Declaration of performance

Explained

Under Regulation (EU) No 305/2011 the manufacturer of a construction product covered by a harmonised standard or a European Technical Assessment draws up a declaration of performance (DoP). It states the performance in relation to the essential characteristics of the harmonised technical specification, and by drawing it up the manufacturer assumes responsibility for that performance. It is the basis for affixing the CE marking. Delegated Regulation (EU) No 157/2014 allows it to be made available on a website if five conditions are met: the content is not changed, the website is maintained and available, access is free for ten years after the product is placed on the market, recipients get instructions on how to find it, and the product type code links product and declaration. Regulation (EU) 2024/3110 replaces the DoP family by family with the declaration of performance and conformity.
