Individual units of selective wear-metal standards each formulated at a specific PPM concentration level prepared in lubricating oil as the matrix for monitoring and predicting frictional wear of constituent machine parts. Typical wear-metal and concentration level combinations: Ag, Al, B, Ba, Ca, Cd, Cr, Cu, Fe, K, Mg, Mo, Na, Ni, P, Pb, Si, Sn, Ti, V and Zn each at 10 to 900 PPM. |
