The circuit “RELEASE FROM OBJECTS COVERED WITH PORCELAIN (VITREOUS) ENAMEL” is a collaborative (non-evaluative) interlaboratory test aiming at determining release from enamelled object used for cooking and baking. At present, manufacturers of enamelled products sold in the European market do not have a harmonized European measure specifying the requirements Porcelain (Vitreous) Enamel must meet in order to be considered compliant for food contact.
The first objective of the circuit is to explore the release from enamelled object comparing different testing approaches available in (similar) European or (specific) National measures or guidelines dealing with food compliance. The purpose of the study is to assess the traceability of elements, define the measurement uncertainty and the variability of the preparation phase. The results of the study will identify the detectable limits (LOQ and LOD) and technological boundaries that the European legislator must take into account when approaching this material.
The second objective of the study is to expand the evidence collected through the study on Ceramics performed by JRC in support of the revision of the Ceramics Directive to investigate the release of metals in food from Ceramic products and determine appropriate methodologies for testing them. The study included some enamelled objects, but in small number, not allowing to obtain significant evidence on this kind of material.
Each participating laboratory will receive an articulated set of samples that will have to be analysed entirely by following the relevant instructions. At the end of the collaborative trial, each laboratory will receive a report in compliance with ISO 17043 and ISO 13528 and usable for the purpose of the accreditation of one the methods, once indicated by the legislator. The participation to the interlaboratory is free and includes the shipping costs in Europe. PLEASE NOTE: samples are only available in a limited number. The nature of the study allows us to assign them to labs depending on the rank they score in the selection. The present study will involve maximum 30 labs.
