Declaration of Performances (DoP)

The letters 'CE' appear on many products traded on the extended Single Market in the European Economic Area (EEA). They signify that products sold in the EEA have been assessed to meet high safety, health, and environmental protection requirements.

CE marking applies to products, ranging from electrical equipment to toys and from civil explosives to medical devices. But not all products sold in the EU need to bear CE marking. Construction Products do need CE marking.

The Construction Products Regulation (CPR) lays down harmonised rules for the marketing of Construction Products in the EU and defines the conditions for the CE marking thereof. This Regulation provides a common technical language to assess their performance.

Sealants are among the Construction Products concerned by this regulation.

Since the 1st of July 2014, all sealants for non-structural use in joints within buildings and pedestrian walkways need the CE marking.


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

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)  is placed on the market.

Harmonised European Standards provide a solid technical basis for manufacturers for testing the performance of their products.

The hEN 15651 series of standards for sealants for non-structural use in joints in buildings and pedestrian walkways deals with :

  • EN 15651-1: Sealants for facade elements
  • EN 15651-2: Sealants for glazing
  • EN 15651-3: Sealants for sanitary joints
  • EN 15651-4: Sealants for pedestrian walkways

EN 15651-5 specifies procedures for the evaluation of conformity and marking.

All Elkem Silicones' sealants covered by this standard have been tested and a copy of the DoP of each product which is made available on the market can be downloaded from here.
