Designation

This standard is issued under the fixed designation F3090; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (ε) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1

This test method is intended to evaluate the fatigue strength and performance of metallic acetabular shells with hemispheric outer surfaces.

1.2

This test method, as described, is not intended to evaluate the following: the strength of components that may be mated with the acetabular shells (for example, augments, acetabular liners); attributes of the shells not related to strength (for example, fixation, coating adhesion); the strength of acetabular shell features away from, or loaded differently than, the primary load bearing region of the shell (for example, screws, spikes, flanges); non-hemispherical shells (for example, patient-matched geometries); or corrosion between modular components.

1.3

Modifications to this test method (for example, different support medium, different size/position of unsupported region, different testing environment) may result in a method appropriate to evaluate the characteristics listed in 1.2. Such modification must have adequate justification.

1.4

Although the methodology described does not replicate all physiological force conditions, it is a means of in vitro comparison of acetabular device designs under repeated forces.

1.5

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6

This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
