Abstract
According to the present technology, an impact test in which an impact application member is made to free fall onto a test sample of a plurality of types of rubbers having different physical properties is performed under prescribed test conditions; data for at least one of three items including a loss energy that is absorbed by the test sample when the impact application member collides with the test sample, a thermal energy that is generated at the test sample, and an indentation amount into the test sample by the impact application member is acquired; and an optimal test sample is selected from the respective test samples on a basis of a ranking of the superiority of the respective test samples with respect to the item(s) for which data was acquired.
