1、Designation:D430417Standard Specification forMineral and Synthetic Lubricating Oil Used in Steam or GasTurbines1This standard is issued under the fixed designation D4304;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of las
2、t revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers mineral and synthetic(APIgroup I,II,III,or IV)oils used in steam and gas turbinelubrication systems
3、 where the performance requirements de-mand highly refined mineral or synthetic base oils compoundedwith rust and oxidation inhibitors plus selected additives asneeded to control foam,wear,demulsibility,and so forth.Thisstandard may also be applied to“combined cycle”turbinesystems,where a single lub
4、ricant circulating system is used tosupply oil to a steam and gas turbine configured in tandemeither on a single or separate shaft for enhanced energyefficiency.1.2 This specification is intended to define the properties ofmineral and synthetic oil-based turbine lubricating oils that arefunctionally
5、 interchangeable with existing oils of this type,arecompatible with most existing machinery components,andwith appropriate field maintenance,will maintain their func-tional characteristics.1.3 This specification is intended to define only new lubri-cating oil before it is installed in the machinery.
6、1.4 This specification is intended to be used as a guide.It ispossible that oils that do not meet this specification mayperform satisfactorily in some turbines.1.5 This specification does not include API Group V fluids.For polyol ester fluids used to lubricate land-based gasturbines,the user is refe
