It is considered, the method of an estimation of uncertainty of definition of a mass fraction developed by authors and-or mass concentration of copper, lead, cadmium and zinc in foodstuff and raw material by polarography. Considering, that the information on entrance sizes is received by double supervision, regular and their casual components standard uncertainties are estimated by the type B. As in the standards regulating methods and processings of results, measurements considered in work, resulted a level of trust of the order of 95 %, by us are assumed, that probabilities of estimations of target sizes have Gauss (normal) distribution with factor of scope k = 2.
