CORROSION CASE HISTORIES: DIAGNOSES OF CORROSION FAILURES AND FAULTS BY THE BRITISH ENGINE BOILER AND ELECTRICAL INSURANCE CO. LTD.

More than 500 engineer‐surveyors are currently employed in this country by the above company to inspect, test and certify periodically a very wide range of mechanical and electrical plant, the primary objective being safe and efficient operation. Detection of faults due to corrosion plays a large part in these investigations, and to exemplify the work of the company's engineers in this field we reproduce below three case histories, the last of which involved the evolution of a special test method which could prove generally useful in similar problems of corrosion fatigue arising through vibration.
