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.
The durometer apparatus measures the deflection of a calibrated spring as an indenter is pressed into the sample either manually (by hand) or using an operating stand. The indenter protrudes from an orifice in a presser foot, which ensures consistent and repeatable contact between the durometer apparatus and the sample surface.
The twelve standard durometer scales (A, B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R) are defined by their presser foot geometry, indenter tip shape, and spring force. MEE offers testing for a wide range of materials by using two of the most common durometer types, A and D, as well as the type M micro-hardness durometer.
