Title:
METHOD FOR CALIBRATING THERMOPHYSICAL PROPERTY MEASUREMENT DEVICE, CALIBRATION PROGRAM, STORAGE MEDIUM, AND REFERENCE SAMPLE
Document Type and Number:
WIPO Patent Application WO/2022/004888
Kind Code:
A1
Abstract:
[Problem] To provide a calibration method, etc., for performing calibration so that there is no difference in measurement results due to individual differences between a plurality of thermophysical property measurement devices or discrepancies between measurement methods. [Solution] In this method for calibrating a thermophysical property measurement device, processing is performed so that a reference thermophysical property value, which is a measurement result from a reference device 1, and a subject thermophysical property value, which is a measurement result from a subject device 20, are the same result. A reference sample 4 adjusted to a reference temperature is mounted in the subject device 20, and the subject device 20 is operated to measure the thermophysical property value of the reference sample 4. At this time, the temperature during measurement, which is the temperature of the surrounding environment of the reference sample 4, is measured by a temperature sensor 30 of an additional temperature control unit 29, the difference between the subject thermophysical property value and the reference thermophysical property value at the temperature during measurement is calculated to derive a correction value for the subject device 20, and calibration is performed using the correction value. Alternatively, the correction value may be derived with the temperature adjusted so that the temperature during measurement is the same as the reference temperature.
