A study was made to evaluate the performance of waxresin impregnated fiberboards and containers for applicability for use in shipment overseas under all environmental conditions, and as a substitute for conventional weather resistant materials which may become critical and are in short supply during periods of emergency. Sixteen different tests were performed conforming to ASTM Standards or to the requirements of Federal Specifications, utilizing up to 5 different environmental conditions standard, arctic, hot desert, rain and tropical. It was found that wax impregnation contributes significantly to increased compression strength through increased resistance to water absorption, and containers of wax impregnated board were superior to other grades of fiberboard in compression resistance. Differences in rough handling were negligible. This was related to the findings that wax impregnation had little effect on dry puncture resistance and on the Mullen bursting strength. Test results indicate that 275 pound test is the minimum grade which should be considered for the wax impregnation process for Military use in overseas shipment.
