37、.3 Test methods.4.3.1 Phosphoric acid content. Pipet 5 mL aliquots of thesample into each of two separate 500 mL Erlenmeyer flasksallowing 30 minutes for complete drainage of the pipets. Add 200mL of distilled water to each flask. To the first flask add 2 mLphenolphthalein indicator (prepared as 0.1
38、 percent solution in 90percent ethyl alcohol by dissolving 0.1 g of phenolphthaleinpowder in 100 mL of 90 percent ethyl alcohol). To the secondflask add 2 mL of bromphenal blue indicator (prepared as 0.1percent neutralized aqueous solution). Titrate each sample withstandardized 2.0 N sodium hydroxid

Clean panels thoroughly, by sanding if necessary,and degrease with trichlorethylene. Panels shall be scored 1.25ins. from one end. Apply a u
44、niform coating of grease conformingto MIL-G-10924 to the lower 1.25 in. of surface of panels whichhave been weighed to the nearest mg. A spatula is used for thegrease application. Wipe off the outer edges of the panels witha clean rag. The grease coating shall weight 35 mg 5 mg.Dilute, as specified
45、in 4.3.4, a portion of the test sample andthe standard comparison compound specified in table II. Transferthe diluted solutions to test tubes of suitable size. Immersepanels completely in the test tubes by means of hooks made ofiron wire and let stand for 45 minutes. Remove each panel andrinse by ge
46、ntly immersing 5 times in a beaker of water. Placepanels horizontally on absorbent paper and compare visually.4.3.7 Inhibiting agents. Determine the presence of inhibitingagents as required in 4.3.7.1 and 4.3.7.2.4.3.7.1 Type I, II, IV, and V conditioners. Dilute the testsamples and comparison stand

If the ball bearing in the testconditioner is dulled to a lesser degree than the ball bearing inthe standard control
48、solution it indicates the presence ofinhibiting agents contrary to the requirements. (If the ballbearing retains its original luster in the control solution, adifferent kind of bearing should be obtained.)4.3.7.2 Type III conditioner.
