what is a durometer material

The hardness of plastics is most commonly measured by the Shore® (Durometer) test or Rockwell hardness test. Both methods measure the resistance of plastics toward indentation and provide an empirical hardness value that doesn't necessarily correlate well to other properties or fundamental characteristics. Dr. Dmitri Kopeliovich Shore hardness is a measure of the resistance of a material to penetration of a spring loaded needle-like indenter. Hardness of Polymers (rubbers, plastics) is usually measured by Shore scales. Shore A scale is used for testing soft Elastomers (rubbers) and other soft polymers. Hardness of hard elastomers and most other polymer . A spring-loaded indenter (called a durometer) is pressed into the material sample, and the depth of penetration is converted to a hardness value. Rockwell hardness test, a type of hardness test . Each hardness testing method has a range of loads that are applicable to the use of the test. Some tests, like the Vickers hardness test, can be .

The values given in parentheses are for information only. 1.1 This test method describes a type of composite foam hardness measurement device known as durometer: Type CF. The procedure for determining indentation hardness of substances comprised of two or more elastomeric materials, .

F1957 Test Method for Composite Foam Hardness-Durometer Hardness 2.2 ISO Standard: 3 ISO/IEC 17025: 1999 General Requirements for the Com-petence of Testing and Calibration Laboratories 3. Summary of Test Method 3.1 This test method permits hardness measurements based on either initial indentation or indentation after a speciÞed period of time .ASTM D2240 durometers allow for a measurement of the initial hardness, or the indentation hardness after a given period of time. The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then .

Specifically, ASTM D2240 durometer hardness testing is restricted to thermoplastic elastomers, vulcanized (thermoset) rubber, elastomeric materials, cellular materials, and some plastics as defined by the ASTM Committee on Terminology in ASTM D1566. . Many hardness testing methods employ a technique that “permanently” deforms the material .The standard test method for measuring the durometer hardness of rubbers according to ASTM D2240–05 [6] is based on the penetration of a specified indenter forced into the material under specified conditions. The indentation hardness is inversely related to the penetration and is dependent on the elastic modulus and viscoelastic behavior of .

The Shore D hardness scale is a test method that determines the hardness of a material. Learn more about it here. . This is done with the pointed tip of a durometer, which presses into the surface of your material and is controlled by a spring with a force that you or the operator will set. The depth of the indent that the pointed steel rod .The ASTM D2240 standard actually recognizes twelve different Shore durometer scales for testing rubber hardness. The most common Shore durometer scales used are Shore OO, Shore A and Shore D. Shore OO measures extremely .Hardness testing within the realm of materials testing.
