Prior to use for extraction, the EDC solution shall be agitated for two hours and filtered. 4.6.3.1.2 Procedure. Approximately 2.5g of the dried sample shall be accurately weighed (recorded to
28、the nearest O. 1 mg) and quantitatively transferred to a 250 ml screw cap bottle. Add 150 ml of saturated EDC solution (see 4.6.3.1.1), attach the screw cap, and place the bottle on a mechanical shaker. The bottle shall be shaken at least thirty minutes, until visual examination indicates complete d

About 30 ml of the saturated EDC solution shall then be poured into the bottle, the screw cap replaced, the bottle shaken by hand, and the contents transferre
30、d to the filtering crucible. This procedure shall be repeated at least twice in order to remove all residue from the bottle. The bottle and cap shall then be rinsed twice with 30 ml aliquots of the EDC solution, with the washings being transferred to the filtering crucible. The crucible shall then b
31、e removed from the flask, 20 ml of saturated EDC solution shall be added, and the crucible shall be reconnected to the flask, allowing the liquid to filter through the residue. This procedure shall be performed a total of three times. The crucible shall then be removed from the flask and the interio
32、r portions beneath the glass frit shall be carefully rinsed with the saturated EDC. After rinsing, the crucible shall again be connected to the vacuum flask and aspirated for approximately two minutes. The crucible shall then be placed in an oven (100 +/- 5 degrees C) for one hour, or until dry. Aft
33、er cooling to room temperature the crucible shall be accurately weighed (recorded to the nearest 0.1 mg). The HMX content of the sample shall be calculated as shown below: % HMX = 100 (A-B) W A = Final weight of crucible, g B = Tare weight of crucible, g W = Sample weight, g” 6 Provided by IHSNot fo
