Abstract : Consideration of potential cost savings as well as material availability problems resulted in the initiation of a study by this agency to reevaluate the polyurethane foam cushioning requirements specified in the Fast Pack specification PPP-B-1672. Additional emphasis was given to this study when the AFLC Spares Packaging Standardization Committee established and assigned an action item to AFPEA to determine whether the Grade C polyurethane foam currently specified for Fast Pack cushion inserts could be replaced with Grade B material which was less expensive and easier to obtain commercially. An extensive test program was conducted on the Type I, III, and IV Fast Packs in which the dynamic cushioning performance of both Grade B and C polyurethane cushion inserts were evaluated over the weight ranges currently specified in Appendix G of MIL-STD-794 for several of the different pack sizes. It was concluded that the substitution of Grade B polyurethane foam for Grade C foam could not be justified because of the significant reduction in the range of items that could be adequately protected.
