Abstract

PURPOSE:To test heat resistance with high accuracy by providing a heating chamber, support means, pressing means, temperature detecting means, and control means, etc. CONSTITUTION:The heating chamber 2 is heated by a heater 4. The heating chamber 2 is provided with the support means 5 and a test-piece is supported. Further, the part of the test-piece on the means 5 is pressed by the pressing means 12 and the temperature detecting means 11 is provided individually nearby the test-piece supported by the means 5, and the control means 6 controls the heater 4, etc., in response to the output of the means 11. Then the means 6 controls the heater 4, etc., so that the detected temperature of the heater 4, etc., is fixed. Consequently, the test-piece supported by the means 5 is heated through a heat conductive medium to the same temperature. An error in measurement result due to the heat expansion or contraction of the means 5 and 12 is made as small as possible to take a measurement with high accuracy.
