ASTM D3233 for Measurement of Extreme Pressure Properties of Fluid Lubricants
ASTM D3233 Standard Test Methods for Measurement of Extreme Pressure Properties of Fluid Lubricants (Falex Pin and Vee Block Methods)
6. Apparatus
6.1 Falex Pin and Vee Block Test Machine, illustrated in Fig. 1, Fig. 2, and Fig. 3, fitted with 4500-lbf (20 000-N) gage or 3000-lbf (13 350-N) gage.
6.2 Required for Calibration:
6.2.1 Allen Screw, with attached 10-mm Brinnell ball.
6.2.2 Back-Up Plug.
6.2.3 Standard Test Coupon, soft, annealed copper, Hb 37–39.
6.2.4 Brinnell Microscope, or equivalent.
6.2.5 Timer, graduated in seconds and minutes.
6.2.6 Rule, steel, 6-in. (approximately 150-mm) long.
7. Reagents and Materials
7.1 Standard Coined-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 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.
7.3 Locking Pins, 1/2 H brass, conforming to Specification B 16/B 16M.
7.4 Solvent, safe, nonfilming, nonchlorinated.
NOTE 4 - Petroleum distillate and benzene, formerly used as solvents in this 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.
