Organization: ASTM International: Publication Date: 15 June 2021: Status: active: Page Count: 13: ICS Code (Rubber): 83.060: The ASTM D2240 standard outlines the test procedure for measuring the hardness of elastomers using a durometer. The test involves measuring the depth of penetration of a specific indentor into the material under specific conditions of force and time. . The durometer hardness test results are reported in either Shore A or Shore D scales .
The indentation hardness is then determined based on the elastic modulus and viscoelastic behavior of the sample. Test Details The ASTM D2240 test method is used to evaluate the hardness of the following types of rubber materials: thermoplastic elastomers, vulcanized rubber, elastomeric materials, and some types of plastics.The Shore D Hardness test is also called Durometer Hardness Test. The letter "D" symbolizes the type of durometer used to measure the hardness of a material. It is a dimensionless quantity. . The test methods used to measure Shore D Hardness are: ASTM D2240 and ; ISO 868; What is the difference between Shore D and Shore A hardness? Type D: .Thicker coatings are typically measured using an indentor-type tester such as a Durometer (ASTM D2240, Standard Test Method for Rubber Property – Durometer Hardness), which measures the resistance to indentation under a specific spring force load. The project specification should indicate the appropriate type of hardness testing (Pencil or .
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 . This test method is not equivalent to other indentation hardness methods and instrument types, specifically those described in Test Method D1415. This test method is not applicable to the testing of coated fabrics.

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 .A durometer is an instrument for testing the hardness of various plastics & rubber. ASTM D2240 Standard Test Method for Rubber Property, Durometer Hardness. This test method covers twelve types of rubber hardness measurement devices known as durometers.The ASTM standardized the testing procedures and scales for measuring the hardness of rubber materials using the Shore durometer. As a result, the Shore durometer became widely adopted and recognized as the industry standard for rubber hardness measurement. . Durometer testing measures the hardness at the material’s surface. It may not . 5.1 This method is based on the penetration of a specific type of indentor when forced into the material under specified conditions. The indentation hardness is inversely related to the penetration and is dependent on the elastic modulus, viscoelastic behavior of the material, geometry of the indentor, the applied force and temperature at test.
Shore (Durometer) Testing. The Shore (Durometer) test is the preferred hardness testing method for elastomers and is also commonly used for compliant plastics such as polyolefins, fluoropolymers, and vinyl polymers. Shore hardness testing is typically performed following ASTM [19] standards. The two most common test procedures are the Shore A .
