ASTM F 2820 : 2024

1.1This specification covers virgin polyetherketoneketone (PEKK) polymer in virgin forms (for example, pellets, granules, powder, filaments used in additive manufacturing) and fabricated forms. It provides requirements and associated test methods for these thermoplastics when they are to be used in the manufacture of intracorporeal devices such as surgical implants or components of surgical or dental devices.

1.2The properties included in this specification are those applicable for PEKK polymers only. Indicated properties are for fabricated forms. Fabricated forms and materials containing colorants, fillers, processing aids, or other additives, as well as polymer blends which contain PEKK, or reclaimed materials are not covered by this specification.

1.3This specification is designed to recommend physical, chemical, and biological test methods to establish a reasonable level of confidence concerning the performance of virgin PEKK polymers for use in medical implant devices. The properties listed should be considered in selecting material(s) in accordance with the specific end-use requirements.

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

1.5When evaluating material in accordance with this specification, hazardous materials, operations, and equipment may be involved. 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.

1.6This 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.
