ASTM D6547-00(2005)

Corrosiveness of a fluid to a bimetallic couple is one of the properties used to evaluate hydraulic or lubricating fluids. It is an indicator of the compatibility of a fluid with a brass on steel galvanic couple at ambient temperature and 50 % relative humidity.

1.1 This test method covers the corrosiveness of hydraulic and lubricating fluids to a bimetallic galvanic couple.

Note 1—This test method replicates Fed-Std No. 791, Method 5322.2. It utilizes the same apparatus, test conditions, and evaluation criteria, but it describes test procedures more explicitly.

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