| CORROSION OBSERVATIONS ON EXP: CARS. SHEET 2. CONDITION OF TEST & CAR TESTED WHETHER IRON HOT SPOT FITTED WHETHER STEAM VALVE USED WHETHER CORROSION INHIBITOR USED MILEAGE COVERED UNDER OBSERVATION TIME DURING WHICH OBSERVED REMARKS 1) 32 Ex: - 15000 MILES TEST IN FRANCE. CERTAIN AMOUNT OF FRESH WATER ADDED DUE TO LOSS DUE TO BOILING. NO. YES. YES. 17,000 3 MONTHS. ONLY SMALL AMOUNT OF CORROSION - NO CHOKING OF MATRIX. 2) 34 Ex: - LONDON TO NAIROBI & BACK DEMONSTRATION RUN. NO WATER ADDED THROUGHOUT MILEAGE. YES. YES. NO. 13,000 2 MONTHS. VERY SMALL AMOUNT OF CORROSION - LESS THAN IN (1) - NO CHOKING OF MATRIX. 3) 35 Ex: - 15,000 MILES TEST IN FRANCE - VERY LITTLE ADDED THROUGHOUT MILEAGE. NO. NO. NO. 20,000 3 MONTHS. SOME CORROSION BUT NOT SERIOUS - NO CHOKING OF MATRIX. 4) 39 Ex. - RUNNING IN ENGLAND. (PRESSURE COOLED SYSTEM FITTED) NO WATER REPLENISHMENT. NO. YES. YES. VERY SLIGHT CORROSION ONLY LESS THAN IN (1) ABOVE. NO CHOKING OF MATRIX. NOTE:- CORROSION REFERRED TO IS CORROSION OF ALUMINIUM C/CASE & CYL' HEAD WATER JACKETS. | ||
