ASTM D575 Compression Test of Rubber
ASTM D – Test Methods for Rubber Properties in Compression
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. Next Checking to see if you are a returning visitor…. Next Checking to see if you are a returning visitor…. Read and record the force required. Accurate strain measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2.

ASTM D575-91(2012) Method A Rubber Properties in Compression
The reading shall not include any deflection caused by the jog force. 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. E Deflectometer Deflection Gauge.
Glossary of Materials Testing Terms. Users of previous versions of asrm such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Repeat the loading cycle a second time. Deflection is the change in thickness of the specimen upon application of a compressive force. Platens should have rigid connections asm the frame and load cell, and must be rated to a load capacity which exceeds forces generated during the test.
Force range of 5 kN to kN 1, lbf tolbf C575 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. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!
ASTM D D test method A is a procedure for determining the compression-deflection of rubber compounds except hard rubber and sponge rubber.
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. Place sheets of sandpaper between the rubber surfaces and the testing machine platens. 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.
Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. The challenge of testing to this standard: Concrete, Asphalt and Rock. Available from a 1 mm 0.

Onsite Training At Your Facility. 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.
Apply a specified minor jog force for a period long enough to adjust the deflection gage, after which apply the full test force for 3 seconds. How can we help you? ASTM D is useful in comparing stiffness of rubber materials in compression.
