CE marking is obligatory regulatory marking, not a quality mark that can be obtained through a voluntary process. It was created by European legislation as a means of removing technical obstacles to EU-wide movement of construction products subject to the Construction Products Regulations (CPR). It provides visible indication that the products carrying it are entitled to move freely on the single market of all countries of the European Economic Area. It may be verified by Market Surveillance Authorities.
To be entitled to place CE marking on their products, manufacturers must draw up a Declaration of Performance. To do so, tests and verifications must be carried out to determine the performance of the essential characteristics of the products, in accordance with the requirements of the CPR and the applicable harmonized European standards, and to guarantee constancy of performance. These assessments may be performed or inspected by a government-notified body such as Cerib, in the case of many precast concrete products and raw materials for concrete.
