Wear factor (K) is an indication of a materials resistance to wear as a function of the volume of material lost, force (load) and velocity at the wear interface and time. It is often determined using a “thrust washer” wear testing apparatus per ASTM D3702 in which a molded plastic specimen is rotated against a substrate thrust washer under set pressure and velocity conditions.

A wear factor is calculated with the equation W=K*F*V*T. In this equation W is wear volume (in3), K is wear factor (in3 min/ft lb hr)10-10, F is force (lb), V is velocity (ft/min), and T is elapsed time (hr).

A material with a lower wear factor (K) has greater resistance to wear and these values are useful for material comparison purposes.
