Standard Practice for Extraction of Materials Used in Medical Devices Ingestion-build-209418 They are used to regulate1. Scope 1. 1 This practice covers methods of extraction of medical plastics and may be applicable to other materials. This practice identifies a method for obtaining extract liquid for use in determining the biological response in preclinical testing. Further testing of the extract liquid is specified in other ASTM standards. The extract may undergo chemical analysis as part of the preclinical evaluation of the biological response, and the material
