When it comes to plastic hardness testing, the most commonly used test is the Shore D test. The Shore D test uses a type D durometer, such as NextGen’s Advanced Portable Shore Durometer System – designed to measure the hardness of many plastics.

The Shore D test method applies a standardized force to the surface of the plastic. It measures the depth of the indentation, which is then reported on a scale ranging from 0 to 100, with higher numbers indicating a harder material. The Shore D test is widely used in various industries, including automotive, aerospace, and construction, to evaluate the performance and durability of plastic products.

Not all plastics can be tested with the Shore D test, as some plastics may be too soft or too flexible to be accurately measured with this method. In these cases, alternative methods, such as the Rockwell hardness test or the Barcol hardness test, may be used to determine the hardness of the plastic. The choice of test method depends on the type of plastic, its thickness, and other factors and should be determined based on the relevant industry standards and specifications.
