ASTM D Rubber to Metal Adhesion Test Equipment

This ensures that the line of tensile force remains concentric with the grip body. Pneumatic grips are active in that they maintain the same gripping force even as the specimen necks down.

Next Checking to see if you are a returning visitor…. 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. Before the load is applied, strip the rubber from the metal plate by using a sharp knife.

We use cookies to improve your browsing experience. The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common.

Glossary of Materials Testing Terms. This test combines tensile and shear forces in the rubber specimen material. To prepare the specimens for Method D, 6 rubber pucks are mounted in an assembly with a clamp to hold compressive force.

WaveMatrix 2 for Dynamic Testing. 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. Secrets of Reliable Testing.

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

The sample also lends itself to testing the effectiveness of different processing techniques and various adhesive systems. Please confirm that you agree with our privacy and cookies policy to submit this form.

First, pull a quality control test piece from each molded batch to determine that per cent adhesion is obtained prior to environmental exposure or laboratory asstm with a pre-strain. The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common.

The metal pieces are made with tabs on the backsides for gripping in the test machine. Method A describes a tension test used to determine the bond of a rubber part assembled between two parallel metal plates. Have a question about conducting the test for this standard? Method A describes a tension test used to determine the bond of a rubber part assembled between two parallel metal plates.

At the end of the test you will need to record the force vs displacement.

Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.

Glossary of Materials Testing Terms. Line contact and special coated faces are also available. The bonded area is 25mm by 25mm in the middle of the metal piece. Manual vice grips may also work but must be tightened very tight. We are confident that we have what you are looking for. The challenges of testing to this standard: Screw side-action grips provide a very simple and efficient method for holding test specimens in asfm wide range of applications.

Once the test is complete, you will want to record the force vs displacement. ASTM D determines the adhesion strength of rubber to rigid materials, such as metals.

ASTM D test standard determines the adhesion of rubber to rigid metal substrates. To begin testing, place the test specimen in the jaws attached to the fixed grip with the separating edge toward the operator. The dual – acting design of series grips means that jaw faces can be adjusted to aatm different specimen thicknesses.

Case Studies

Users of previous versions ast software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. The middle of the specimen is rubber which bonds the two cones together.

Bluehill LE for Basic Testing. It is difficult to measure the data correctly and provide consistent results.
