Trenton, Michigan * . ; Dear Dr. Jenkins: SUBJECT: Inerteen . . Pnrchasinc Departnent Specification No. 6935-1 ... I.'e- ce plpased to have received your letter oX. November 21 lender this subject inwhlch you. discuss several points, in connection with our specifications cohering Inerteett* Ne have '.the following comments in connection with our tentative Purchasing Department Specification No, 6935WI, date.d September 17, 1942 - . *.. i .a# , . We.are agreeable to changing the ej^eoifiQatlon to call far* 600 pounds of Inerteen per drum rather than specifying the Inerteen by weight. We suggest that the specification allow a plus or minus variation of five pounds, of Inerteen per drum as a satisfactory commercial variation* ~t ;% . - ., Since the possibility i of obtaining, dripis in'accordance with our specification is .rather, re-uote atithe present tine, we will scree to have your furnish the type of drum, you have been using for several years. In. connection with, this particular- type of drum fth.ieh your are usingv vie- . are wondering if there- would-.be any pbjection from the 1.8.to your shipping the drums up^idedo^nj that. is, with the. bungs pn the bottom. The purpose of this would be toavpid.the possibility of water getting into the Inerteen through the gasket on the bung, , When the drums are shipped with the bungs omtbe.t.op of the. drum, cults often the .bungs are oovered with water and it is entirely possible for the water to get into the Inerteen. . ; fte, of course, realize that there is a possibility of some of the Inerteen being lost due to leakage at the bung if the drums ere shipped in an inverted position, however, w feel that the loss of the Inerteen would not be as serious a matter as contamination with water. If this idea seems feasible -and also provided that the I,GC, has no objections, the drums should be marked in such a manner that the carriers would handle and ehip them in the Inverted position. (Over) DSW 331014 STLCOPCB4077658 Dr. R. L. Jenkins 2- Novenber 27, 1942 It will, of co iae, be satisfactory to mark the net content of tho drums In pounds rather than gallons. ` - . We will delete the'reference to the T.'estphnl balance in ' connection with the determination of specify cavity. This deletion will permit determining the specific gravity by any acceptable method, . including the hydrometer method you.use. . ,. Now in regard to the other proposed changes in our tentative Specification 6935-A, we would like to have your approval or com ants on the following proposed revisions. ' ' H. ' We would like to change the acidity of the Inerteen to 0.005 ;ag TIaOH/gram in place of the present figure of 0.01. -The test renorts . which we have available indicate that this value oan be easily met and we would very much prefer the lower value as the specified Unit. In connection i>ith the determination of acidity, we are agreeable to adopting the Monsanto method in place of the method now given in the specification. -* e* ' We would like to change the test method for determining the presence of free chlorides as given in Section 4 of the specification . from the A.S.T.lI, method to the :lonsanta method which, we assume, will be agreeable to you. It would be our intention to continue to call for the Inerteen to be free of free chlorides. , Y.'e would propose a change in viscosity from 46 - 49 seconds to 45-49 seconds. This change is being suggested on the basis of your test reports of 1940, 1941, and 1942. *. *- , i;e believe that it would be desirable to h ve the Inerteen meet the electrical resistivity test a icoified in Section 11 without - treating it as specified.in Section 11 (c).- '..1th that in .mind,, we- propose the elimination-of Section 11 (of from the specification. \ ' ' ," ' We plan On eliminating entirely Section 13 of the specifi cation which provides for a power factor determination at 100 C, 50 cycles and 20 - 30 volts per mil. -v The heating loss as now specified in Section 14 is sot at less than.0,4 per cent. We propose reducing this figure of 0.4 to 0.04 per cent. ' '. > . . Kill you please study these proposed changes and let us have your approval or consents on then at your earliest convenience. .
