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. Before the load is applied, strip the rubber from the metal plate by using a sharp knife. First, pull a quality control test piece from each molded batch to determine that per cent adhesion is obtained prior to environmental exposure or laboratory storage with a pre-strain.

CCSi UltraLife molds feature a unique cam-action hinge design which improves the critical distribution of pressure. Most of the tests involve orthogonal tensile strength or peel strength of the adhesion interface.

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. D49 further facilitate mold opening and reduce the occurrence of cavity damage qstm improperly positioned tools.

Next, place the specimen in the jaws attached to the fixed grip with the separating edge toward the operator. How can we help you?

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Method B describes a peel procedure to determine the adhesive strength between rubber materials to a metal plate or substrate. Apply the tension load at 2 inches per minute until the rubber either separates from the adhesive surface or until the rubber ruptures. Results are obtained by measuring the pull load necessary to separate a rubber strip from a metal surface at a 90 degree angle.

Method G of ASTM D measures the bond strength of rubber to metal components with a double shear cylindrical specimen.

ASTM D429 – 14

Test Method C of ASTM D helps determine the adhesive strength of rubber-to-metal bonding agents when applied to conical or cone-shaped samples. The test is an orthogonal tensile test where the puck is pulled apart in tension.

We are confident that we have what you are looking for. Next, take the assembly out of the oven and take it apart to create six test specimens. Record the total force zstm the time of failure. Place the tab in the grip and apply a steady load at the rate of 50 mm 2. The assembly is cured in a degree Celcius oven for one hour.

It opens to expose both horizontal specimen surfaces, greatly easing specimen removal. Record the total load at the time of failure.

Load ratings from 1 kN to 10 kN s429 to 2, lbf Maximum specimen thicknesses of 7 mm or 8 mm 0. It is difficult to f429 the data correctly and provide consistent results. Test Method D helps determine the adhesive strength of rubber-to-metal bonding agents when the bond is formed after the rubber has been vulcanized.

We also recommend serrated jaws on your grips to avoid sample slipping. The results are obtained by measuring the force necessary to separate a rubber from a metal surface.

Create specimens that are 25 mm thick with a 29 mm diameter. 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.
