ASTM D determines the adhesion strength of rubber to rigid materials, such as metals.

ASTM D429 Rubber Property – Adhesion to Rigid Substrates

The durable, hard chrome finish resists the corrosive and adhesive effects of most compounds, greatly improving overall durability asstm ease of maintenance. Awtm B describes a peel procedure to determine the adhesive strength between rubber materials to a metal plate or substrate. Once the test is complete, you will want to record the force vs displacement. Each puck should be. In the Figure 7 diagram, the specimen is shown in a horizontal position, when in reality, the specimen would be placed vertically in the test machine.

Prepare the rubber specimen astmm this test by vulcanizing it to the metal material of the tank. This test standard is divided into methods A through H. Rubber is typically bonded to metal during the vulcanizing or heating process, but this method is for glue or other materials that are used after the rubber is made via vulcanizing. Have a question about conducting the test for this standard?

Record the total force at the time of failure. As force is applied in one direction the material shrinks in the orthogonal direction. 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.

The test engineer can learn more about the uniformity of the astk coating from this visual monitoring. Make sure that a 1 inch by axtm inch tab is kept from bonding by covering it with tape. Test Method A helps determine the static adhesion strength of rubber to metal. It is difficult to measure the data correctly and provide consistent results. Mount the vulcanized standard test specimen in the tensile testing machine using care in centering and adjustment so that the tension shall be uniformly distributed.

Some of the tests are aimed at shear strength of that adhesion interface.

ASTM D – 14 Standard Test Methods for Rubber Property—Adhesion to Rigid Substrates

Next, place the specimen in the jaws attached to the fixed grip with the separating edge toward the operator. This ensures that the line of tensile force remains concentric with the grip body.

By continuing to use our site, you accept our cookie policy. Next, the test pieces should be pre-strained by pulling in a test machine to just above the desired pre-strain and inserting a nylon block between the central metal plates to maintain the prescribed prestrain. 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.

Our Universal Testing Systems meet this specification and provide an appropriate solution for this test application. Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle.

ASTM D429 – 14

The test machine should be equipped with swivel joints above and below asym ensure uniformly distributed tensile force tensile force through the specimen assembly. At the end of the test you will need to record the force vs displacement. This test combines tensile and shear forces in the rubber specimen material.

These further facilitate mold opening and reduce the occurrence of cavity damage from improperly positioned tools. Place the tab in the grip and apply a steady load at a test speed of 50 mm 2.

Astj the total load at the time of failure. We are confident that we have what you are looking for. Create specimens that are 25 mm thick with a 29 mm diameter.

The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common. The results are obtained by measuring the force necessary to separate a rubber from a metal surface. 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.

Test Method C of ASTM D helps determine d42 adhesive strength of rubber-to-metal bonding agents when applied to conical or cone-shaped samples.
