw up a Declaration of Performance when a product covered by a harmonised standard (hEN) or a European Technical Assessment (ETA) is placed on the market.

The manufacturer, by drawing up a DoP, assumes the responsibility for the conformity of the construction product with the declared performance.

A copy of the DoP of each product which is made available on the market shall be supplied either in paper form or by electronic means or on a website.

Some manufacturers make available to potential customers the copy of DoP(s) drawn up for their product(s) or performance information on their products in another format. Such information may help the potential user to decide to buy, amongst all the products available on the market, the one which is fit for the use he intends to give to such product.

The DoP constitutes then the key element in the functioning of the Internal Market for construction products by providing it with the necessary transparency and by establishing a clear system of allocation of the responsibilities between actors.
