PROBLEM TO BE SOLVED: To provide a method for evaluating chipping-resistant performance of a rubber crosslinked body, which is excellent in correlation with the chipping-resistant performance in a practical vehicle.SOLUTION: A blade 12 is pressed into a surface 2 of a rubber sample in an approximately vertical direction until a slit is generated on the surface of the rubber sample, so that chipping-resistant performance is evaluated by a press stroke or press force at the time of generation of the slit or by external work volume until the time of generation of the slit.SELECTED DRAWING: Figure 2 |
