Significance and Use

5.1 This test can be a guide to end-users on the formation of lubricant-generated, insoluble deposits.

5.2 The results from this test are intended to be used as a condition monitoring trending tool as part of a comprehensive program, as outlined in standards such as Practice D4378.

1. Scope

1.1 This test method extracts insoluble contaminants from a sample of in-service turbine oil onto a patch and the color of the membrane patch is analyzed by a spectrophotometer. The results are reported as a ΔE value, within the CIE LAB scale.

1.2 This test method is not appropriate for turbine oils with dyes.

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.
