Tr. Dr-nald L. McClain vestinrhouse Electric Corporation F.O. Box 341 ' Bloomington, Indiana Subject: Capacitor Aroclor 1242 ve. MCS 1016 Dear Mr. McClain: On August 6, 1970 we sent to you the proposed specifications for MCS 1016 along with copy, of- our specifications for Aro clor 1242, so that the typical properties of these fluids could be compared conveniently. The two fluids appear very slmllar. You will recall that the purpose of MCS 1016 la to provide essentially the same characteristics as Aroclor 1242, except that higher chlorinated biphenyls have beei^ removed, to help alleviate the PCB 'pollution' prbblem. Our goal remains to be in large scale production of MCS 1016 "t*^by July 1, 1971. Pursuant to changing to MCS 1016, we sent a drum of it to you for examination and capacitor life test ing. Additional sample amounts can be made available, If needed, <. our laboratory has completed a capacitor.life teat? study of these fluids, extending over a period of 3,200 hours and In cluding exposure to voltage levels and temperatures consider ably in excess of the conditions prescribed In the commercltl acceptance teats fur the fluorescent lamp ballast type oapacltors used In our study. . These capacitors were 2,0 microfarad units of the type rated at 500 volts AC, and required to with stand 1.5*500 070 volta at 70#C for 750 hours. The severity of our test conditions la defined in the ettaohed data. The results, ore essentially the same for both of-the fluids and^reflect excellent stability and capacitor U f a . While the number of capacitors tested was~small (aix Aroolor 1242 and five MCS 10l6), the work waa done under very carefully NPC00011215 202941 controlled com klone in our we have an extensive research program on materials for use in capacitor electric systems. we would be most pleased to have you visit our laboratory to review not only MCS 1016 but also other work assigned to serve ottr mutual interests in capacitor dielectrics. our rather extensive new commercial facilities to produce MCS 1016 are being installed. As .are^commltted tg the .19X 1 production date, please give us-yottr'findings and views from'your testing work, at the earliest"appropriate time. ' Believing that you may like another copy of the specifications for MCS 1016 and Aroclor 1242, we are pleased to enclose them, Best regards, cs Enclosures P. 0.
