ISO 813 Adhesion Strength of Rubber to Rigid Substrates
ISO 813 specifies a method for the determination of the adhesive strength of rubber to rigid materials. The standard describes a peel procedure to determine the adhesive strength between rubber materials to a rigid substrate. In an adhesion test, a measured forced is applied to a test specimen in order to strip a layer from the specimen with tearing at the bonded surfaces. The value of interest is the "Adhesion Strength" - defined as the maximum force divided by the width of the specimen. Data acquisition is a key factor in obtaining accurate test results. The sampling rate of the testing system should be high enough to accurately capture the test peaks and troughs.
Bluehill® Software calculates the adhesion value and allows the operator to register the observed failure type from a drop-down menu that increases productivity and facilitates opearors training. We recommend a 90° peel fixture that holds and moves the substrate as the rubber strip is peeled off by an upper grip. Pneumatic side-action grips provide an appropriate solution due to ease of use, productivity and improved repeatability. Manual screw-action grips also provide an adequate and affordable solution for this test.

Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. The dual - acting design of 2710-100 series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses. This ensures that the line of tensile force remains concentric with the grip body. They can be equipped with a selection of interchangeable grip jaw faces in various sizes and choice of surfaces including smooth ground, rubber-coated and serrated. Line contact and special coated faces are also available.The unique ‘snap-on’ jaw face attachment makes changing faces extremely quick and simple.
