ASTM D – 91() Standard Test Methods for Rubber Properties in Compression
Email addresses can only contain letters, numbers and the following special characters: Read and record the force required. 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.
Calculate the percent deflection on the basis of the original thickness of the specimen. Accurate strain measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to astmm compression platens.
It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements.
Software for Series Systems. Email addresses must contain the symbol. Apply the force a third time until the specified deflection is again reached.
ASTM D575-91(2012) Method A Rubber Properties in Compression

Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: The sandpaper resists lateral slippage of the rubber at the contact surfaces and should be slightly larger than the specimen.
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. Have a question about conducting the test for this standard? 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.
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 D test method A is a procedure for determining the compression-deflection of rubber compounds except hard rubber and sponge rubber.
ASTM D test method A is a compression test in which the force required to cause a specified deflection is determined.
