How can we help you? The sample also lends itself to testing the effectiveness of different processing techniques and various adhesive systems. 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. Once the samples have cooled, clamp the bonded assembly to the tension testing machine using tensile grips. Some of the tests are aimed at shear strength of that adhesion interface.

aetm Please confirm that you agree with our privacy and cookies policy to submit this form. The data obtained indicate the strength of adhesion along a line across the ast, of the rubber strip being separated from a metal plate at a 90 degree angle.

The challenges of testing to this standard: The challenges of testing to this standard: Method H is used for determining relative bond durability between adhesives with a quadruple shear test. To begin testing, place the test specimen in the jaws attached to the fixed grip with the separating edge toward the operator. Peel fixtures provide a condition of use to measure the bond strength between laminated surface coatings, films, packaging, and their rigid backings, as 4d29 as other bonded structures.

Email addresses must contain the symbol. Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test.

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. Samples for Method A are cylinder assemblies consisting of a ast, of rubber 3. Subscribe to Our Newsletters. Apply a steady tension load until the rubber awtm separates from the metal surface or ruptures.

ASTM D Rubber to Metal Adhesion Test Equipment

The bonded area ast, 25mm by 25mm in the middle of the metal piece. This test standard is divided into methods A through H. Common application examples that use tests in ASTM D are vehicle engine mounts, vehicle suspension bushings, rubber-coated metal parts, and rubber-lined tanks and containers.

Repair Services and Parts.

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

Case Studies

Each specimen will consist of a rubber puck with 2 pieces of metal. WaveMatrix 2 for Dynamic Testing. Make sure that a 1 inch by 1 inch tab is kept from bonding by covering it with tape.

Method B describes a peel procedure to determine the adhesive strength between rubber materials to a metal plate or substrate. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle.

To prepare the specimens for Method D, 6 rubber pucks are mounted in an assembly with a clamp to hold compressive force.

This ensures that the line of tensile force remains concentric with the grip body. We also recommend serrated jaws on your grips to avoid sample slipping. Next Checking to see if you are a returning visitor…. Peel fixtures provide a condition of use to measure the bond strength between laminated surface astj, films, packaging, and their rigid backings, as well as other bonded structures.

The assembly is cured in a degree Celcius oven for one hour. 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.

Software for Series Systems. 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 grips for holding the specimen in the testing machine depend on xstm type of specimen. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. This test is almost identical to Method B, except it applies exclusively xstm the rubber lining of a tank wall. We use cookies to improve your browsing experience.
