Abstract:	Summary The preparation of the bovine liver 12-02-01 reference material, its stabilization and homogeneity testing is presented. Evaluation of an interlaboratory comparison in which 31 laboratories took part using several analytical methods is described. From the results of the intercomparison, the contents of the elements Cd, Cu, Hg, Mn, Pb, Se, and Zn were certified, while for the elements Br, Co, Fe, K, Mo, Na, and Rb, information values were derived. Non-recommended values for the elements Ag, As, Ca, Cl, Cr, Cs, La, Mg, S, Sb, Sn, Sr, and V were also evaluated.Denoted as CZIM-liver in the report [23]
