The wear in mm makes sense but what was the coupon? Was this test conducted under temperature? Was it conducted under pressure (was there a radial load if the test was rotary)? Was the base stock consistent? What is the surface roughness? What is the test duration?

This table is just numbers without the basic parameters.

I am overseeing some friction testing on our in house friction tester and indeed the performance of various products is widely variable however under some conditions, some products significantly out perform.

Timkin OK load test

weld is the amount of weight it took to damage the bearing surface (how much weight before the oil failed to lube)
wear is how much damage it did (how big of a scar it made at the fail point)
Cu strip is copper corrosion (IIRC I know it's copper (Cu) and I'm pretty sure it's corrosion but honestly I forget what it means)

That is if this is the Timkin OK test....
