PURPOSE:To make it possible to perform the material test of many test pieces simultaneously, by providing a load detecting means and a driving means, which are linked to the load side in series, and providing only a test-piece holding part in an atmospheric chamber under the closely sealed state so that the holding part can be attached and detached. CONSTITUTION:A chamber 14 is formed in a box shape by an upper surface plate, a lower surface plate, a supporting plate and side surface plates. An atmospheric space is formed by the adjustment of inner temperature and humidity, sealing of a special gas and the like. A test piece 20 is held between a first rod 12 and a second rod 17. Then the lower prt of an upper frame 11 is inserted into the hole part of the upper surface plate of the chamber 14 and fixed. Thus plurality of test pieces can be tested in various kinds of atmospheres simultaneously without deteriorating the part on the load side. |
