TBTSTM-B is designed referring to the standard EN 14157 Natural stone test methods - Determination of the abrasion resistance.
It is a necessary device designed to evaluate the wear resistance and durability of premium construction materials. By subjecting specimens to standardized friction conditions, the machine accurately determines the volume loss, providing critical data for quality control, research, and product certification.
