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.

The standard calls out several test types related asrm rubber adhesion strength; however, Methods A and B are the most common. Rubber is typically bonded to metal during the vulcanizing or heating process, but this method is for glue or other materials that are used after the rubber is made d42 vulcanizing. 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.
ASTM D Rubber to Metal Adhesion Test Equipment
Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test. Some of the tests are aimed at shear strength of that adhesion interface. Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle.
Samples for Method A are cylinder assemblies consisting of a cylinder of rubber 3. Subscribe to Instron News! The metal pieces are made with tabs on the backsides for gripping in the test machine.
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 metal to rubber interfaces are convex.
Concrete, Asphalt and Rock. Method G of ASTM D measures the bond strength of rubber to metal components with a double shear cylindrical specimen.
Line contact and d492 coated faces are also available. Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test. Give one of our engineers a call today and they can help guide you through the ASTM D test process with the best machine configuration for your requirements. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest v429 of Bluehill.
The strip is volcanized to a piece of metal which is 1. Make sure that a 1 inch by 1 inch tab is kept from bonding by covering it with tape.
Next Checking to see if you are a returning visitor…. ASTM D test standard determines the adhesion of rubber to rigid metal substrates. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.
Contact Us View Accessories Catalog. The specimen for this method should be a strip of rubber 6. The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common. Subscribe to Our Newsletters. Email addresses can only contain letters, numbers and the following special characters: The grips for holding the specimen in the testing machine depend on the type of specimen. This geometry promotes interfacial failures. Peel fixtures provide a condition of use to measure astn bond strength between laminated surface coatings, films, packaging, and their rigid backings, as well as other bonded structures.
Load ratings from 1 kN to 10 kN lbf to 2, lbf Maximum specimen thicknesses of 7 mm or 8 mm 0. Each specimen will consist of a rubber puck with 2 pieces of metal. The dual – acting design of series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses.
Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. As force is applied in d4299 direction the material shrinks in the orthogonal direction.

Manual vice grips may also work but must be tightened very tight. The adhesion values are obtained by measuring the force in an axial direction that is necessary to separate the bonded rubber from the metal component.
Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.
To prepare the specimens for Method D, 6 rubber pucks are mounted in an assembly awtm a clamp to hold compressive force.
