ASTM D – Test Methods for Rubber Properties in Compression
Deflection is the change in thickness of the specimen upon application of a compressive force. Email addresses can only contain letters, numbers and the following special characters: Subscribe to Our Newsletters. 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.
Report the median of values taken from three specimens. Description Literature Contact Us F575 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.
Email addresses must contain the symbol. ASTM D D test method A is a procedure for determining the compression-deflection of rubber compounds except hard rubber and sponge rubber. Test method B is a compression test in which the specified mass or compressive force is placed on the specimen and the resulting deflection is measured and recorded. WaveMatrix 2 for Dynamic Testing.
After measuring the thickness of the test specimen, place the asstm between the platens of the testing machine. Place sheets of sandpaper between the rubber surfaces and the testing machine platens. Standard load ratings up ast, kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. Bluehill LE for Basic Testing.
ASTM D575 Compression Test of Rubber
Place sheets of sandpaper between the rubber surfaces and the testing machine platens. 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.
Accurate strain measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens. By means of our testing expertise and modular product design, we will help find the solution that is right for you.

Calculate the percent deflection on the basis of the original thickness of the specimen. Bluehill LE for Basic Testing. Apply the force a third time until the specified deflection is again reached.
The use of an LVDT eliminates the measurement of extraneous compliance in the loading system, which would otherwise result in a reported ast 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.
It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.
Apply the force a third time until the specified deflection is again reached. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental wstm humidity chambers, furnaces, baths and custom solutions for unique applications.
Read the deflection on the dial gage at the end of the 3 second period.
We are confident that we have what you are looking for. This test constitutes only one kind of compression stiffness measurement. ASTM D is useful in comparing stiffness of rubber materials in compression. Check this box to receive pertinent awtm email from Instron focusing on products, upcoming events, and more! Apply a specified minor jog force for a period 5d75 enough to adjust the deflection gage, after which apply the full test force for 3 seconds.
ASTM D D test method A is a procedure for determining the compression-deflection of rubber compounds except hard rubber and sponge rubber. Available from a 1 mm 0.
E Ast, Deflection Gauge. They can be used by rubber technologists to aid in development of materials for compressive applications. Accurate strain measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens. Glossary of Materials Testing Terms.
