A number of products must have a CE marking before they are eligible to be marketed, sold and used in the EU countries. This includes construction products, which are included in a harmonised standard or a European technical approval.
The CE marking can be perceived as an agreement based on trust between authorities and business. The marking indicates that the characteristics of the construction products are declared in a consistent manner, so they can be sold on the European market without new demands for national testing and approval. However, it cannot be considered a quality label.
Although a product has a CE marking, national building regulations may exist, so the product can be applied only to a limited degree in a country.
