1/ The copper plates (see 6.4) shall show no brown or black stains. Slight darkening or a slight
green stain in the lubricant is acceptable.
2/ At least three of the four exposed panels shall be free of any visible rust.
3/ The change in mass of the O-ring caused by the lubricant shall be with respect to that
produced by the reference fluid.
4/ The water shall form a continuous layer.
5/ In at least three of four tests.
6/ Apparent viscosity after storage shall be performed on original apparent viscosity test sample.
7/ There shall be no signs of damage.
3.5 Coating appearance. The lubricant shall form a uniform homogeneous coating and shall
be free of lumps, visible dirt, grit, water, or other foreign matter.
