ASTM F1829-23

1.1 This test method covers a method for determining the static shear disassembly force of modular anatomic glenoid components used in anatomic total shoulder arthroplasty prostheses.

1.2 Although the methodology described does not replicate all physiological force conditions, it is a means of in vitro comparison of modular anatomic glenoid component designs and the strength of the retention mechanism between the articular insert and glenoid backing under the stated test conditions.

1.3 This test method covers modular glenoid components comprised of a separate articular insert and backing. The insert and backing can be fabricated from any combination of the following materials: metal alloys, polymeric materials, composite materials.

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

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
