On August 1st , 2024, supplementing Council of Europe Resolution CM/Res(2020)9 , the European Directorate for the Quality of Medicines & HealthCare (EDQM) published 2nd Edition of Technical guide for manufacturers and regulators on METALS AND ALLOYS used in food contact materials and articles.

It features modified safety data concerning specific release limits (SRLs) for chromium, manganese, thallium and a new section on zirconium and general recommendations for release testing. The updated methods for the measurement of certain articles facilitate the calculation of specific release for control laboratories.
