CPR certificates in accordance with the Construction Products Regulation (CPR) are issued as a basis for CE marking of construction products where the European Construction Products Regulation requires such certification. The regulation specifies various systems for assessing and declaring construction products' properties (Assessment and Verification of Constancy of Performance, AVCP). This system applies to the individual construction product and is specified by the harmonized product standard of the product type, or in the ETA (European Technical Assessment) for a specific construction product. For systems that require a CPR certificate, this applies to either certification of the factory's production control or certification of the product itself. SINTEF Building and Infrastructure is designated as a certification body for a number of construction products.
