New Practice for Clinically Relevant Preconditioning of Polymer-based Bearing Materials for Non-Clinical Testing of Joint Arthroplasty Devices

1. Scope

The scope of the Committee shall be the development of standardized nomenclature and definitions of terms, test methods, recommended practices, guides, specifications and performance standards for medical and surgical materials and devices. The Committee will encourage research in this field and sponsor symposia, workshops and publications to facilitate the development of such standards. The Committee will promote liaison with other ASTM Committees and other organizations with mutual interests.

This work item was initially started by ASTM subcommittee F04.22 (Arthroplasty) in order to provide some much-needed direction and clarity around clinically relevant preconditioning processes (e.g., accelerated aging, etc.), and how they should be applied to non-clinical bench testing (e.g., static, fatigue, wear testing, etc) of joint arthroplasty devices. We are looking to collaborate across subcommittees to help with this task, and so we are reaching out to ask for your help as we strive to support our industry.

The title and scope are in draft form and are under development within this ASTM Committee.
