Biological evaluation of medical devices - Physico-chemical, morphological and topographical characterization of materials has-corrigendum BS EN 62770 is an1 Scope This document provides a compilation of parameters and test methods that can be useful for the identification and evaluation of the physical, i. e. physicochemical, morphological and topographical (PMT) properties of materials in finished medical devices. Such an assessment is limited to those properties that are relevant to biological evaluation and the medical devices intended use (clinical application and duration of use) even if such
