3.2 Definitions:
3.2.1 dry solid film lubricants, n—dry coatings consisting of lubricating powders in a solid matrix bonded to one or both surfaces
to be lubricated.
4. Summary of Test Method
4.1 The dry solid film lubricant is applied to anodized aluminum panels, immersed in water or other fluids for 24 h, and then wiped
dry. A strip of masking tape is pressed onto the panel and removed abruptly. Film removal exposing the surface of the metal panel
is the criterion for failure.
5. Significance and Use
5.1 Effective solid film lubricant coatings must adhere to surfaces to provide adequate lubrication in applications with restricted
access where fluid lubricants cannot easily be replenished. Loss of coating adhesion results in metal to metal contact causing
significant wear of contacting surfaces. Adhesion is critical to the performance of the solid film lubricant. Examples of solid film
lubricant applications include fasteners, bearings and sliding members in automotive, aircraft, and aerospace hardware.
5.2 This test method is intended to determine the adhesion of solid film lubricant coatings when submitted to contact with water
and other fluids. Results of this test provide an indication of the suitability of the lubricant coating in applications where contact
with water or other fluids is likely.
6. Apparatus
6.1 Rubber Covered Steel Roller—A steel roller, 82.6 mm 6 2.5 mm (3.25 in. 6 0.1 in.) in diameter and 44.5 mm 6 1.3 mm

6 5. The mass of the roller proper which applies pressure to the specimen shall be 2.04 kg 6 0.05 kg (4.5 lb 6 0.1 lb). It shall
be so constructed that the mass of the handle is not added to the mass of the roller during use.
6.2 Stylus, or equivalent.
6.3 Oven, forced-circulation, capable of maintaining 149 °C 6 5.5 °C (300 °F 6 10 °F).
6.4 Micrometer, reading 0 mm to 25 mm 6 0.0025 mm (0 in. to 1 in. 6 0.0001 in.) with a 1-ball anvil.
