    It consists of four hollow cylinders with one end sealed. For aggregate particles ranging in size from 4 to 14 millimeters, the inner diameter of the cylinders is 200 ± 1 millimeters, and the effective length is 154 ± 1 millimeters. The cylinders are made of stainless steel (Z 2 CN 18-10) with a wall thickness of no less than 3 millimeters. They are mounted on two horizontal shafts, with each cylinder dedicated to a single test. The interior of each cylinder must be free from any irregularities or protrusions caused by welding or fastening methods. The cylinders are sealed with flat covers that are 8 millimeters thick, and the sealing is ensured through the joints on the covers. The abrasive material comprises stainless steel spherical balls with a diameter of 10 ± 0.5 millimeters, designated as Z 30 C 13. The steel balls are passed through two parallel rods spaced 9.5 millimeters apart, or their mass is measured in groups of 10 used balls; the total mass of each group must not be less than 34 grams, allowing for a rapid verification of the ball diameters. An electric motor—rated at approximately 1 kilowatt—must ensure that the cylinders rotate at a constant speed of 100 rpm ± 5 rpm. A device is included to automatically shut off the motor at the end of the test.
