1 Scope
This standard specifies the method for determining impurities in milk and milk products.
This standard is applicable to the determination of impurities in raw and fresh milk, pasteurized milk, sterilized milk, condensed milk and milk powder; it is not applicable to milk and milk products containing substances which affect filtering and containing insoluble colored matters.
2 Principle
Filter the samples of raw and fresh milk, liquid milk and milk powder renatured by water with impurity filter plate, and determine the impurity limit of samples by comparing the visible non-white residual impurities on impurity filter plate with the impurity reference standard plate.
