Two methods, solvent extraction and Karl Fischer, were investigated as means of measuring the moisture content of molded expandable polystyrene for use in Army Ordnance ammunition packaging. Both methods were satisfactory and gave results which were in agreement. The maximum allowable moisture content for molded expandable polystyrene was established. This moisture content is recommended for adoption in packing drawings and purchase specifications. A small sample inspection plan from MIL-STD-105B is also recommended for adoption.
