    Abstract

    Problems involved in the sampling of electrorefined cathode production in a typical refinery are examined. Items discussed include: nonhomogeneity in single cathodes, nonhomogeneity among cathodes from the same electrolytic cell, nonhomogeneity among cathodes from single production lots, and limitations of visual examination in predicting cathode quality. Ordinary sampling procedures involving one or two cathodes are shown to be totally inadequate for obtaining true measures of the average impurity contents from a shipping lot. Suggestions for sampling frequency drawn from the experience of the study are presented.
