ABSTRACT:
Brittleness of a coating substance such as a coating film that is too brittle and/or too thin to be independently removed or handled is rated on the basis of an outcome of detection of acoustic emissions which are produced when a test film piece prepared by laminating a support with the coating substance is deformed by a compression transverse test device and detected by an AE sensor attached to the test film.
