Software d755 Series Systems. Report the median of values taken from three specimens. Email addresses can only contain letters, numbers and the following special characters: After measuring the thickness of the test specimen, place the specimen between the platens of the testing machine.
Place sheets of sandpaper between the rubber surfaces and the testing machine platens. Calculate the percent deflection on the basis of the original thickness of the qstm. Read the deflection on the dial gage at the end of the 3 second period. Subscribe to Our Newsletters. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.
The challenge of testing to this standard: It is important to review ASTM D in order asmt fully understand the test setup, procedure, and results requirements. Report the median of values taken from three specimens By means of our testing expertise and modular product design, we will help find the solution that is right for you.
ASTM D575-91(2012) Method A Rubber Properties in Compression
By means of our testing expertise and modular product design, we will help find the solution that is right for you. Bluehill LE for Basic Testing.
Repeat the loading cycle a second time.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user awtm. 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.

Force range of 5 kN asm kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column asmt are available in both tabletop and floor standing models. This test constitutes only one kind of compression stiffness measurement.
ASTM D D test method A is a procedure for determining the compression-deflection of rubber compounds except hard rubber and sponge rubber. Contact Us View Accessories Catalog.
Description Literature Contact Us 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. Deflection is the change in thickness of the specimen upon application of a compressive force. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! Accurate strain measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens.
ASTM D – 91() Standard Test Methods for Rubber Properties in Compression
Apply the force a third time until the specified deflection is again reached. ASTM standards can be used by rubber technologists to aid in development of materials for compressive applications.
Concrete, Asphalt and Rock. Read the deflection on the dial gage at the end of the 3 second period. 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. Test method B is a compression test d57 which the specified mass or compressive asm is placed on the specimen and the resulting deflection is measured and recorded.
