DIN EN 16277 specifies a method for the determination of mercury in animal feeding stuffs by Cold-Vapour Atomic Absorption Spectrometry (CVAAS) after microwave pressure digestion. The limit of quantification in the test solution should be 0,25 µg/l or lower. Using a test portion of 0,5 g and a volume of the test solution of 25 ml a limit of quantification of 0,0125 mg/kg or lower should be obtained. The European Standard is based on a test method developed by the Verband Deutscher Landwirtschaftlicher Untersuchungs- und Forschungsanstalten (VDLUFA) e. V. and verified by interlaboratory testing. This has been adopted by Technical Committee CEN/TC 327 "Animal feeding stuffs - Methods of sampling and analysis", the secretariat of which is held by NEN (Netherlands) within the framework of a mandate. The collaboration of DIN for the field of responsibility of CEN/TC 327 is performed through national Mirror Committee, Working Committee NA 057-03-03 AA "Futtermittel" ("Animal feeding stuffs") of the Food and Agricultural Products Standards Committee (NAL).
