We prepared 7 cavity-backed disk plates which were same to baseline calibration plate used in COR test. Their membrane thickness increased by 0.2mm from 1.8mm to 3.0mm. CT(Characteristic Time)s were tested by a pendulum test instrument and CORs were measured through COR test using an air gun. The relation between CT and COR agreed with their linear characteristic described in "Technical Description of the Pendulum Test" by R&A and USGA for the thickness of 2.6mm or more. On the other hand, COR was constant and CT only increased for 2.4mm or less. Finally estimation of CT of the plates was simulated. As a result, we show that it is possible.
