Abstract :
The standards DIN EN ISO 10992 Part 1: 12-2003 and Part 5:11-1999 demand different tests for cytotoxicity including in vitro methods for evaluation materials in application of medical devices. Special features are materials for packaging processes in the field of medical micro devices. In this context the working group selected fundamental systems of materials and contact layers for testing in contact with the standard cell 3T3 clone A 31 and NCTC clone L929. One of the advanced methods includes a spectroscopic measurement of the metabolism. The results permit a gentle differentiation of materials cytotoxicity. Examples are shown in this paper.
