Each specimen shall be stressed by applying a load equivalent to 45 percent of notch fracture strength. The notch shall be immersed in the cleaner for the duration of the test. Discontinue the test if
41、 no fractures occur after 150 hours of immersion. If a failure occurs in one of four specimens tested, a second set of 4 specimens shall be evaluated. A minimum of 7 out of 8 specimens shall meet the 150 hour duration. 4.5.7 Effect on polyimide insulated wire. Approximately 24 in. (61 cm) of wire co
42、nforming to MIL-W-81381/11 shall be formed into a coil. Place the coil in a 4 ounce (118 ml) wide mouth jar. Add to the jar sufficient cleaner to completely cover the coil of wire. Cap the jar and store it at room temperature for 14 days. Concurrently, perform this procedure using distilled water fo
43、r comparison. At the end of the storage period, remove both coils and rinse thoroughly with tap water at room temperature. Suspend each coil and allow it to drain until completely dry. Each wire shall then be uncoiled and wrapped tightly on a 0.125 in. (3 mm) mandrel noting the appearance of any cra
44、cks in the insulation. Each wire shall then be unwrapped and rewrapped in the opposite direction, again noting appearance of cracks. If the test wire shows no more cracks than the comparison wire, it shall be immersed in a 5 percent by weight sodium chloride solution and subjected to a one minute di
45、electric test of 2,500 volts (root mean square) without breakdown or leakage in accordance with ASTM D3755.

46、de sealants shall be determined as specified in 4.5.8.1 and 4.5.8.2. 4.5.8.1 Preparation of test specimens. Sealants in accordance with MIL-PRF-81733, Class 1, Grade B, Type II and AMS-S-8802, Class B shall be mixed as specified by their respective manufacturers and pressed into 1/8 inch thick sheet
47、 molds. Sealants shall be cured for 14 days at 77 5 F (25 3 C) at 50 percent humidity or an accelerated cure for 48 hours minimum at standard conditions followed by 48 hours at 140 F (60 C). The cured sealants are the sheet stock from which the specimens for each sealant shall be cut. 4.5.8.2 Test p
48、rocedure. The Shore A hardness of each sealant specimen shall be measured as specified in ASTM D2240 (stacking two specimens of the same sealant to make a -inch thickness) before exposing it to the cleaner. Two specimens of each sealant shall be immersed in cleaner at room temperature. After 30 minu
49、tes, specimens shall be removed, wiped dry and tested (as above) within 30 minutes for Shore A hardness. 4.5.9 Cleaning efficiency. 4.5.9.1 Preparation of test specimens.
