This document gives guidelines for the establishment of a conversion relationship between the results of an alternative method and an anchor method, and its verification for the quantitative determination of the microbiological quality of milk.
NOTE The conversion relationship can be used (1) to convert results from an alternative method to the anchor basis or (2) to convert results/limits, expressed on a anchor basis, to results in units of an alternative method.
