When a 50~ layer was used, the accuracy of determination of the wear control was between I and 2~. When a roo/~ coating was used, it was possible to measure a wider range of wear, but only with a 5/l accuracy.

In addition, data are presented which illustrate the importance of several engine operating variables on engine rusting tendencies in the full-scale engine test. Close control of such variables as carburetor air humidity, blowby rate, fuel composition, and engine speed, load and operating temperature is necessary if consistent results are to 1)~ obtained.
