Production standardization and quality control for the manufacture of black powder are discussed. The powder is to conform to Spec JAN-223A. Results of Process I the impregnating S is dissolved in CS2 and Process II no CS2 is used are compared. Of 6 powder batches prepared by Process I, and 6 by Process II, one made by Process II from 6 micron charcoal and medium finess nitrate with ethanol as a slurry medium produced ballistic traces of 137 and 51.5 relative quickness as compared to the DuPont reference powder. The next best trace was 72 from a Process I batch. Duplication attempts indicated that factors and conditions involved in the processing are not sufficiently standardized. Manufacturing methods, production costs, and testing results are being analyzed.
