The objective of the Construction Products Regulation EU 2011/305 is not to define the safety of construction products, but to ensure that reliable information is presented in relation to their performance - and all this in a harmonized manner across Europe.
The product shall be followed by a Declaration of Performance with a common technical language, as specified in the corresponding harmonized European product performance standards. The actual requirements still are specified by each EU Member State on its own.
CE marking in this context is the key tool and means just and only that a Declaration of Performance (DoP) following the product was drawn up in accordance with the specifications in the corresponding harmonized European standard.
