ASTM D6514 Standard Test Method for High Temperature Universal Oxidation Test for Turbine Oils
1. Scope
1.1 This test method covers a procedure for evaluating the oxidation of inhibited lubricants in the presence of air, copper, and iron metals.
1.2 This test method was developed and is used to evaluate the high temperature oxidation stability and deposit forming tendency ofoils for steam and gas turbines. It has been used for testing other lubricants made with mineral oil and synthetic basestocks for compressors, hydraulic pumps, and other applications, but these have not been used in cooperative testing.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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. IDENTIFIED HAZARDOUS CHEMICALS ARE LISTED IN SECTION 7. BEFORE USING THIS TEST METHOD, REFER TO SUPPLIERS' SAFETY LABELS, MATERIAL SAFETY DATA SHEETS AND OTHER TECHNICAL LITERATURE.
