The Shore A hardness (durometer) scale is one of many durometer scales used to measure material hardness. Shore A durometers range from 0 to 100 — the higher the durometer value, the harder the material. . Manufacturers use durometer testing as a quality check for manufactured products. For example, silicone hardness or rubber hardness can .
Shore A Digital Hardness Meter Durometer 0~100HA, Rubber Tire Notes: A minimum thickness of 6mm as sample test probes is recommended for measurement's optimal results (if it's less you may add more layer but should not be more than 3 layers) and measuring point of at least 18mm distance from the outside edges The geometry of the indentor and the applied force influence the measurements such that no simple relationship exists between the measurements obtained with one type of durometer and those obtained with another type of durometer or other instruments used for measuring hardness. This test method is an empirical test intended primarily for . Durometer Shore hardness is the measure of how resistant materials, typically rubber, plastics, . Step 1: Choose the appropriate Shore hardness scale to measure the hardness of your test sample. Step 2: Place your test sample on a flat, horizontal, and hard surface that is at least ¼-inch thick.
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. It goes between 0 and 100. The higher number of hardness represents the harder material.The Shore hardness testers/durometers are used for determining the hardness of plastics and rubber according to standards ISO 48-4, ASTM D2240, ISO 868, NFT 51109 and BS 903 Part A26.For on-site testing on the product, analog versions with and without drag-pointer are available. The Shore hardness testers with drag pointers simplify testing, particularly in .

In the Shore hardness test, the indentation depth is measured using a spring-loaded indenter made of hardened steel to indent the material/specimen.The indentation depth is a measurement for Shore hardness, that is .It has a testing procedure for using it. It’s a specialized, self-referencing scale for comparing the hardness of a comparable group of materials. Note: Durometer Hardness measurements are unitless. This is the main reason comparing .
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 . Determining the hardness of a material can be done by using a durometer tester. In this video, we demonstrate how to use this device with different types of .
CCSi DuroMatters: Durometer Instrument Background. The material is generally termed “rubber or rubber—like”. 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. USA Testing Lab for ASTM D2240 Standard Test Method for Rubber Property-Durometer Hardness in USA, Indonesia, Philippines, Malaysia, Thailand, Canada, China, India, and all over the World. (302)244-7710 . . ASTM D618 for plastic conditioning, and ASTM D785 for testing the Rockwell hardness of plastic materials. Related. FAQ's.We should not compare hand-held durometers with a stand mounted Shore Hardness Tester. The hand-held durometer will check hardness, when used by a competent operator, and is perfectly valid form of first-line quality control. A stand mounted Shore Hardness Tester (which may or may not incorporate a durometer) will give a definitive hardness value.
Welcome to our ASTM D2240 testing services page for evaluating “Shore hardness” as part of our analysis of plastics and polymers.This standard, ASTM D2240, also known as “Rubber Property—Durometer Hardness,” allows for the measurement of a material’s hardness by indenting the material with a standardized tip under a defined force.
Durometer Hardness is used to determine the relative hardness of soft materials, usually plastic or rubber. The test measures the penetration of a specified indentor into the material under specified conditions of force and time. The hardness value is often used to identify or specify a particular hardness of elastomers or as a quality control .
The Shore D hardness scale is a test method that determines the hardness of a material. Learn more about it here. . is a method and reference system for measuring the hardness of materials such as rubber and plastic with a tool called a durometer. The exact measurement points to how much force a material can handle before an indent is created. The Shore hardness scale that should be used depends on the test specimen material, while the shape and size of the indenting foot depend on the Shore hardness scale. Lay the test specimen on a hard, flat surface that is ¼” thick or greater. Test the Shore hardness of the material by placing the durometer and its indenting foot against the .
At Checkline.com, we strive to provide durometer hardness testers that will work, no matter what your testing environment is or what material you need to measure. We carry durometers that meet or exceed ASTM D-2240, DIN, ISO, and JIS standards. We offer Asker durometers as well as Shore A durometers, Shore D, and the rest of the Shore scale.Description of Technique. Durometer testing is used to determine the hardness of thermoplastic elastomers, vulcanized rubber, elastomeric materials, cellular materials, gel-like materials, and other plastics that are unsuitable for measurement by conventional Rockwell or microindentation hardness testing.Test the hardness of thin and irregularly shaped plastic, rubber, and laminate parts, such as O-rings. These testers can be used on products where the surface area is too small for accurate durometer readings with a standard Shore A tester, such as the rounded surface of O-rings. They include O-ring fixtures that hold five standard-sized O-rings in place during testing.
