- ASTM-D575 – Standard Test Methods for Rubber Properties in Compression
ASTM D575 describes a method for measuring the compression-depression properties of rubber compounds. The deflection and force are typically reported.
These test methods are 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.
These test methods cover two test procedures for determining the compression-deflection characteristics of rubber compounds other than those usually classified as hard rubber and sponge rubber.
ASTM D575 Test Method A – Compression Test of Specified Deflection for Rubber
ASTM D575 (D-575) test method A is a procedure for determining the compression-deflection of rubber compounds (except hard rubber and sponge rubber). ASTM D575 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 D575 test method A is a compression test in which 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.
ASTM D575 Test Method B – Compression Test at a Force for Rubber
ASTM D575 (D-575) method b is useful in comparing stiffness of rubber materials in compression. ASTM D575 method B covers procedures for determining the compression-deflection of rubber compounds. 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. Deflection is the change in thickness of the specimen upon application of a compressive force.
