The Buchholz Indentation Tester is a reliable test method for evaluating the indentation resistance of plastic's deformable coatings. A beveled disc with a sharp edge is applied onto the test surface under a constant of 1.1lbs (500g). The test load is provided by a steel block holder. The trace left after 30s. load is measured with a 20X magnification illuminated microscope. The length of the indentation is inversely proportional to the hardness.
