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.

1.1 This test method2 covers the measurement of the adhesion characteristics of dry solid film lubricants.

1.2 The values stated in SI units are to be regarded as standard.

1.2.1 Exception—The values given in parentheses are provided for information only.
