Insert stopper, invert the cylinder twice, and place on a level surface; a homogeneous emulsion should be formed. If not, the product is not acceptable. If the water/product emulsi

29、on is satisfactory, allow to stand undisturbed for 1 hour and inspect for separation layer between water phase and solvent phase. If any phase is evident, report this in milliliters. Shake the sample by inverting the cylinder through 20 inversions in less than 10 seconds. Allow to remain undisturbed

30、 for 48 hours and re-inspect for phase separation. Report phase separation in milliliters. Any separation beyond 5 mL is not acceptable. 3.2.9 Foaming Properties The product shall remain on unpainted aluminum alloy surfaces not less than 1 minute, determined in accordance with 3.2.9.1. 3.2.9.1 Using

31、 equipment conforming to MIL-C-81762, the cleaner shall be applied to an unpainted panel of AMS4049 aluminum alloy, 36 inches (914 mm) square, which has a line scribed 3 inches (76 mm) from the bottom. With the panel held in a horizontal position, the cleaner shall be applied from a 6 foot (1.8 m) f

32、oam wand assembly and the foam generator regulated to ensure a minimum live water pressure of 30 psi (207 kPa), air at 40 to 60 psi (276 to 414 kPa), and a cleaner/water ratio at use dilution recommended by the manufacturer. Cover panel completely with foam except for the area below the scribed line

33、. Within 10 seconds after application of cleaner, the panel shall be held at an angle approximately 60 degrees to the horizontal. When the foam crosses the scribed line, start timing and measure the time required for the first signs of foam dropping off the panel. Also, measure the time required for

34、 the foam to completely drop off the panel. Repeat the test twice with a clean dry panel and report the average time. 3.2.10 Performance The product, used in accordance with manufacturers recommendations, shall remove normally accumulated soils from exterior surfaces of aircraft. No visible residue

35、shall remain on any surface tested. Standards for acceptance shall be as agreed upon by purchaser and vendor. 3.3 Quality The cleaner, as received by purchaser, shall be homogeneous, uniform in color, and free from skins and lumps and from foreign materials detrimental to usage of the cleaner. 4. QU

40、 and when purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing Shall be in accordance with ASTM D 1568; a lot shall be all cleaner produced in a single production run from the same batches of raw materials under the same fixed conditions and presented for vendors inspection

41、at one time. 4.4 Approval 4.4.1 Sample cleaner shall be approved by purchaser before cleaner for production use is supplied, unless such approval be waived by purchaser. Results of tests on production cleaner shall be essentially equivalent to those on the approved sample. 4.4.2 Vendor shall use ing
