1.   Scope

1.1   This test method covers in vitro degradation of hydrolytically degradable polymers (HDP) intended for use in surgical implants. It provides a detailed methodology for conditioning samples and suggests quantitative techniques for evaluating changes in properties (for example, mass, molar mass, and mechanical strength) over time.
1.1.1   For many types of HDPs, a correlation has been established between in vitro degradation per this practice and in vivo degradation for unloaded specimens (see X1.1.1).
