5、cification for Aero and Aero-Derived Gas Turbine Engine Lubricants RATIONALE Committee E-34 has decided that Appendix A, table A1 needs to be split into two tables, Table A1 Design data, and Table A2 Methods under development. There is also a need to update some method designations following the pub
6、lication of some SAE methods and also update the Composition section. 1. SCOPE This specification defines basic physical, chemical, and performance limits for 5 cSt grades of gas turbine engine lubricating oils used in aero and aero-derived marine and industrial applications, along with standard tes
7、t methods and requirements for laboratories performing them. It also defines the quality control requirements to assure batch conformance and materials traceability, and the procedures to manage and communicate changes in oil formulation and brand. This specification invokes the Performance Review I
8、nstitute (PRI) product qualification process. Requests for submittal information may be made to the PRI at the address in Appendix D Section D.2, referencing this specification. Products qualified to this specification are listed on a Qualified Products List (QPL) managed by the PRI. Additional test
9、s and evaluations may be required by individual equipment builders before an oil is approved for use in their equipment. Approval and/or certification for use of a specific gas turbine oil in aero and aero-derived marine and industrial applications is the responsibility of the individual equipment b
10、uilders and/or governmental authorities and is not implied by compliance with or qualification to this specification. 2. REFERENCES 2.1 Applicable Documents The publications referred to in this specification are listed in Appendix D, Section D.1. Reference in this specification to any related docume
11、nt means the edition and all amendments current at the date of use of that document. In the event of a conflict between the text of this document and references cited herein, the text of this document shall take precedence. 2.2 Other Applicable References Other applicable references are listed in Ap
12、pendix D, Section D.2 for information purposes only. 2.3 Definitions STANDARD PERFORMANCE CAPABILITY CLASS (SPC): Lubricant intended for normal service. HIGH PERFORMANCE CAPABILITY CLASS (HPC): Lubricant intended for more demanding service in which engine operating conditions and/or service duration
13、s require higher thermal capability. SAE INTERNATIONAL AS5780C Page 2 of 19 BATCH: The volume of basestock, additive or finished lubricant receiving final certification analysis and testing. PERFORMANCE REVIEW INSTITUTE (PRI): An SAE affiliate with the objectives of providing global, unbiased, indep
14、endent manufacturing process and product assessments and certification services. QUALIFIED PRODUCTS GROUP (QPG): A mandated body designated by the PRI Qualified Product Management Council (QPMC) in accordance with PRI PD2000. This body is responsible for assessing whether a manufacturers products co
15、mply with the relevant standards. The Mandated Body is known as a Qualified Products Group (QPG) and is composed of members from the Original Equipment Manufacturers (OEMs) and Government Agencies. The QPMC has mandated a QPG for Aerospace Gas Turbine Oils. QUALIFIED PRODUCTS LIST (QPL): A list of p
16、roducts qualified by the QPG to this specification and issued by the PRI. QUALIFICATION REFERENCE NUMBER (QRN): A unique reference number assigned by the QPG to each formulation qualified to this specification. 3. COMPOSITION The composition of gas turbine oils used in aero and aero-derived marine a
17、nd industrial applications shall be based on polyol ester base-stock chemistry. Other base-stock chemistries may be considered for qualification at the discretion of the QPG. Additives containing barium or organic compounds of titanium, and known or suspected carcinogens, are prohibited. If a tricre
18、syl phosphate (TCP) additive is used, the TCP additive shall contain less than 0.20% by weight in total of mono, di and tri-ortho cresyl isomers of tricresyl phosphate. All chemical ingredients contained in aviation turbine lubricants must comply with all legal, environmental, toxicological and regu
19、latory requirements of the countries in which the products are manufactured and sold. A Safety Data Sheet (SDS) or other equivalent document shall be available to cover these regulatory requirements. 4. TEST REQUIREMENTS The test requirements in this section are mandatory requirements for the initia
20、l qualification of turbine engine oils to this specification. These requirements are primarily aimed at civil aero and aero-derived marine and industrial applications, but that does not preclude their use for military applications where considered desirable. All tests must be conducted by laboratori
21、es approved for the purpose in accordance with Section 5. The tests are grouped into the following property categories: Physical Properties Chemical Properties Stability Properties Deposition Properties Tribological Properties AIR6056, “Gas Turbine Engine Lubricant Specifications: Current Technical
22、Review and Future Direction” provides useful information to the background of these properties and tests and the reasons for their inclusion in AS5780.
