Technical guidelines on testing the migration of primary aromatic ...

For articles that:– are fillable and have a volume in the range of 500 ml up to 10 l– are (intended to be) in contact with food for infants and young childrenthe analytical result needs to be corrected for the difference in surface-to-volumeratio between the experiment and the real food contact conditions.For articles that:– fillable articles that have a volume below 500 ml or higher than 10 l.– articles for which it is not practical to estimate the relationship between thesurface of that material and the volume of food.the analytical result needs to be corrected for the difference in surface-to-volumeratio between the experiment and the food contact conditions of 6 dm 2 /kg.The analytical results have to be reported together with the expanded measurementuncertainty at the legislative limit, as referred in the EU-RL-NRL Network (EUR24105, 2009).9.2 Establishment of complianceAs regards polyamide kitchenware, the specific migration limit for PAAs is set as nondetectableexcept for those on the positive list of the relevant legislation (CAS 108-45-2, CAS 1477-55-0, CAS 106246-33-7). They should not release into foods or foodsimulants PAAs in a detectable quantity. The detection limit applies to the sum ofprimary aromatic amines. For the purpose of the analysis the detection limit for PAAsis set at 0.01 mg/kg food or food simulants.As regards melamine kitchenware, the specific migration limit for formaldehyde withhexamethylenetetramine is 15 mg /kg food.Compliance with maximum levels should be established on the basis of the levelsdetermined in the laboratory samples.The limit is exceeded when the analytical result is higher than the relevant specificmigration limit (SML) taking into account measurement uncertainty.9.3 Quality and safety9.3.1 Internal quality control and proficiencyOfficial control laboratories must comply with Regulation (EC) No 882/2004 on thesubject of additional measures concerning the official control of foodstuffs.Laboratories should be able to demonstrate that they have internal quality controlprocedures in place. Examples of these are the "ISO/AOAC/IUPAC Guidelines onInternal Quality Control in Analytical Chemistry Laboratories".Participation in appropriate proficiency testing schemes which comply with the"International Harmonised Protocol for the Proficiency Testing of (Chemical)Analytical Laboratories" developed under the auspices of IUPAC/ISO/AOAC and ISO17043.17
