ISO 10993-10 Fourth edition 2021-11
Biological evaluation of medical devices - Part 10: Tests for skin sensitization |
|
Scope/AbstractThis document specifies the procedure for the assessment of medical devices and their constituent materials with regard to their potential to induce skin sensitization.
This document includes:
- details of in vivo skin sensitization test procedures;
- key factors for the interpretation of the results.
NOTE Instructions for the preparation of materials specifically in relation to the above tests are given in Annex A.
|
|
Extent of Recognition
| Partial recognition. The following part(s) of the standard is (are) not recognized: |
Clause 4 General principles - Step-wise approach
Annex C
|
|
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.
This standard is recognized in part because:
Clause 4 and Annex C are in conflict with an existing published FDA guidance. See Section B (page 20) of the guidance listed below, which states "With the advancement of scientific knowledge regarding the basic mechanisms of tissue responses, FDA agrees with the ISO 10993-1:2009 revision focus on minimizing the 'number and exposure of test animals by giving preference to chemical constituent testing and in vitro models, in situations where these methods yield equally relevant information to that obtained from in vivo models.'" |
|
ASCA Notes
The following test methods are included in the ASCA pilot program:
Guinea Pig Maximization Sensitization, in conjunction with ASTM F720-17 (recognition number: 2-256);
Closed Patch Sensitization.
