Type tests were carried out at the Institute of Glass and Ceramics in Warsaw and on the basis of these tests Declarations of Conformity were drawn up for each type of product separately.
As a result of a change in legislation, the Declaration of Conformity was replaced by the Declaration of Performance for products manufactured after 01.07.2013.
Declarations of Performance are a guarantee that the product has been manufactured in accordance with the requirements contained in the declared standard and has the physical and chemical properties specified by the standard.
