Compression platens that are larger in diameter than that of the specimen being tested are also recommended. Compression Test of Specified Deflection- A compression test in which the force required to cause a specified deflection is determined.

Reading should not include the deflection caused by the minor force. Deflection Percentage Force per Area.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. ASTM recommends the use of two sheets of sandpaper, placed between each of the metal platens and the rubber sample.

The challenges of testing to this standard are: Subscribe to Instron News! This test constitutes only one kind of compression stiffness measurement. Sales Support Calibration Calculators. 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. 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 the force a third time until the specified deflection is again reached. They can be used by rubber technologists to aid in development of materials for compressive applications.

Contact Us Request an Accessory Catalog. Deflection percentage is based on the thickness of the specimen prior to the first force application. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen d5575 from 56 mm to mm 2.

ASTM D – Test Methods for Rubber Properties in Compression

ASTM D test method A is a compression test in which the force required to cause a specified deflection is determined. Read and record the force required. This method involves one kind of compression stiffness measurement and covers two procedures: Calculate the percent deflection on the basis of the original thickness of the specimen. Report the median of values taken from three specimens By means of our testing expertise and modular product design, we will help find the solution that is right for you.

Work with us to find the right equipment for your ASTM standard. Apply the specified minor force. Email addresses must contain the symbol.

ASTM standards can be used by rubber technologists to aid in development of materials for compressive applications. After measuring the thickness of the test specimen, place the specimen between the platens of asm testing machine.

Test method B is a compression test in which the specified mass or compressive force is placed on the d5755 and the resulting deflection is measured and recorded. Have a question about conducting the test for this standard? Compression Test at a Specified Force- A compression test in which the specified force is placed on the specimen and the resulting deflection is determined. This test method is applicable to all rubber compounds other than hard rubber and sponge rubber.
