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 is useful in comparing stiffness of rubber materials in compression.

They can be used by rubber technologists to aid in development of materials for compressive applications. ASTM D test method A is a compression test in dd575 the force required to cause a specified deflection is determined. Deflection is the change in thickness of the specimen upon application of a compressive force.

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.

The sandpaper resists lateral slippage of the rubber at the contact surfaces and should be slightly larger than the specimen. Repeat the loading cycle a second time. Apply the force a third time until the specified deflection is again reached.

Read and record the force required.

ASTM D Compression Test of Rubber

Deflection percentage is based on the thickness of the specimen prior to the first force application. ASTM standards can be used by rubber technologists to aid in development of materials for compressive applications. This test constitutes only one kind of compression stiffness measurement. 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.

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. Read the deflection on the dial gage at the end of the 3 second period.

The reading shall not include any deflection caused by the jog force. Calculate the percent deflection on the basis of the original thickness of the specimen. Report the median of values taken from three specimens.
