FTM-6503 "Mean Hertz Load of Extreme Pressure Lubricants"
The Mean Hertz load is the original basis of the ASTM D-2596 Load Wear Index test. By using mathematical models for the relationship between the hertz line, the contact area of the specimen balls under load, and the compensation load line, the elastohydrodynamic lubrication boundary, the ASTM D-2596 and ASTM D-2783 yield the same values. There appears to be no advantage to the more costly and time consuming FTM-6503 technique.
Can anyone translate this into english ?
Suppose a value of 45(kg) was compared to a value of 60(kg) .
Could you correlate this to something similar to part of the 4 ball wear test ?
Any help appreciated !
