Report of two Inter-laboratory comparisons from the European Reference Laboratory for Food Contact Materials - Elements from Food Contact Materials: ILC 03 2014 – Plastics and ILC 04 2014 – Ceramics
This report presents the results of two proficiency tests (PT) organized by the EURL-FCM, which focused on the determination of elements migrated from food contact materials .Two exercises of Interlaboratory Comparisons (ILC) were conducted. One to determine the concentrations of the metals with migration limits assigned for plastics in European Regulation 10/2011 [1] and one to determine the migration of metals relevant to ceramics. The first ILC consisted on the quantification of Ba, Co, Cu, Fe, Mn, Zn, Li and Sb (Sb was undisclosed for participants) in acetic acid solution 3%. The second ILC consisted on the quantification of Ba, Co, Mn, Pb, Cd, Ni, As, and Al in acetic acid solution 4%. The general aim of the exercise was to assess the competence of official control laboratories to measure elements that can potentially migrate from food contact materials. The exercise was a proficiency test and so participants were free to use their own analytical methods. The assigned values were derived from the consensus of the resulted submitted by participants. The robust mean was chosen as the assigned value. The standard deviation for proficiency assessment was set at a value that reflected best practices for the analysis in question, at a maximum of 22 % of the assigned value based on the modified Horwitz equation. Fifty five laboratories (28 NRLs, 26 Official Control Laboratories OCLs and the EURL-FCM) from 27 countries registered to the exercise and fifty four reported results. The outcome of this exercise was satisfactory. The rate of success was always higher than 90% for all elements in both simulants (and 80% for Arsenic as extra element).
