1、Designation: D6514 03 (Reapproved 2014)Standard Test Method forHigh Temperature Universal Oxidation Test for Turbine Oils1This standard is issued under the fixed designation D6514; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th
2、e year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers a procedure for evaluating theoxidation of inhibited lubricants in the presence of a
3、ir, copper,and iron metals.1.2 This test method was developed and is used to evaluatethe high temperature oxidation stability and deposit formingtendency of oils for steam and gas turbines. It has been used fortesting other lubricants made with mineral oil and syntheticbasestocks for compressors, hy
4、draulic pumps, and otherapplications, but these have not been used in cooperativetesting.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associ
5、ated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

Significance and Use5.1 Degradation of fluid lubricants because of oxidation orthermal breakdown can result
17、 in fluid thickening or in theformation of acids or insoluble solids and render the fluid unfitfor further use as a lubricant.5.2 This test method can be used for estimating the oxida-tion stability of oils. It can function as a formulation screeningtool, specification requirement, quality control m
