what is a durometer material
Durometer is a metric used to quantify the hardness or resistance to indentation of materials. It provides a numerical value that indicates the material’s ability to withstand deformation under an applied force.

One of our specialists will email you an RMA number and instructions to send in your unit. Turn around time is usually 3 to 5 days from the date it arrives at PTC Metrology . Our sales department (310-478-1134) will help you determine the correct durometer for your hardness test. We offer material testing to determine the correct durometer .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.
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.A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.
Shore Hardness Test Stand NOVOTEST is very useful for measurements with Shore durometers. In the most cases using Shore Durometer with stand is the optimal choice, because of the operator’s errors during measurements are much decreased, and lets to get more accurate result. The unit has simple design and high-quality parts.View Shore Durometer Hardness Scale Infographic. Type A Durometers are designed for measuring medium-soft to medium-hard materials such as softer plastics and rubbers (under 50 Shore Hardness Units) often used in power cord insulation and vinyl shoe soles, but have the capacity to measure materials as resistant as solid truck tires and ebonite rubber (up to 100 .Test Shore hardness of rubber and plastics. A Durometer is a material hardness tester for rubber, elastomer, plastic and other similar compounds. They use a specific spring force and indenter shape combination to measure the indentation depth created and the corresponding resistance, according to the ASTM D2240 test standard.

Ceramics. Elastomers. Polymers and plastics. Films. Rocks and minerals. Importance of Hardness .
To take a measurement, the durometer’s base is pressed evenly (via hand or using the test stand) against the test material, which also forces the indenter into it. The material’s resistance to the indenter in turn pushes it back . In a significant leap forward for the rubber testing industry, Qualitest in collaboration with Gibitre proudly announces the launch of the latest innovation, the Digital Shore Durometer Hardness Tester – DRIVE Series, available in Shore A, D, DO, and OO scales.
