In this review, the latest information is given about the reference materials for the determination of contaminants in milk and milk products. Certified reference materials for the determination of contaminating chemical elements, organochlorine pesticides, polychlorinated biphenyls, dibenzodioxins, dibenzofurans, and aflatoxin M<sub>1</sub> are presently available. Properties of these reference materials and possibilities for their use are discussed together with the maximum tolerances of contaminants in milk and milk products. The basic information about the producers and distributors of the reference materials in this area is provided. &nbsp;

Characteristic Mass

Certified reference materials (CRM) composed of propyl (11383-2019) and isopropyl (11384-2019) alcohols solutions were created for validation of measurement procedures and control of measurement errors of measurement results of mass concentrations of toxic substances (alcohol) in biological objects (urine, blood) and water. Two ways of establishing the value of the certified characteristic – mass consentration of propanol-1 or propanol-2 have been studied. The results obtained by the preparation procedure and comparison with the standard are the same within the margin of error.
