PURPOSE:To enable a plurality of continuous tests in the same atmosphere, by suspending test pieces from the same circumference of a rotary disc intermittently rotating in an autoclave in a test environmental atmosphere at predetermined intervals so as to be capable of downwardly pulling the same at a specific position. CONSTITUTION:The lower flange 2 of an autoclave 1 is fixed to a base plate 3 to hermetically close the interior of said autoclave 1 and an intermittently rotating disc 7 is placed on the support ring 5 supported by a plurality of load receiving levers 6 and the rotary shaft 9 is extended below the autoclave 1 to be made rotatable through a rotary transmission shaft 10. Then, test pieces (a) are suspended from the disc by the upper chuck groups 13 arranged on the same circumference of the disc 7 at equal intervals and the specimen piece receiving disc 14 arranged below the disc 7 is supported and fixed by the lever 6 while a holder 15 is arranged so as to pierce through the disc at one suspension position among the groups 13. Further, a piercing body part 16 permitting the passage a part of each test piece (a) and engaging pieces 17, 17 are connected to the holder 15 in the rotary locus part of the test pieces (a) and each test piece (a) moved to the holder 15 by the disc 7 is enabled to be pulled by the pulling lever 18 provided to the lower end of the holder 15. |
