It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.

ASTM D determines the adhesion strength of rubber to rigid materials, such as metals. Data from this test will be a typical tensile force plot force vs displacement.

Measuring adhesiveness with ASTM D Method C – PHOTOS | Hot Topics

Samples for Method A are cylinder assemblies consisting of a cylinder of rubber 3. Maintaining unidirectional force throughout the process of peeling from a substrate.

The results are obtained by measuring the force necessary to separate a rubber from astk metal surface. Next Checking to see if you are a returning visitor….

Line contact and special coated faces are also available. Concrete, Asphalt and Rock. The test machine should be equipped with swivel joints above and below to ensure uniformly distributed tensile force tensile force through the specimen assembly. The metal to rubber interfaces are convex. 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.

This test is almost identical f429 Method B, except it applies exclusively to the rubber lining of a tank wall. The dd429 of the specimen is rubber which bonds the two cones together.


Case Studies

Make sure that a 1 inch by 1 inch tab is kept from bonding by covering it with tape. Some of the tests are aimed at shear strength of that adhesion interface. Next, take the assembly out of the oven and take it apart to create six test specimens.

The specimens are placed into the shear test fixture and the shear stress is placed on the bond line. Before the load is applied, strip the rubber from the metal plate by atm a sharp knife.

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

The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common. Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. Have a question about conducting the test for this standard? It may apply to vibratory or vibration applications, although this test is not adtm. Slippage in grips will be a big challenge in testing rubber coating of metal because coating adhesion must be strong but rubber material necks down, also called Poisson effect.

Our Series and Series universal testing systems meet this specification and provide an appropriate solution for this test application.

Method B describes a peel procedure to determine the adhesive strength between rubber materials to a metal plate or substrate. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.


The sample also lends itself to testing the effectiveness of different processing techniques and various adhesive systems. Method A describes a tension test used to determine the bond of a rubber part assembled between two parallel metal plates. Peel fixtures provide a condition of use to measure the bond strength between laminated surface coatings, films, packaging, and their rigid backings, as well as other bonded structures.

Apply the tension load at 2 inches per minute until the rubber either separates from the adhesive surface or until the rubber ruptures.

axtm This test standard is divided into methods A through H. Glossary of Materials Testing Terms. The upper and lower parts of the specimen are metal cones with slots or threads for connecting to the tensile test machine. Method B of ASTM D is intended to determine the adhesive strength of rubber to metal bonding agents by 90 degree peel strip test.

Pneumatic grips are active in that they maintain the same gripping force even as the specimen necks down. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!

Loads as high at 10, pounds can be common. By continuing to use our site, you accept our cookie policy. We are confident that we have what you are looking for. Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test.
