ASTM D Compression Test of Rubber

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.

This part of ASTM D d5755 the test conditions for determining compression-deflection characteristics of rubbers based on the general principles given in Method A of the standard only. They can be used by rubber technologists to aid in development of materials for compressive applications.

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. Repeat the loading cycle a second time.

ASTM D575 Compression Test of Rubber

Report the median of values taken from three specimens. It is important to review ASTM D in order to fully understand the test setup, procedure, and results requirements. ASTM standards can be used by rubber technologists to aid in development of materials for compressive applications. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available v575 both tabletop and floor standing models.

Description Literature Contact Us This part of ASTM D specifies the test conditions for determining compression-deflection characteristics of rubbers ast on the general principles given in Method A of the standard only. Accurate strain measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens.

ASTM D test method A is a compression test in which the force required to cause a specified deflection is determined.

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.

Apply the force a third time until the specified deflection is again reached. Deflection is the change in thickness of the specimen upon application of a compressive force. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Accurate xstm measurement – For improved accuracy, a linear variable displacement transformers LVDT can be attached to the compression platens.
