Critical aspects in the determination of the surface in contact with foods for migration testing of kitchen utensils: Results from two investigations by interlaboratory comparisons organised by the European Reference Laboratory for food contact materials
This report presents the results of investigations by ILCs and follow-up questionnaires which focused on the determination of the food contact surface area of kitchen utensils. The study also included a voluntary exercise on the determination of the envelope volume which constitutes a different technique to estimate contact with foods.
The objective of the study was to identify sources of error that appeared in a first ILC (ILC003 2013) previously reported (EUR 26477, 2013).A questionnaire was designed and all laboratories which had obtained a zU-score >2 or <-2 for any of the reported results in ILC003 2013 were kindly invited to reply. With the information gained from the questionnaire, some difficulties in the surface area measurement and the main issues in the determination of Hf and the envelope volume could be identified. Reasons why certain results reported during ILC003 2013 had been outside the tolerance limits could also be identified.
