Specifies methods for the determination of chemical and mechanical changes in poly(lactide)-based homopolymers, copolymers and/or blends induced under in vitro degradation testing conditions.

This document describes methods for the determination of chemical and mechanical changes in poly(lactide)-based homopolymers, copolymers and/or blends induced under in vitro degradation testing conditions. This document covers polymers based on L-lactide, D-lactide, and/or D, L-lactide monomeric units.

The purpose of this document is to compare and/or evaluate materials or processing conditions. This document also describes the fundamental physical and mechanical evaluations needed for an in vitro degradation characterization of an absorbable poly(lactide) or other hydrolysable material or device.

This document is applicable to poly(lactide)-based homopolymers, copolymers and/or blends in bulk or processed forms and used for the manufacture of surgical implants, including finished products (packaged and sterilized implants).

The test methods specified in this document are also intended to determine the in vitro degradation rate and related changes in material properties of polylactide-based copolymers and/or blends with various other comonomers, such as glycolid, trimethylene, carbonate and/or ε-caprolactone. Unless otherwise validated for a specific device, these in vitro methods cannot be used to definitively predict device behaviour under in vivo conditions.
