CEマーク
To affix the CE marking to a construction product, the manufacturer is obliged to draw up a "Declaration of Performance" (DoP) when a construction product is covered by a harmonized standard or conforms to a European Technical Assessment. Any information about the product's performance in relation to the essential characteristics may be provided only in the form of a declaration of performance. The CE marking shall be applied to the product itself and where this should not be possible to the packaging or accompanying documents.
