    Rationale: Users of this Standard Test Method have obtained lead balls which were slightly under the specified weight by less than 0.1 gram. Changing the weight specification by 0.1 gram on the lower limit should not materially affect the results of the dropping point test, and will enable users to more easily obtain proper lead balls. Only the section being revised appears on this ballot. Additions are shown in dark red underline while deletions are shown in dark red strikethrough. 5.1.4 Lead BallA lead ball weighing 3.20 g 0.10 g between 3.00 g and 3.30 g .
