1.1This practice covers a procedure for the fatigue testing of metallic tibial trays used in knee joint replacements using a cyclic, constant-amplitude force. It applies to tibial trays that cover both the medial and lateral plateaus of the tibia. This practice may require modifications to accommodate other tibial tray designs.
1.2This practice is intended to provide useful, consistent, and reproducible information about the fatigue performance of metallic tibial trays with one unsupported condyle. The results are applicable to the laboratory test conditions and may not correlate with in vivo performance.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This 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.
