The U.S. Army Defense Ammunition Center DAC, Validation Engineering Division SJMAC-DEV was tasked by the Transportation Engineering Division, SJMAC-DET to conduct testing on the Intermodal Storage and Transport Frame ISTF, manufactured by Mobile Shelter Systems, Inc. The ISTF was evaluated by the testing procedures set forth in MIL-STD-1660. Stacking, vibration, edgewise rotational drop, incline impact, sling compatibility, forklifting, and disassembly testing were conducted on the ISTF units. Each unit sustained weld cracks that occurred at the base of the corner posts. These weld cracks are an area of concern and should be evaluated by the manufacturer and design improvements identified. Each unit had cracked welds along the base. Inspection also revealed that each unit had bent wire mesh. The bent wire mesh was located in the frame end walls and was not significant. The damage was caused by impact of the wooden and metal containers against the mesh. The ISTF units remained intact and were capable of safely handling ammunition after completion of testing. The ISTF units successfully completed the test requirements of MlL-STD-1660 and are approved for the transport of ammunition. Also, instructions should be provided with each ISTF to ensure proper assemblydisassembly.
