Extreme care should be observed during testing. 4.5.2.1.2 Anal

30、ysis procedure. The primer-f uel shall be analyzed as follows : (a) Prepare an ether standard as a 100 percent level by taking 10 ml of U.S.P. reagent grade diethyl ether and dilute l:25 with benzene or other suitable solvent and place in a stoppered 300 ml flask. Take a 10 ml portion of primer fuel

31、 from each sample unit and di- lute l:25 with solvent just prior to evaluation.

Separation of nonvolatile components shall be as follows: (a) Take a 100 ml sample of primer fuel and evaporate on a gum bath a

33、pparatus at room temperature with an air rate of 1 CU ft/min when sample is almost evaprated, increase the temperature to 212 F for 1/2 hour. Weigh residue and report in gms/100 ml. If residue is more than 1 gm/100 ml retain for the pour point test. (Note further spectrographic analysis can be perfo

34、rmed on the resi- dues for identification.) (b) (c) 4.5.2.2.1 Pour point analysis. Pour point analysis shall be conducted as follows : (a) (b) Prepare residue samples from 4.5.2.2 that exceed 1 gm/lOO ml by chilling to minus 50 F for 4 hours. Rotate each sample in its evaporation container 90 degree

35、s to its horizontal plane. Failure of the residue to flow (by visual observation) within a 10 second per- iod shall constitute failure of this test. 4.5.2.3 Moisture, solubility, and d=ite ash. The moisture, solubility, a.nd white ash test shall be performed as follows: - (a) (b) (c) Prepare a 50 mi

36、 sample of primer fuel from each test sample in a clean pre-weighed crucible. Chill for 4 hours in a cold box at minus 50 F plus or minus 5“ F. Remove the samples one at a time from the cold box and observe over a black surface for ice crystals or undissolved solids through the bottom of the beaker.

37、 Transfer the exadned 50 ml test sample to a weighed crucible; plance in a ventilated hood and ignite; allow to burn until flame is natur- ally extinguished. Transfer the crucible to a muffle furnace until “a shing“ is complete. (a) The preaence of ice crystals, undissolved solids, or more than 0.00

(a) Take the test units that have passed the high temperature part of this test and place in a cold box controlled at minus 50“ F plus or minus 5“ F and hold for i44 hours. Remove units one a.t a time, weigh, record,

42、 and return to the cold box for functional test. Calculate the loss of weight for each test unit and the percentage of weight loss against the specific net weight. (b) A loss greater than 2 percent of the specified net contents shall constitute failure of this test. 4.5.2.5 Functional. Test sa.mples
