Declaration of Performance (DoP) - a document containing information on a product type and its performance. On 1 July 2013, on the basis of the Regulation no. 305/2011 (CPR) of the European Parliament and Council (EU) of 9 March 2011, a DoP replaced a certificate of conformity.
A DoP confirms that a construction product has been approved for marketing. A Declaration of Performance is attached to products subject to a Harmonised Technical Specification or a European Technical Assessment
Issuing a Declaration of Performance and marking products with the CE mark means that a manufacturer is responsible for product conformance to the declared parameters.
These are documents issued on the basis of tests by authorised research units which define the fire resistance classes(e.g. EI 30, EI 60) for tested building elements, e.g. as regards drywall systems - partition walls, curtain walls, suspended ceilings, attic linings and dry screeds.
