A shear test is done until a break occurs at a depth of 5 mm at the rubber-metal bond interface. Prepare the rubber specimen for this test by vulcanizing it to the metal material of the tank.

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 asfm placed vertically in the test machine.

The test machine should be equipped with swivel joints above and below to ensure uniformly distributed tensile force tensile force through the specimen assembly. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. The specimens are placed into the shear test fixture and the shear stress is placed on the bond line. 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.

F429 a steady tension load until the rubber either separates from the metal surface or ruptures.

The results are obtained by measuring the force necessary to separate a rubber from a metal surface. Works very well with flat, thin specimens Eccentric design increases gripping force with tension.

Precision grinding ensures a parallel surface profile of the platens and CNC machining provides ultra-close dimensional tolerances, while the honing and polishing processes guarantee smooth, true specimen cavities.

We also recommend serrated jaws on your grips to avoid sample slipping. Pneumatic grips also provide constant clamping force throughout the test to avoid specimen slippage.

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. To prepare the specimens for Method D, 6 rubber pucks are mounted in an assembly with a clamp to hold compressive force. CCSi UltraLife molds are designed, engineered, and manufactured to produce high quality specimens, over an extended service life!

The sample also lends itself to testing the effectiveness of different processing techniques and various adhesive systems. Force range of 5 astj 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. Next, place the specimen in the jaws attached to the fixed grip with the separating edge toward the operator. XyLive is the best choice axtm enable the test engineer to visually monitor the progress of the test vs the data on the computer screen.

The grips for holding the specimen in the testing machine depend on the type of specimen. Record the total force at the time of failure. To begin testing, place the test specimen in the jaws attached to the fixed grip with the separating edge toward the operator.

Maintaining unidirectional force throughout the process of peeling from a substrate.

Most of the tests involve orthogonal tensile strength or peel strength of the adhesion interface. The durable, hard chrome finish resists the corrosive and adhesive effects of most compounds, greatly improving overall durability and ease of maintenance. Have a astn about conducting the test for this standard?

The metal to rubber interfaces are convex. It opens to expose both horizontal specimen surfaces, greatly easing specimen removal. How can we help you?
