The Construction Product Regulation (CPR) is intended to ensure reliable information on construction products in relation to their performance. This is achieved by providing a “common technical language”, offering uniform assessment methods for the performance of construction products.

  These methods are compiled in harmonised technical specifications. This common technical language is to be applied by:

 - the manufacturers when declaring the performance of their products, but also by

 - the authorities of Member States when specifying requirements for them and by

 - their users (architects, engineers, constructors, etc.) when choosing the products that are most suitable for their intended use in construction works.

  All cables installed permanently in constructions must be CE marked. National Regulators can define for special circumstances the maximum length of cable whose contribution to fire is considered negligible and therefore accepted without any CE marking or with a level of performance lower of what required for the specific construction. In such a case the cable must be as short as possible and connected in the fire compartment it enters.

  The Declaration of Performance is a key part of the Construction Products Regulation. It provides information on the performance of a product. Each construction product covered by a European harmonised standard or for which a European Technical Assessment has been issued needs this Declaration and has to be CE marked. This helps increase transparency and improves the functioning of the Single Market.

  The DoP is a document drawn up by the manufacturer for every product covered by the CPR following regulatory guidelines, which:

 - identifies the product

 - states its intended use

 - its essential characteristics as given by its declared performance (for cables by classes of performance for reaction to fire, classes of performance for resistance to fire and release of dangerous substances )
