The DoP (Declaration of Performance) is a key part of the European Construction Products Regulation. It provides information on the performance of a product.  

 Whilst CE marking indicates that a construction product conforms with its declared performance and that it has been assessed according to a harmonised European standard (hEN) or a European Technical Assessment (ETA) has been issued for it.

For construction products, the Construction Product Regulation (CPR), issued by the European Commission applies in Europe. 

The Construction Products Regulation (CPR) lays down harmonised rules for the marketing of construction products in the EU. The Regulation provides a common technical language to assess the performance of construction products. It ensures that reliable information is available to professionals, public authorities and consumers, allowing them to compare the performance of products from different manufacturers in different countries.

If the harmonised European standards (hEN) for any product already exist, the manufacturer has to CE-mark the product and attach a Declaration of Performance (DoP) to it. 

If hEN is not available for a certain product, and a manufacturer decides to obtain an ETA, they still have to develop a DoP and obtain CE marking from EU commissioners on the basis of tests conducted by accredited laboratories.

One should keep in mind that CE marking means that the product was tested according to standardised European norms, but it says nothing about its performance and field of application. It is merely an indication that it conforms to the performance described in a DoP.  

A DoP provides information on the performance of the product. This helps to increase transparency and declares the fitness for use of the product. A Declaration of Performance (DoP) describes the construction product’s characteristics which are relevant for the requirements of a building, such as the extent to which it is virtually airtight or fire resistant. 

All HILTI firestop products have an ETA and hence the CE marking and corresponding DoPs. This allows us to market them in Europe and help our customers make informed choices. Our ETAs contain the detailed field of application, which is the key factor for selecting and applying the right product according to the application requirements.
