| Summary | This standard applies to the production of surgical implants polylactide copolymer and (or) the bulk blends or processed wood. This standard specifies the conditions determined in vitro degradation of these copolymers and (or) blends chemistry and (or) changes in mechanical properties. Specified in this standard test method for measuring in vitro with different comonomer (such as glycolide, trimethylene carbonate, ��-L lactone) polylactide-based copolymers, and (or) of the degradation rate of blends and material properties changes. These in vitro test methods can not be used to accurately predict material behavior under in vivo conditions. This standard applies to compare and (or) evaluation materials or processing conditions. |
