(Test Method)Standard Test Method for Corrosion Characteristics of Solid Film Lubricants
Standard Test Method for Corrosion Characteristics of Solid Film Lubricants
SIGNIFICANCE AND USE
5.1 Surfaces are examined for signs of corrosion. Any sign of corrosion is an indication of potential field failure.
SCOPE
1.1 This test method2 covers the evaluation of the corrosion characteristics of dry solid film lubricants under conditions of high humidity.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
