Abstract

PURPOSE:To perform the impact test of the coated film quickly and positively by providing a plurality of chip guides and holding chips at a desired heights. CONSTITUTION:Test pieces 1... on the surface of which the coated film is formed are mounted at the location including impact point 4, to which the chips 5 fall, on an inclined surface 2a of a receiving table 2 by a supporting member 3. On the upper part of said surface 2a, tubular chip guides 6... which guide the fall of the chips 5 and have desired lengths are provided so as to face the test piece 1 by a holder 7. The chips 5 are held at the desired heights by the excitation of electromagnets 11. When these electromagnets 11... are demagnetized, the chips having the desired weights at the desired heights fall, and the impact test by a plurality of the test pieces can be concurrently performed. Therefore, the impact test of the coating film can be performed quickly and positively.
