OZONE DETERIORATION EVALUATION METHOD AND EVALUATION SYSTEM OF VULCANIZED RUBBER MATERIAL

摘要

An ozone deterioration method of a vulcanized rubber material is provided which can enable understanding the change over time of ozone deterioration with good accuracy while decreasing the work man-hours. A vulcanized rubber material test sample S is arranged in a test tank 2 with a prescribed ozone concentration under predetermined arrangement conditions and attached to a fixed frame 3; the surface of the test sample S, in the state arranged in the test tank 2, is imaged with fixed-point imaging over time by at least one camera device 5 to acquire digital image data 6x, and change in the surface state of the test sample S between multiple time points is understood by analyzing the acquired image data 6x with a computing device 8.
