e. Allow part to drip dry.

f. When part has dried, suspend it in vapor of boiling heptanefor 30 seconds.

9. Allow.part to al’rdry.

h. Weigh each test ring“andblock to the nearest 0.1 mg.

i. Store specimens in desiccator until ready to use.

Lubricate the quarter segment of the specimen holder and the threadedsection.with grease conforming to MIL-G-23549. Apply the grease to be tested to thetest ring.surface,making sure that the entire wear surface is completelycovered with test grease. Mount the test block in the quarter segment (cleanlint-freecotton gloves should be used in handling the specimens)and positionboth in the specimen holdermaking sure that the quarter segment and block aresecurely positioned in the cylindrical slot. With one hand holding the testblock mount, tighten with a“torque wrench to 28.2 nm (250 in-lbs). Apply theadditionaltest grease to the area of the test block which overlaps the ringon both sides of the block. Place a 454 gram (g) (one pound) weight inposition on the bale rods. Align the two referencemarkers by adjustjng theturn buckle on the friction rod. Tighten locknutson the turn buckle.Position the friction force cut-off level. The cut-off level is set at 177.9N(40 1bf) for a 0.44 coefficientof friction. Adjust the amplitude ofosci1lation for a 90 degree arc.

4.7.3.7 Procedure. With the revolutioncounter set at zero start themachine and adjust the oscillating speed to 87.5 cpm making sure at this pointthat the reference markers are perfectly aligned. Add a 454 g weight at 60cycles and another 454 g weight at 120 cycles. Run until failure isencountered‘dueto excessive friction (cut-offu.44 coefficientof friction)or to 35,000cycles. After reaching 35,000 cycles, dismount and clean testblock. Measure wear scar width in accordancewith ASTM O 2714. The wear scarwidth shall conform to table I.
