Frost resistance

Tiles intended for installation outdoors must be frost proof. The prerequisite for this is low water absorption. Frost resistance is tested in accordance with EN 10545-12 in a stipulated freeze/thaw cycle. Water absorption in detail is governed by the inspection and testing standard EN 10545-3. In the process, the weight in relationship of the dry sample to the water absorbed in percent is represented.
