About Us Case Studies Blog Contact search Services Capabilities Expertise Industries Served Quality Durometer Testing Durometer testing is a physical test method that provides information on the hardness of rubber and plastic materials. Back to all Capabilities PRINT EMAIL About Durometer Testing There are several scales of Durometer, used for materials with different properties. The two most common scales, using slightly different measurement systems, are the A and D scales. The A scale is for softer plastics, while the D scale is for harder ones. However, the ASTM D2240 testing standard calls for a total of 12 scales, depending on the intended use with higher values indicating a harder material. Approaches SGS Polymer Solutions (SGS PSI) routinely uses the following durometer types: Shore A (softer plastics and most rubbers) Shore D (most plastics and harder rubbers) Shore M (microhardness for small samples) Shore O (highly elastic samples) Sample Considerations The sample considerations will vary depending upon which Shore Scale is being tested. All samples need to be solids. Common samples are: O-Rings Disks Bars of Materials Finished Products, like injection molded parts Contact us with your specific sample consideration questions.
