The black powder shall be examined visually to ascertain that it has been glazed with graphite and that surfaces of the grains do not have a mottled appearance, which may indi

The dish shall be cove

(As an alter- native method, the portion may be dried for 72 i-ours at room temperature in a desiccator over concentrated Svifuric acid). Three such determinations shall be made and the a*re

Exactly 10 g of bi lk black powder or pressed pellets shall be weighed in an aluminum disposable pan liner, properly positioned, on the Ohaus Moisture Determination Balance. The infrared hea
43、t lamp that is built into the machine shall be moved directly over the powder sample, heat adjusted to the desired temperature, and time and wattage con- trols regulated to a setting based on a predetermined drying curve. The moisture determination shall then be read directly in either grams or perc
44、ent moisture loss with the accuracy of the final percent moisture or percent moisture loss based on the ac- curacy of the initial 10 g sample. The pan and dried powder shall be weighed until constant weight is obtained, or until the weight between weighings does not exceed one milligram. 4.5.2.2 Alt
