The present system of classifying slugs intended for canning provides for individual measurement of dimensions on first-run MZ material, but not for their individual weighing. While the total and average weights of this type of material are determined on batches of twenty, this operation is for purposes of accounting only, and no concern is normally attached to the functional aspects of varying weights. It is thought desirable to obtain information relative to this problem. Collection of such information constitutes one of the purposes of the present test. Other purposes include collection of information which will aid in: Evaluating the improvement in overall yield brought about by adoption of the MZ diameter slugs; establishment of more suitable minimum diameter limits for recovered slugs if the present ones prove unsatisfactory; and setting up inspection procedures, if indicated, to cover measurement of dimensions as well as of weights of recovered slugs. This report provides results of this test.
