4.4.4 Tests. Test shall be conducted as follows:
(a) In-line pressure check qauge assembly. The assembly shall be
s~.ejected to a minimum of 200 psig air pressure for a minimum period of one
minute and observed for leakage. Check for leakage with a suitable leak detect-
ing solution (see 6.3).
(b) Pressure check gauge assembly. The assembly shall be subjected
to a minimum 2100 psig air pressure. Stabilize the pressure and "top-off" to
2100 psig minimum. Check for leakage with a suitable leak detecting solution.
If leakage is observed through the air vent, observe the gauge for one minute
minimum and record the pressure drop (see 6.3).
5.1 Cleaning. The components shall be cleaned, as neccessry, to be free of
foreign matter that would interfere with the satisfactory performance of, or
cause damage to the item. Cleaning shall be in accordance with cleaning pro-
cess C-1, and drying shall be in accordance withany of the drying procedures
outline in MIL-P-116.
Preservation and unit packing.
Level shall be as specified (see 6.2).
5.2.1 Level A.
18.104.22.168 Gauge assembly, in-line pressure check, 300 psig. The gauge,
cleaned in accordance with 5.1, shall have openings closed with plastic clo-
sures conforming to MIL-C-550l/7 and then wrapped in a piece of bound fiber
cushioning material whose dimensions in inches shall be 1 by 5 by 12 and con-
forming to type IV, class A of PPP-C-1120. The wrapped gauge shall then be
enclosed in a fiberboard box having inside dimensions in inches of 4-1/2 by
4-1/2 by 3 length, width and depth, respectively and conforming to W6C, style
RSC of PPP-B-636. The box shall be closed in accordance with method III or IV
of the appendix to PPP-B-636. The closed box shall then be sealed in a barrier
bag, size 8-3/4 by 10 conforming to type II, class E, style 1 of MIL-B-117.
The box shall be free of any projections or sharp edges or points that could
rupture or damage the barrier bag. Included air volume shall be kept to a
practicable minimum when the bag is sealed.
22.214.171.124 Gauge assembly, pressure check, 3000 psig. The gauge, cleaned in
accordance with 5.1, shall have openings closed with plastic closures conform-
ing to MIL-C- 5501/7 and then wrapped in a piece of bound fiber cushioning
material whose dimensions in inches shall be 1 by 7 by 12 and be placed in a
fiberboard box 7-1/4 by 4-1/2 by 3 inches inside length, width and depth respec-
tively, conforming to W6c, style RSC of PPP-B-636. The box shall be closed in
accordance with method III or IV of the appendix to PPP-B-636. The closed box
shall then be sealed within a barrier bag, size 8-3/4 by 12, conforming to type
