Gravel Bombardment Test - Procedure
The stone chip resistance of the coating is tested by many small sharp-edged impactors. The bombardment material is defined chilled granulate, which is shot at a certain angle onto the coating with compressed air. The extent of the damage depends on the working pressure, the mass of the shelling material, the shelling time and the construction of the tester.
