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… SpletNominal Shore D Durometer Hardness 0 10 2 30 4 50 6 70 8 90 100 Comparison of Young’s Modulus to Shore D Durometer y = 11.31e0.0645x 10 1 0.1 0.01 Y oung ’s Modulus, MPa Nominal Shore OO Durometer Hardness 0 10 20 30 40 50 60 70 80 90 Young’s Modulus Comparison to Shore OO Durometer y = 0.0037e0.0718x 1-25% Secant RDA Qi Equation …

Shore A Versus Shore D: The Important Differences You …
SpletThe Hardness of elastomer O Rings is measured by the Shore A durometer mentioned above. The higher the durometer, the harder the material. Commonly, 70-durometer … SpletThe Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or tungsten ball subjected to a load of 3000 kg. For softer materials, there are alternate scales using a 1500 kg or 500 … SpletA hardness of Shore D applies to harder elastomers or plastic materials. The tester for this range has a pointed tip. If values below 20 D are read, the Shore A hardness tester should be used. Plasticizer-free Desmopan® can be obtained in a hardness range of 60 Shore A to 75 Shore D. ...
