Abstract
An apparatus and method for testing the mechanical durability of a test surface finish of an object, such as a cooking vessel. The apparatus consists principally of a sliding support fixture operated by a gearmotor with an eccentric drive providing alternative forward and rearward movement to the fixture, scrapers for contacting the surface finish in a predetermined path, and individually operated coil springs for applying constant pressure to the scrapers during the test scraping cycle. A cam and lever combination is also supplied to raise the scrapers above the surface finish as they are returned to initial start position during cyclical test operation.
