The compressive strength class according to DIN 105-100 Table A.10 indicates the smallest individual value of the minimum compressive strength in N/mm². According to these values, bricks are assigned to compressive strength classes 4, 6, 8, 10, 12, 16, 20, 28, 36, 48 and 60. These values and the converted average minimum compressive strength (= value of the compressive strength class multiplied by 1.25) are considered minimum values for the stone compressive strength.
