Tom Carrico sampled six Aroclor products in drums immediately after filling. These samples were analyzed by the old method for electrical properties and moisture content. Moisture seemed to be essentially unaffected. Electrical properties (using power factor @ SO cy. and resistivity as indicators) showed degradation In all cases . At th~*g +-jrn<a "^kP^Wn fr> flnynnq, JUP were*
using a pigmented liner in the drums.
After switching to drums with an unpigmented liner, three products were sampled from drums in October in a manner similar to that used in the test above. Also samples were taken from the filling- spout prior to filling the drums sampled. In every case, again using old method resistivity and power factor as indicators, no degradation was evident.
In November five drums of Aroclor 1016 were sampled for electrical properties immediately after filling. Samples were also taken from the filling spout prior to filling each drum. This time the electrical properties were analyzed using the laboratory clean room and the new method. These samples also showed no degradation of electrical properties.
The power factor and resistivity data are attached for all
these tests. It shows that the change in linings has
improved the drummed quality for at least a short period of
time. It remains to be seen whether this quality will
remain at a constant level over a period of time similar
to normal storage conditions.
r
The test proposed by Research should give us an indication of this for our present clear lined drum as well as the new unlined drums. It should also give us a basis for making a decision on drum rinsing. Until all of the data are in, the project to modify the Dept. 246 drumming facility will be held.
