MIL-V-62358(AT)
3.5.7.2 High temperature. After submersion in oil conforming to MIL-L-21260, Grade 30 which conforms to MIL-L-2104, Grade 30 oil with 135 to 270 ppm biocide, at 300 + 100F for
24 hours, valve shall open at not more than 18 volts at which time pressure in a cavity between orifice and valve shall not exceed 18 psi. Valve shall close when voltage is reduced to not less than 1 volt at which time pressure in a cavity between orifice and valve shall be not less than
80 psi. Assembly shall meet the requirements of 3.5.1 through 3.5.5, following which assembly lead wire shall withstand a 180 + 50 bend around a 0.75 + .02 inch diameter arbor without cracking (see 4.6.7.2).
3.5.7.3 Thermal shock. Assembly shall withstand 15 thermal shock cycles of a non-energized soak of not less than 2 hours at -60 + 50F and a soak of not less than 1 hour at 300 + 50 F while energized with +30 + 1 volt, following which assembly shall meet requirements of 3.5.1 through
3.5.5 (see 4.6.7.3).
3.5.7.4 Basic shock. Assembly shall meet requirements of 3.5.1 through 3.5.5 after exposure to shock impulses of 30 + 3g, at 11 + 1.1 milliseconds (ms) half sine wave applied in each direction of 3 mutually perpendicular axes (see 4.6.7.4).
3.5.7.5 Gun firing shock. Assembly shall meet requirements of 3.5.1 through 3.5.5 after exposure to gun firing shock of 55 + 5.0g for 2.5 + 0.2 ms duration applied along equivalent transmission transverse and longitudinal axis (see 4.6.7.5).
3.5.7.6 Sinusoidal vibration. Assembly shall meet the requirements of 3.5.1 through 3.5.5 after exposure to sinusoidal vibration in accordance with figure 1 in each of three mutually perpendicular axes. Vibration shall be imposed at a logarithmic sweep rate of 12 + 1 minutes per sweep cycle from 7 to 2700 to 7 hertz (Hz), for 28 sweep cycles in each of three mutually perpendicular axes. An equal number of sweeps will be made, both energized to +30 + 1 volts and de-energized, along each axis (see 4.6.7.6.1).
3.5.7.7 Random vibration. Assembly shall meet the requirements of 3.5.1 through 3.5.5 after being subjected to 100 hours of random vibration durability testing in any one of three mutually perpendicular axes. Test conditions shall be as specified in the random vibration spectrum curve in figure 2. Assembly shall be energized with +30 + 1 volts and cycled at a rate of 15 minutes on and 15 minutes off. Test may be performed at room ambient conditions (see 4.6.7.6.2).
3.6 Identification and marking. Identification and marking shall be in accordance with
MIL-STD-130 and as noted on Drawing 12288178.
3.7 Workmanship. Workmanship shall meet all specified requirements and shall assure that solenoid valve assemblies are free of defects that would affect performance.
