Using the remainder of the 2.5Kg sample originally selected (4.4.3.1), spread the sample over a sheet of clean white paper and visually examine for form and the presence of for
42、eign materials. O 4.5.8 Granulation (see 6.8). 4.5.8.1 Preparation of sample. Use approximately 1009 of the sample previously examined in 4.5.7. Completely extract the TNT content-using method 301.3 of MIL-CTD-650-using- a sufficient quantity of toluene (see 6.5) which was saturated with RDX. NOTE:
43、If lumps or large agglomerates are present in the sample a suitable and safe means, such as a rubber policeman, should be employed in breaking up the lumps without rupturing the RDX. Therefore, a grinding method should be avoided. After the extraction of the TNT has been completed and the toluene ha
44、s been completely aspirated, wash the RDX remaining in the crucible with 200 ml of cold anhydrous ether saturated with RDX or an equally suitable dehydrant which will not dissolve RDX.
