Significance and Use
Diametral compression strength is an important measure of the mechanical properties of casting materials. This test method simulates the loading pattern seen in lower extremity casting applications during ambulation. This test method cannot be used to determine cast life or measure bending or other modes of cast failure.
This test method measures but does not prescribe values.
1.1 This test method covers the functional diametral compression strength of cylindrical test specimens formed from synthetic fiberglass polyurethane casting materials. The test specimens employed in this test method are similar in geometry and construction to casts used in orthopaedic applications. This test method is not intended to determine the strength of the base materials used for fabrication of the test specimen.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are given in 6.7.
