| » Our production complies with European standard UNI EN 1339-2004, indicated by the CE marking on the tiles. Mariotti has obtained a “Produktzertifikat“ issued by the famous German institution “Güteschutz Hessenbeton e.V.” (DIN 18500, EN 1339) since 1998. A Product Certificate is only issued after external tests on sample tiles and continuous factory testing of the whole production. Mariotti monitors absence of radioactivity and hardness and checks also tolerances. |
