3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Standard performance capability class
Types of lubricating oils that meet general requirements.
3.2
High performance capability class
Satisfy the operating conditions and (or) service life requirements of the engine, and adapt to higher temperature lubricant types.
3.3
Batch
A group of base oils, additives or finished lubricants after final analysis and testing.
4 ingredients
Turbine engine lubricants should be based on polyol ester compounds, and should not use organic compounds containing barium and titanium. If using
Tricresol phosphate (TCP) additives, in which the mass fraction of ortho-isomer should not exceed 0.2%.
All chemical components of turbine engine lubricating oil should meet the laws, regulations, environmental protection and toxicological requirements of the country where it is produced and sold.
Material Safety Data List (MSDS) or other related documents to cover these requirements.
5 Technical requirements
The physical properties, chemical properties, stability properties, deposition properties, and friction properties of turbine engine lubricants should meet Table 1 to Table 5 respectively
The items listed in Appendix A can be completed as report items.
6 Quality inspection
Each batch of turbine engine lubricating oil should be inspected according to the items listed in Table 6.
AA
Appendix A
(Informative appendix)
Report item
The test is carried out according to the items listed in Table A.1.The main purpose is to provide engine original equipment manufacturers with important
Performance indicators; accumulate reliable data so that reasonable suggestions can be provided for technical specifications in the future. When the data accumulates to one
When a certain degree is set, parameter limits can be added to test items without parameter limits in Table A.1, so that the report items become the main part of this standard.
For example, in FED-STD-791 Method 5308, when the acidity value is required to change, the limit of metal quality change is added in this way.

Appendix B
(Normative appendix)
Corrosion and oxidation stability
B.1 Corrosion and oxidation stability tests should be carried out according to FED-STD-791 method 5308, and the following adjustments should be made.
a) Carry out three tests at 175 ℃±2.5 ℃, 204 ℃±2.5 ℃ and 218 ℃±2.5 ℃ respectively.
72 h;
b) Liquid medium or fluidized sand bath heating instrument can replace aluminum block heater;
c) Use cadmium-plated steel sheet instead of electrolytic grade silver test piece. When tested at 218 ℃, the application complies with AMS-T-9046, type 1, component C
The titanium replaces copper and magnesium. Under all test conditions, use stainless steel wire or nickel-chromium wire to fix the metal test piece, and two titanium alloy test pieces
The average value of the mass loss is regarded as the mass loss of the titanium alloy, and the temperature of the condensed water should be maintained at 18 ℃ ± 2.5 ℃;
d) The total acid value shall be tested according to SAE ARP 5088.
B.2 The impurity content in the oil after the experiment shall be determined according to the following test methods.
a) Gently pour the oil sample in the test tube into a weighed PTFE filter with a pore size of 10 μm, filter the oil sample and measure the volume of the filtrate.
product;
b) Test the viscosity and acid value of the filtrate. Petroleum ether should not be added to it;
c) Use rubber cleaning tools to remove the deposits of the test equipment, and use petroleum ether to clean the equipment and the filtered deposits, and
Dry the sediment, weigh and calculate the sediment content per 100 ml oil sample;
d) Use petroleum ether with a boiling range of 30 ℃ ~ 60 ℃ or use n-heptane instead of 1,1,1-trichloroethane (OT-620).
