Rockwell hardness is the most commonly used method for measuring the hardness of plastics.
Rockwell hardness is a type of indentation hardness that incorporates creep behavior into hardness measurement, taking into account properties such as elastic modulus and recoverability. There are three scales: R, L, and M, with the R scale being the most commonly compared in catalogs, followed by the M scale. The standard specifies an appropriate range of 50 to 115, and it is noted that if the measurement exceeds 100, it is advisable to measure using the next harder scale. For values below HRR50, Rockwell hardness is deemed inappropriate, and it is preferable to choose durometer hardness instead.
