This test constitutes only one kind of compression stiffness measurement. Zero the load and position. ASTM recommends the use of two sheets of sandpaper, placed between each of the metal platens and the rubber sample. Deflection is the change in thickness of the specimen upon application of a compressive force.
Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. The challenges of testing to this standard are: 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.
Deflection D5755 Force per Area.
Read the deflection and calculate the percent deflection based on the original thickness of the specimen. ASTM D is a testing specification that determines the compression-deflection characteristics of rubber compounds. They can be used by rubber technologists to aid in development of materials for compressive applications.
Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Deflection is the change in thickness of the specimen upon application of a compressive force.
astk Place sheets of sandpaper between the rubber surfaces and the testing machine platens. ASTM D is useful in comparing stiffness of rubber materials in compression. E Deflectometer Deflection Gauge. Report the median of values taken from three specimens.
ASTM D575 Compression Test of Rubber
Read the deflection on the dial gage at the end of the 3 second period. G Spherical Seat Compression Platens. ASTM D D test method A is a procedure for determining the compression-deflection of rubber ast, except hard rubber and sponge rubber. The sandpaper resists asfm slippage of the rubber at the contact surfaces and should be slightly larger than the specimen.
ASTM D test method A is a compression test in which the force required c575 cause a specified deflection is determined. Please confirm that you agree with our privacy and cookies policy to submit this form. Work with us to find the right equipment for your ASTM standard.
Calculate the percent deflection on the basis of the original thickness of the specimen.
ASTM D Rubber Compression Testing – ADMET
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. We use astk to improve your browsing experience.
For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens.
This part of ASTM D specifies 5d75 test conditions for determining compression-deflection characteristics of rubbers based on the general principles given in Method A of the standard only.
