ASTM D429 Rubber Property - Adhesion to Rigid Substrates
ASTM D429 determines the adhesion strength of rubber to rigid materials, such as metals. The standard requires that the testing machine conform to practices described in ASTM E4. Our 3400 and 6800 Series universal testing systems meet this specification and provide an appropriate solution for this test application.
The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common.
- Method A describes a tension test used to determine the bond of a rubber part assembled between two parallel metal plates.
- Method B describes a peel procedure to determine the adhesive strength between rubber materials to a metal plate or substrate. The value of interest is the "Adhesion Strength" defined as the maximum force divided by the width of the specimen.
The challenges of testing to this standard:
- Accurately tracking the peaks and troughs throughout the adhesion test in order to report precise results.
- Maintaining unidirectional force throughout the process of peeling from a substrate.
- Proper specimen gripping.
Our solutions:
- Bluehill Universal® software can calculate adhesion strength values per this test method. Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test. (Methods A and B)
- We recommend using a specialized fixture that holds and moves the substrate as the rubber strip is peeled off by an upper grip. (Methods B)
It is important to review ASTM D429 in order to fully understand the test setup, procedure, and results requirements.

2710 Series Screw Side Action Grips
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.
