ASTM D determines the adhesion strength of rubber to rigid materials, such as metals. The standard requires that the testing machine conform to practices. This standard is issued under the fixed designation D ; the 1 These test methods are under the jurisdiction of ASTM Committee D11 on. This standard is issued under the fixed designation D ; the number These test methods are under the jurisdiction of ASTM Committee D11 on For.

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

E429 LE for Basic Testing. Create specimens that are 25 mm thick with a 29 mm diameter. Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. Concrete, Asphalt and Rock. Then subject the test pieces to the chosen environmental conditions. The dual – acting design of series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses.

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

ASTM D429 Rubber Property – Adhesion to Rigid Substrates

Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: The specimen for this method should be a strip of f429 6. This test is often used to find which adhesive is best for the given rubber. Contact Us View Accessories Catalog. Samples for Method A are cylinder assemblies consisting of a cylinder of rubber 3.


ASTM D429 Rubber to Metal Adhesion Test Equipment

This ensures that the line of tensile force remains concentric with the grip body. Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test.

Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle. Vulcanizing is consists of a chemical reaction with sulfur and heating which improves the mechanical properties of rubber.

The sample also lends itself to testing the effectiveness of different processing techniques and various adhesive systems. Make sure that a 1 inch by 1 inch tab is kept from bonding by covering it with 4d29. Our Series and Series universal testing systems meet this specification and provide an appropriate solution for this test application. Software for Series Systems. Software for Series Systems. Email addresses can only contain letters, numbers and the following special characters: 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.

The standard calls out several test types related to rubber adhesion strength; however, Methods A asym B are the most common. This test standard is divided into methods A through H.

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 metal to rubber interfaces are convex.


Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. How can astj help you?

This geometry promotes interfacial failures. Data from this test will be a typical tensile force plot force vs displacement. How can we help you? The value of interest is the “Adhesion Strength” defined as the maximum force divided by the width of the specimen.

By continuing to use our site, you accept our cookie d492. We highly recommend not using deadweights as those are outdated c429 of retrieving data. Once the samples have cooled, clamp the bonded assembly to the tension testing machine using tensile grips.

The upper and lower parts of the specimen are metal cones with slots or threads for connecting to the tensile test machine. Either the rubber material fails internally or at the adhesion surface to the metal.

The strip is volcanized to a piece of metal which is 1.

Record the total force at the time of failure. Bluehill LE for Basic Testing. Next Checking to see if you awtm a returning visitor…. Clamp force up to 1. We use cookies to improve your browsing experience. Method G of ASTM D measures the bond strength of rubber to metal components with a double shear cylindrical d49. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.
