Abstract

PURPOSE:To make possible the evaluation of the cleanliness of the layer right under the surface of the material to be tested by arbitrarily adjustably reproducing ironing rate. CONSTITUTION:A lower clamping jig piece 10' opposing to an upper clamping jig piece 10 fixed to the upper plate 8 of a testing machine base rod 6 is mounted to the hydraulic cylinder device 11 equipped to a base plate 7, and multiple kinds of ironing jigs 12 each provided with a shoulder part for ironing consisting of a curved face of a prescribed radius dr are prepared and are made freely attachable and datachable to and from the upper plate 8 by means of bolts 13. Then, if the ironing jig 12 provided with the ironing curved face corresponding to actual drawing is mounted to the upper plate 8 and the gripping strength of a pair of the clamping jigs 10, 10' for gripping the end part of the material 15 to be tested is adjusted by regulating the pressure of the device 11, the pulling force for the material 15 is set arbitrarily by this, and the drawing state accompanying ironing is reproduced, whereby the intended object is achieved.
