Method A describes a tension test used to determine the bond of a rubber part assembled between two parallel metal plates. Please confirm that you agree with our privacy and cookies policy to submit this form.
It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. The standard calls out several test d42 related to rubber adhesion strength; however, Methods A and B are the most common. Record the total load at the time qstm failure. Test Method C of ASTM D helps determine the adhesive strength of rubber-to-metal bonding agents when applied to conical or cone-shaped samples.
Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test.
This test is almost identical to Method B, except it applies exclusively to the rubber lining of a tank wall.
Method H is used for determining relative bond durability between adhesives with a quadruple shear test. Bluehill Astj Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Contact Us View Asgm Catalog. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.
As force is applied in one direction the material shrinks in the orthogonal direction. This will help avoid slipping in the test. Make sure that a 1 inch by 1 inch tab is kept from bonding by covering it with tape.
Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
The bonded area is 25mm by 25mm in astn middle of the metal piece. Create specimens that are 25 mm thick with a 29 mm diameter.
Measuring adhesiveness with ASTM D Method C – PHOTOS | Hot Topics
It is difficult to measure the data correctly and provide consistent results. Secrets of Reliable Testing. We also recommend serrated jaws on your grips to avoid sample slipping. Ast, to Instron News! 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. Pneumatic grips also provide constant clamping force throughout the test to avoid specimen slippage.
We highly recommend not using deadweights as those are asmt methods of retrieving data. The challenges of testing to this standard: Samples for Method A are cylinder assemblies consisting of a cylinder of rubber 3.
Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: How can we help you?
Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle. Email addresses can only contain letters, numbers and the following special characters: Apply the tension load at 2 inches per minute until the rubber either separates from the adhesive surface or until the rubber ruptures. 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 storage with a pre-strain.

They can be equipped with a selection of interchangeable grip jaw faces in various sizes and astn of surfaces including smooth ground, aztm and serrated.
Software for Series Systems. Next, mount the test specimens in the threaded grips c429 the tensile d49 machine. The dual – acting design of series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses. This ensures that the line of tensile force remains concentric with the grip body.
