Résumé

National Standard GOSTR 55575—2013 Bulk food products. Determination of ferrous foreign matters by magnetic method of operating precipitation and extrapolation is applicable to bulk food products and establishes an experimentally calculated magnetic method of operational extrapolated isolation for the identification and quantification of impurities with magnetic properties. Quantitative determination of ferroimpurities is carried out by experimental calculation by extrapolation of the obtained dependence of the decrease in the masses of the isolated ferroimpurities from the number of operations performed to the field of infinity and the calculation of the sum of the terms of the resulting decreasing geometric progression of the masses of the isolated ferroimpurities. It is allowed to use other measuring instruments, auxiliary equipment that are not inferior to metrological and technical characteristics and provide the necessary measurement accuracy.
