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

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

    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
