PROBLEM TO BE SOLVED: To provide a deterioration factor exposure amount measuring method of a synthetic resin material capable of measuring the deterioration factor exposure amount of the synthetic resin material (existing material) actually exposed to the deterioration factor, by simple means without destroying the synthetic resin material.SOLUTION: Fine irregularities are formed on a surface part of a synthetic resin material, and the synthetic resin material is exposed to a deterioration factor. Then, the degree of smoothness on the surface part is measured, and the exposure amount of the deterioration factor is measured from data of a correlation, which was acquired beforehand, between the deterioration factor exposure amount and the degree of smoothness on the surface part.SELECTED DRAWING: None |
