ASTM D2625 – Endurance (Wear) Life and Load-Wear Carrying Capacity of Solid Film Lubricants (Falex Pin and Vee Method)
Bonded solid film lubricants protect metal surfaces from wear during normal and extreme pressure operations. These lubricants are exceptionally attractive for use in inaccessible locations, and where cleanliness is a concern. This test uses a Falex Pin and Vee Block Test Machine to evaluate the solid film's (1) ability to protect metal from wear (Procedure A), or (2) load-carrying capacity (Procedure B).
In Procedure A, the vee blocks and pins are coated and cured with the test solid film lubricant, placed in the machine and aligned. The machine is run for a break in period and load is slowly added until the test conditions are reached. A steady state torque value is obtained. The machine is then run and the time it takes for either a torque increase of 10 in-lbf or a pin breakage is recorded and reported.
In Procedure B, the vee blocks and pins are likewise coated and cured with the test solid film lubricant, the machine is set up as above and the steady state torque is determined. The load is increased in one minute increments until the pin breaks or the torque rises by 10 in-lbf (1.13N m). Reported is the last load that was sustained for one minute.
