ASTM D2670 method for measuring wear properties of fluid lubricants
ASTM D2670 standard test method for measuring wear properties of fluid lubricants (Falex pin and Vee block method)
6. Apparatus
6.1 Falex Pin and Vee Block Lubricant Test Machine, illustrated in Figs. 1-3.
7. Reagents and Materials
7.1 Required for Calibration of Load Gage:
7.1.1 Allen Screw, with attached 10-mm Brinell ball.
7.1.2 Back-Up Plug.
7.1.3 Standard Test Coupon, soft, annealed copper, HB 37 to 39.
7.1.4 Brinell Microscope, or equivalent,
7.1.5 Timer, graduated in seconds and minutes, and
7.1.6 Rule, steel, 6-in. (approximately 150-mm) long.
7.2 Required for Test:
7.2.1 Standard Coined V-Blocks, 96 +/- 1° angle, AISI C-1137 steel HRC 20 to 24, surface finish 5 to 10 µin. (1.3 x 10(-7) to 2.5 x 10(-7) m), rms,
7.2.2 Standard Test Journals, 1/4-in. (6.35-mm) outside diameter by 1 1/4-in. (31.75-mm) long, AISI 3135 steel, HRB 87 to 91 on a ground flat surface, surface finish 5 to 10 µin., (1.3 x 10(-7) to 2.5 x 10(-7) m), rms,
7.2.3 Locking Pins, 1/2 H brass, conforming to Specification B 16.
7.2.4 Timer, graduated in seconds and minutes.
7.2.5 Solvent, safe, nonfilming, nonchlorinated.
NOTE 2 - Petroleum distillate and benzene, formerly used as solvents in this test method, have been eliminated due to possible toxic effects. Each user should select a solvent that can meet applicable safety standards and still thoroughly clean the parts.
