Box 1737 Baltimore, Maryland 21203 v:\ . ..v-; . . . - - 3 Dear Kr. Brueksch* The following analyses are reported on the sample of T1KKMIN0L PR-2 submitted August 17# 1967* New THKRM3N0L FR-2 8/l'f/67 Sample Specifications Viscosity & 100 P., Centistokes Acid Number, m3 KQH/g faoioture, FrH 54.1 0.40 70 52 maximum Less than 0.01 Less than 50 The san^ple results on viscosity and sold number Indicate slight decomposition of the THFRICCNOL PR-2 heat transfer fluid. Although a specification maximum of 52 Cenfcistoken on viscosity 3 Hated, production mterial rarely exceeds 45 Centistokes on viscosity. Using this as the base and considering, also, the increased acid number, which exceeds our arbitrary limit of 0.2 mg KOH/g, we can make the fore going Judgment on decomposition. The moisture level at this point is quit satisfactory. Kay I suggest that you submit another sample of fluid for analysis the first week in October at which time we can make further Judgment on the condition of fluid in your system. ps>N STLCOPCB4088144 \ Mr. H* C.
