PROBLEM TO BE SOLVED: To set test pieces stably by positioning a plurality of the test pieces on a rectangular tray, arranging the test pieces in orderly sequence and mounting the test pieces and to enable measurement of hardness and thickness and transmission of testing conditions with the test pieces being mounted. ;SOLUTION: A plurality of test pieces 1 are mounted in the direction intersecting the feeding direction of a rectangular test-piece tray 2. Respective curve parts 1A at four parts are placed against protruding parts 5, and the positions are determined. Even the test piece 1 having the expansion and contraction of about 10% from treatment for oil resistance, aging and the like is positioned always constantly by the curved part 1A in contact with the protruding part 5. Since the tray 2 is in a pallet shape, there are no extrusion and the gap of the test piece 1, and the test piece can be fed to a tensile tester. When the tray 2 is inserted into a test-piece feeding device, the position of the original point of the tray 2 is detected with a detecting hole 7. Furthermore, with the test piece being mounted on the tray 2, the thickness measurement and the hardness detection of the test piece 1 can be performed through a pulling hole 8 and a through hole 9. Furthermore, the test conditions can be transmitted and supplied by means of a bar code label 6.;COPYRIGHT: (C)1997,JPO
