Gurley Stiffness Tester STD-AG84


Application

The Gurley Stiffness Testeris based on the Gurley Softness Tester test method. It applies a certain mechanical external force to the sample and measures its deformation to obtain the bending resistance or stiffness of the material.

The Gurley Stiffness Tester is used to measure the bending resistance (stiffness) of materials such as paper, cardboard, fabric, non-woven fabric, and artificial leather, especially for relatively stiff fabrics.
