30、ay be waived at the option of the inspector if the fluid is “doctor sweet“ when tested in accordance with ASTM D4952. 4. The steam jet procedure for aircraft turbine fuel, in accordance with ASTM D381, shall be used. However, following the determination of the unwashed existent gum, the residue shal

31、l be extracted with n-heptane and the washed gum determined in accordance with ASTM D381 procedure for motor gasolines. Both unwashed and washed existent gum results shall be reported. 5. Product shall be miscible in all concentrations with JP-5 and JP-8. No gums, sludge, or insoluble material shall

32、 be formed. 3.3 Workmanship. The purging fluid shall be free from undissolved water, sediment, suspended matter, and shall be clear and bright. 3.4 Antioxidants. Immediately after processing and before the product is exposed to the atmosphere (such as during rundown into feed/batch tankage), add an

33、approved antioxidant formulation (3.4.1) or combination of approved antioxidant formulations in order to prevent the formation of gums and peroxides after manufacture. The concentration of antioxidant to be added shall be: a. Not less than 17.2 milligrams (mg) nor more than 24.0 mg of active ingredi

34、ent per liter (L) to products that contain blending stocks that have been hydrogen treated. b. At the option of the supplier, not more than 24.0 mg of active ingredient per liter may be added to products that do not contain hydrogen treated blending stocks. 3.4.1 Antioxidant formulations.
