Secrets of Reliable Testing. Software for Series Systems. The ASTM D standard describes methods to perform these tests with deadweights 4d29 an alternative to using a test machine. Our engineers are familiar with ASTM D and can help guide you through the testing process with the proper equipment.

It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. Pneumatic grips also provide constant clamping force throughout the test to avoid specimen slippage.

Make sure that a 1 inch by 1 inch asttm is kept from bonding by covering it with tape. Slippage in grips will be a s429 challenge in testing rubber coating of metal because coating adhesion must be strong but rubber material necks down, also called Poisson effect. Although our engineers can provide guidance, we recommend you purchase the official ASTM D International Standard to achieve the best results.

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. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.

They are designed with standard and optional features that increase testing efficiency and improve the axtm experience for the operator. This will help avoid slipping in the test. Concrete, Asphalt and Rock. Manual vice grips may also work but must be tightened very tight. V429 Series astmm Series universal testing systems meet this specification and provide an appropriate solution for this test application. The standard calls out several test types related to rubber adhesion strength; however, Methods A and B are the most common.

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. Before the load is applied, strip the rubber from the metal plate by using a sharp knife. Place the tab in the grip and apply a steady load at the rate of 50 mm 2. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

This test machine is suggested because it has a long travel, which is preferred because rubber coating tests to enlongate quite a bit when stretched. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. WaveMatrix 2 for Dynamic Testing. 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. Line contact and special coated faces are also available.

The bonded area is 25mm by 25mm in the middle of the metal piece.

Case Studies

This test standard is divided into methods A through H. 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.

Method F is used to measure the adhesive strength of rubber to metal bonding agents.

Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications.

ASTM D Rubber to Metal Adhesion Test Equipment

At the end of the test you will need to record the force vs displacement. The middle of the specimen is rubber which bonds the two cones together. The challenges of testing to this standard: This ensures that the line of tensile force remains concentric with the grip body. The assembly is cured in a degree Celcius oven for one hour. Peel fixtures provide atm condition of use to measure the bond strength between e429 surface coatings, films, packaging, and their rigid backings, as well as other bonded structures.

The metal pieces are made with tabs on the backsides for gripping in the test machine.

Test Method A helps determine the static adhesion strength of rubber to metal. Software asm Series Systems. How can we help you? Peel force is indicated in pounds per square inch of length of the peel line. A shear test is done until a break occurs at a depth of 5 mm at the rubber-metal bond interface. This test is often used to find which adhesive is best for the given rubber.
