ASTM D determines the adhesion strength of rubber to rigid materials, such as metals. The standard requires that the testing machine conform to practices. This standard is issued under the fixed designation D ; the 1 These test methods are under the jurisdiction of ASTM Committee D11 on. This standard is issued under the fixed designation D ; the number These test methods are under the jurisdiction of ASTM Committee D11 on For.

They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. ASTM D determines the adhesion strength of rubber to rigid materials, such as metals. Once the test is aatm, you will want to record the force vs displacement. Line contact and special coated faces are also available.
Measuring adhesiveness with ASTM D Method C – PHOTOS | Hot Topics
Concrete, Asphalt and Rock. Before the aatm is applied, strip the rubber from the metal plate by using a sharp knife. Subscribe to Our Newsletters.
This geometry promotes interfacial failures. Although our engineers can provide guidance, we recommend you d49 the official ASTM D International Standard to achieve the best atm. Next Checking to see if you are a returning d49. The test engineer can learn more about the uniformity of the rubber coating from this visual monitoring. Onsite Training At Your Facility. XyLive is the best choice to enable the test engineer to visually monitor the progress of the test vs the data on the computer screen.
Maintaining unidirectional force throughout the process of peeling from a substrate. Email addresses can only contain letters, numbers and the following special characters: Method A describes a tension test used to determine the bond of a rubber part assembled between two parallel metal plates.
Next, mount the test specimens in the ast grips of the tensile test machine. The challenges of testing to this standard: Maintaining unidirectional force throughout the process of peeling from a substrate. The metal pieces are made with tabs on the backsides for gripping in the test machine. Repair Services and Parts.
ASTM D429 Rubber Property – Adhesion to Rigid Substrates
A shear test is done until a break occurs at a depth of 5 mm at the rubber-metal bond interface. Pneumatic asmt are active in that they maintain the same gripping force even as the specimen necks down. Method B describes a peel procedure to determine the adhesive strength between rubber materials to a metal plate or substrate.
The specimen for this method should be a strip of rubber 6. Next, place the specimen in the jaws attached to the fixed grip with the separating edge toward the operator. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test.
Most of the tests involve orthogonal tensile strength or peel strength of the adhesion interface. The assembly is cured in a degree Celcius oven for one hour. Each specimen will consist of a rubber puck with 2 pieces of metal. Our Series and Series universal testing systems meet this specification and provide an appropriate solution for this test application. Works very well with flat, thin specimens Eccentric design increases gripping force with tension.
WaveMatrix 2 for Dynamic Testing. We also recommend serrated jaws on your grips to avoid sample slipping. Glossary of Materials Testing Terms. Glossary of Materials Testing Terms. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Concrete, Asphalt and Rock. Test Method D helps determine the adhesive strength of rubber-to-metal bonding agents when the bond is formed after the rubber has been vulcanized.
Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Bluehill LE for Basic Testing. Load ratings from 1 kN to 10 kN lbf to 2, lbf Maximum specimen thicknesses of 7 mm or 8 mm 0. Place your specimens in the tensile test machines and pull to failure each test piece which remains sufficiently intact, including those exposed to the chosen environmental conditions and the control test pieces, and record the peak force required to do this.
The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common. Manual vice grips may also work but must be tightened very tight.
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.
