When the load rod is displaced in the axial direction, a load is applied to the specimen, and the reaction force is received and supported by the fixed rod. At the same time, the amount of deformation of the test piece is measured by a displacement meter. Therefore, the specimen can be material tested under high temperature and high pressure conditions in an autoclave. In this type of high-temperature, high-pressure material testing machine, when calibrating the displacement gauge, the displacement gauge has conventionally been calibrated under atmospheric pressure. However, when material testing a specimen under high temperature and high pressure conditions inside an autoclave, the temperature and pressure inside the autoclave will increase.
This will inevitably affect the measured value of the displacement meter. For this reason, even if the displacement meter was calibrated under atmospheric pressure, it was not possible to accurately measure the amount of deformation of the test piece.

As shown in Figure 3, the amount of displacement (5) is determined by using the notch (IG) for the material test of the test specimens (T, P) and the temporary displacement (
The amount of deformation of the test piece (T, P) is measured by a strain gauge (15) attached to the test piece (14). The leaf spring (14) is attached to the stand (9) and is pre-deflected by a preload. And a leaf spring (1

8) sandwiched between and held. When testing the material of the test piece (T, P), the test piece (T, P) is notched (IG).
is connected to the load rod F' (2) and the fixed rod F (3>) on both sides of the stand. Each stand (8), (9) is fixed to the test specimen (T, P) on both sides of the notch (j3). .Load lot (2)
When the specimen (T, ))) is displaced in the axial direction, a load is applied to the specimen (T, )), and the reaction force is received and supported by the fixed rod (3). The load acts in the direction of arrow 19), deforms the test piece (T, P), opens the notch (13) by 1'', and generates a crack (20). I wanted to use a displacement meter (5
) stands (8) and (9) are relatively displaced in response to the deformation of the test plate (T, P), thereby relaxing the deflection of the plate spring (14) and changing its strain. Strain r-shi (15
) detects the strain in the plate spring (14) and detects the strain on the test piece (T, P
) to measure the amount of deformation. Therefore, the test piece ('I'P) is subjected to a material test under high temperature and high pressure conditions in the autoclave (1).

(7) and displace the load rod (2) in the axial direction. The load rod (2) is displaced by the weight of one block (6). Each block (6), (7) is guided by a guide bin (11) and is relatively displaced in the axial direction of the load lot (2). Therefore, each stun F (8), (9) of the displacement meter (5) is displaced relative to the axial direction of the load rod (2), and the deflection of the plate spring (14) is alleviated. The strain gauge (15) detects the strain in the plate spring (14) and measures the displacement of the load rod (2).Therefore, the displacement of the load rod (2) is determined by the difference. By comparing the measured value of displacement (5) with the measured value of displacement (5), it is possible to calibrate the displacement meter (5) under the high temperature and high pressure conditions of Au L-Crepe (1).
