ASTM D Compression Test of Rubber

ASTM D is useful in comparing stiffness of rubber materials in compression. This part of ASTM D specifies the test conditions for determining compression-deflection characteristics of rubbers based on the general principles given in Method A of the standard only. ASTM D test method A is a compression test in which the force required to cause a specified deflection is determined.

Accurate strain measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens.

ASTM D575-91(2012) Method A Rubber Properties in Compression

They can be used by rubber technologists to aid in development of materials for compressive applications. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. Read the asrm on the dial gage at the end of the 3 second period. The reading shall not include any deflection caused by the jog force.

ASTM standards can be used by rubber technologists to aid in development of materials for compressive applications. The use of an LVDT eliminates the measurement of extraneous compliance in the loading system, which would otherwise result in a reported deformation from the crosshead extension that is greater than the actual deformation of the specimen. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

After measuring the thickness of the test specimen, place the specimen between the platens of the testing machine. Compression platens that are larger in diameter than that of the specimen being tested are astn recommended.

Software for Series Systems. We are confident that we have what you are looking for.

Platens should have rigid connections to the frame and load cell, and must be rated to a load capacity which exceeds forces generated during the test. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. Calculate the percent deflection on the basis of the original thickness of the specimen.

The reading shall not include any deflection caused by the jog force. Concrete, Asphalt and Rock. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. The sandpaper resists lateral slippage of the rubber at the contact surfaces and should be slightly larger than the specimen. We use cookies to improve your browsing experience.
