Summary of Practice3.1 These procedures are laboratory techniques for estab-lishing additive compatibility with commercial aviation turbinefuels, with additives previously approved in standard fuels andwith the fuel system components used in commercial aircraft,including ta

11、nk coatings, sealants, and elastomers. Tests areconducted with Jet A/A-1 fuel at four times the maximumadditive concentration as recommended by the additive sup-plier. Immersion tests, with fuel system components only, areconducted in the more severe Reference Test Fluids, TT-S-735,Types III and VII

12、. The time and temperature of immersion testsare representative of aircraft use conditions and immersedcomponents are evaluated after exposure, using industry stan-dard methods. Comparisons are made with representativecomponents exposed to the base fluid with and withoutadditive.NOTE 1Data obtained

13、with Jet A/A-1 fuels can be applicable to Jet Bfuel or to aviation fuels specified by other organizations, with theagreement of the approving air frame/engine manufacturer.4. Significance and Use4.1 Additives are generally used to enhance a fuel propertysuch as oxidation stability or to improve fuel

14、 performance byproviding corrosion inhibition, protection against icing, metaldeactivation, and so forth.

Application of the procedures of this practice is intendedto disclose these adverse effects.4.2 Combinations of additives may exhibit antagonisticeffects on fuel properties or performance. Compatibility testingwith previously approved additives is intended to disc

18、lose suchantagonistic effects of incompatibilities.4.3 Fuel system components such as sealants, coatings, andelastomers are normally selected because of their resistance toa Reference Test Fluid, which is designed to be more severe tocomponents than standard fuels. Application of the proceduresof th

19、is practice is intended to disclose adverse effects ofadditives beyond the effects of the Reference Test Fluids.5. Procedure AAdditive Effects on Fuel5.1 Base Fuel required for Procedures A and B must meetthe Jet A or Jet A-1 requirements of Specification D 1655 andbe clay treated in accordance with

20、 the procedure of TestMethod D 3948, Appendix X1, “Preparation of ReferenceFluid Base.” It should exhibit a rating of 98 WSIM after claytreating by Test Methods D 3602 or D 3948. About 75 L (20gal) of base fuel is required for Procedures A and B. Store thebase fuel in clean epoxy-coated metal contai

21、ners and recheckthe WSIM rating after three months of storage.5.2 Prepare the test fuel by blending four times the maxi-mum recommended concentration of the additive into 38 L (10gal) of base fuel.NOTE 2If the maximum solubility level is below this concentration,prepare the test fuel accordingly.5.3

22、 All ASTM D 1655 specification tests and the followingadditional tests, should be run on the base fuel and the test fuel:D 3602 or D 3948 water separationD 2624 electrical conductivityD 156 Saybolt color bright and clear-visual inspection5.4 If tests on test fuel exceed the limits of D 1655, rerun a

23、second test fuel containing only the maximum recommendedconcentration of additive in accordance with 5.3 and report.6. Procedure BAdditive Compatibility with OtherAdditives6.1 Prepare duplicate test blends by mixing 100 mL of basefuel containing four times the maximum recommended con-centration of t

24、he candidate additive to 100 mL of base fuelcontaining, in turn, each of the previously approved additives(other than oxidation inhibitors) at four times their maximumrecommended concentrations. The resultant blend contains twotimes the maximum recommended concentration of eachadditive.NOTE 3Approve

25、d additives are listed in Specification D 1655 butProcedure B may also be applied to additives approved for aviation fuelsby other organizations.6.2 Divide each of the mixtures described in 6.1 into twoclear, tall glass containers (100 mL each). Put the duplicatesamples into dark, cold storage at 17

26、.8C (0F) for 24 h.Inspect immediately after removal from cold storage, forindications of precipitation, cloudiness, darkening, or othervisual evidence of incompatibility.6.3 Warm the samples inspected from cold storage, shake toremix any separated components, and hold at 38C (100F) for24 h. Inspect

27、them again for visual evidence of incompatibilityimmediately after cooling to room temperature. Keep fuelsamples in dark storage during conditioning and betweeninspections.NOTE 4Photographs are a useful record of results of compatibilitytesting.7.
