Next Checking to see if you are a returning visitor…. The ASTM D standard describes methods to perform these tests with deadweights as an alternative to using a test machine. Email addresses can only contain letters, numbers and the following special characters: 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.

Software for Series Systems. Once the test is complete, you will want to record the force vs displacement.

WaveMatrix 2 axtm Dynamic Testing. Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle. ASTM D test standard determines the adhesion of rubber to rigid metal substrates. 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 via vulcanizing. Vulcanizing is consists of a chemical reaction with sulfur and heating which improves the mechanical properties of rubber.

ASTM D429 Rubber Property – Adhesion to Rigid Substrates

Method A of ASTM D is used to determine atm values in instances where users feel this design is more reflective of an c429 product and where control tests have been set up as a result. 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 metal to rubber interfaces are convex. Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. Bluehill C429 Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Check this box to receive v429 commercial email from Instron focusing on products, upcoming events, and more!

Our Series and Series universal testing systems meet this specification and provide an appropriate solution ashm this test application. Some of the tests are aimed at shear strength of that adhesion interface. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: It is difficult to measure the data correctly and provide consistent results.

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. Record the total load at the time of failure. At the end of the test you will need to record the force vs displacement.

ASTM D Rubber Property – Adhesion to Rigid Substrates – Instron

Adjustable data acquisition rates allow the user to ensure they are capturing all the desired peaks and troughs throughout the entire test. Then subject the test pieces to the chosen environmental conditions.

Either the rubber material fails internally or at the adhesion surface to the metal. To begin testing, place the test specimen in the jaws attached to the fixed grip with the separating edge toward the operator. The dual – acting design of series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses. Onsite Training At Your Aatm.

We use cookies to improve your browsing experience. The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common. Glossary of Materials Testing Terms.

Repair Services and Parts. This geometry promotes interfacial failures.

They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.
