FR Recognition List Number 055 Date of Entry 12/21/2020 
FR Recognition Number 2-281
ISO /TS 10993-19 Second edition 2020-03 Biological evaluation of medical devices - Part 19: Physico-chemical, morphological and topographical characterization of materials
This document provides a compilation of parameters and test methods that can be useful for the identification and evaluation of the physical, i.e. physico-chemical, 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 device's intended use (clinical application and duration of use) even if such properties overlap with clinical effectiveness.
This document does neither address the identification or quantification of degradation products nor the evaluation of the physico-chemical properties of the degraded materials, which are covered in ISO 10993-9, ISO 10993-13, ISO 10993-14 and ISO 10993-15.
Chemical characterization of materials is covered by ISO 10993-18.
The ISO 10993 series is not applicable when the material or device is not in contact with the body directly or indirectly.
Extent of Recognition
Complete standard
Rationale for Recognition
This standard is relevant to medical devices and is recognized on its scientific and technical merit and/or because it supports existing regulatory policies.
Transition Period
FDA recognition of ISO/TS 10993-19 First edition 2006-06-01 [Rec# 2-167] will be superseded by recognition of ISO/TS 10993-19 Second edition 2020-03 [Rec# 2-281]. FDA will accept declarations of conformity, in support of premarket submissions, to [Rec# 2-167] until December 18, 2022. After this transition period, declarations of conformity to [Rec# 2-167] will not be accepted.
