Method of inspecting a honeycomb structural body for purifying exhaust gases and apparatus used in the method.

摘要

A method of inspecting an alternately sealed honeycomb structuralbody (1) is provided which can quickly, efficiently and accurately inspect presence of defects of the honeycomb structural body in a simple and economical manner. The method comprises flowing particulates in axial direction of the throughholes (2) from one end surface to the other end surface of the honeycomb structuralbodyy (1), catching the particulates on a gas-permeable screen (11) intimately mounted on the other end surface to form a pattern of the particulates, and checking the figure to inspect defects at internal partition walls and sealing portions of the honeycomb structural body(1). <IMAGE>
