| Resumen: | This part of ISO 20567 specifies three methods for the evaluation of the resistance of automobile finishes and other coatings to chilled iron grit projected onto the surface under test to simulate the impact of small stones. The stone chip resistance of the coating under test is checked by projecting a large number of small sharp-edged bodies onto it in rapid succession. The material used in the test is chilled iron grit which is projected onto the coating at a defined angle using compressed air. The extent of the damage caused also depends on the pressure level, the mass of the projected material, the duration of the bombardment and the construction of the test apparatus. Loose fragments of coating material are removed. The extent of the damage is determined by comparison with reference pictures. |
