| ROLLS-ROYCE LIMITED. INSTRUCTIONS. To: E.F.C. Order No: PB104 Customer's No: X4430 Temperature Test of Paper Condensers. Six paper condensers, five R.R, and one U.S.A. Bosch, have been subjected to a heat test with a view to ascertaining their behaviour at various temperatures up to 80.0°C. It was known that long before the condenser reached that temperature, leakage would commence, and that the capacity values obtained at the higher temperatures would only be apparent capacities. Nevertheless it was decided to take them up to 80°C as it was thought that a condenser might, in exceptional circumstances, attain that temperature on the car. The condensers were tested in two groups of three each, made up as follows. Group A 1. Goshawk condenser N°494 with improved connections. cont'd.{John DeLooze - Company Secretary} Signed: This Sheet must be filed on completion of the work. RK 238 (300 Bks.) (SF 152. 6-11-18.)
