Web14 apr. 2024 · Shore A Scale. The Shore A scale ranges from 0A to 100A. 0A durometer molded parts would be very soft, while parts made using 100A duro rubber would be very hard. We typically deal with molded products that range from 20A (similar to the hardness of rubber bands) - 80A (rubbers similar in hardness to what you'd find on a shoe's heel), … Durometer, like many other hardness tests, measures the depth of an indentation in the material created by a given force on a standardized presser foot. This depth is dependent on the hardness of the material, its viscoelastic properties, the shape of the presser foot, and the duration of the test. ASTM D2240 durometers allows for a measurement of the initial hardness, or the ind…

Web2 Pendulum Damping - A Measure for Flexibility. The pendulum test is often incorrectly referred to as a hardness test although it assesses the elastic and visco-elastic behavior of a coating. In this test, the oscillation amplitude of a pendulum is evaluated. The pendulum rests on the coating surface with two balls and is set into oscillation.

Webtest: the Rockwell hardness test and the Rockwell superficial hardness test. The significant difference between the two test classifications is in the test forces that are used. For the Rockwell hardness test, the preliminary test force is 10 kgf (98 N) and the total test forces are 60 kgf (589 N), 100 kgf (981 N), and 150 kgf (1471 N).
