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.
