Method B describes a peel procedure to determine the adhesive strength between rubber materials to a metal plate or substrate. ASTM D determines the adhesion strength of rubber to rigid materials, such as metals. Next Checking to see if you are a returning visitor…. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.
Load ratings from 1 kN to 10 kN lbf to 2, lbf Maximum specimen thicknesses of 7 mm or 8 mm 0. Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications.
We are confident that we have what you are looking for. 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.
ASTM D429 Rubber Property – Adhesion to Rigid Substrates
It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. Email addresses can only contain letters, numbers and the following special characters: This test combines tensile and shear forces in the rubber specimen material. Glossary of Materials Testing Terms. Record the total force at the time of failure. The test is an orthogonal tensile test where the puck is pulled apart in tension. This section will be used to clamp in the jaws of the grip.
The strip is volcanized to a piece of metal which is 1.
The standard calls out several test types related to rubber adhesion strength; however, Asmt A and B are the most common. 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. It may apply to vibratory or vibration applications, although this test is not dynamic. Peel force is indicated in pounds per square inch of length of the peel line.
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. The assembly is cured in a degree Celcius oven for one hour.
Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Next, the test pieces should be pre-strained by pulling in a test machine to just above the desired pre-strain and inserting atm nylon block between the central metal plates to maintain the prescribed prestrain.
Secrets of Reliable Testing. Software for Series Systems.
Method A of ASTM D is used to determine adhesion values in instances where users feel this design is more reflective of an actual product and where control tests have been set up as a result. Method G of ASTM D measures the bond strength of rubber to metal components with a double shear cylindrical specimen.
The bonded area is 25mm by 25mm in the middle of the metal piece. Samples for Method A are cylinder assemblies consisting of a cylinder of rubber 3.
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. Loads as high at 10, pounds can be common.
Each puck should be. The upper and lower parts of the specimen are metal cones with slots or threads for connecting to the tensile test machine. 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 value of interest is the “Adhesion Strength” defined as the maximum force divided by the width of the specimen. Once the samples have cooled, clamp the bonded assembly to the tension testing machine using tensile grips.
First, pull a quality control test piece from each molded batch to determine that per cent adhesion is obtained prior aztm environmental exposure or laboratory storage with a pre-strain. Place your specimens in the tensile test machines and pull to failure each test piece which remains sufficiently intact, including those exposed to asfm chosen environmental conditions and the control test pieces, and record the peak force required to do this.

Measuring adhesiveness with ASTM D Method C – PHOTOS | Hot Topics
Clamp force up to 1. The results are obtained by measuring the force necessary to separate a rubber from a metal surface. Contact Us View Accessories Catalog.
Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle. R429 will help avoid slipping in the test. Concrete, Asphalt and Rock.
