A material’s resistance to abrasion can be measured using a variety of standard test methods and abrading materials in a controlled process and environment, including ASTM, DIN, ISO and JIS methods. For more precise measurements, TABER recommends an Optical Micrometer. The scratch resistance of the test piece is the smallest weight force which leaves a continuous scratch on the test field. Due to the difficulty in cutting grooves of identical width, minor deviations can be compensated for by averaging the measurements. An electronic timer displays the rate of speed, which can be controlled by reducing or increasing air pressure. Optional weights sets are also available consisting of either 4N, 8N, 9N, 12N or 8N, 13N, 18N weights.
