    Abstract

    While establishing performance specifications for building elements, the authors have recognized the fact that there is no available test method for the direct investigation of scratch resistance of thick wall coverings. This has led to the development and manufacture of a prototype scratch-test instrument. Verification tests have been carried out on 18 types of laboratory samples and three existing walls. The research included investigation of repeatability of results, influence of speed of operation, influence of operator, performance fitness, and accuracy of results. Finally grading of the “degree of damage,” according to the depth of scratch has been deduced. Acceptance criteria for different functional uses are suggested.
