The characteristic values of damping materials are variant on frequency and temperature. We measure the characteristic values(loss factor, young\\`s modulus) of damping materials in vibration test. We can not measure characteristic values of damping materials by themselves. So, we proposed a method, sticking damping material to thin steel beam and measuring of characteristic values of damping material on frequency and temperature. We didn\\`t use constraining layer but we measured characteristic values on conditioning temperature.
