Description of ASTM-F1983 2014ASTM F1983-14Historical Standard: Standard Practice for Assessment of Selected Tissue Effects of Absorbable Biomaterials for Implant ApplicationsASTM F1983Scope 1.1 This practice provides experimental protocols for biological assays of tissue reactions to absorbable biomaterials for implant applications. This practice applies only to absorbable materials with projected clinical applications in which the materials will reside in bone or soft tissue longer than 30 days and less than three years. Other standards with designated implantation times are available to address shorter time periods. Careful consideration should be given to the appropriateness of this practice for slowly degrading materials that will remain for longer than three years. It is anticipated that the tissue response to degrading biomaterials will be different from the response to nonabsorbable materials. In many cases, a chronic inflammatory response may be observed during the degradation phase, but the local histology should return to normal after absorption; therefore, the minimal tissue response usually equated with “biocompatibility” may require long implantations. 1.2 The time period for implant absorption will vary depending on chemical composition implant size, implant location, and test subject species; therefore, the implantation times for examination of tissue response will be linked to the rate of absorption. No single implantation time is indicated in this practice. 1.3 These protocols assess the effects of the material on the animal tissue in which it is implanted. The experimental protocols do not fully assess systemic toxicity, carcinogenicity, teratogenicity, or mutagenicity of the material. Other standards are available to address these issues. 1.4 To maximize use of the animals in the study protocol, all toxicological findings should be recorded. There are some aspects of systemic toxicity, including effects of degradation products on the target organs, that can be addressed with this practice, and these effects should be documented fully. 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 and health practices and determine the applicability of regulatory limitations prior to use.
