the rated pressure for 1 minute. Under the hydrostatic pressure, the fitting
shall not leak water or sweat at any part of the surface.
4.3.2 Air pressure leakage test. Each flange shall be tested under
water or with soapsuds at 100 pounds per square inch (lb/in2) (nominal) air
pressure (85 lb/in2 minimum) for 5 to 10 seconds. No leakage is allowed.
4.3.3 Chemical analysis. Each sample flange selected as specified in
4.1.4 for chemical analysis shall be tested in accordance with ASTM E172 or
ASTM E1282 to determine conformance to 3.1.

PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements
shall be as specified in the contract or order (see 6.2). When actual
packaging of material is to be performed by DoD personnel, these personnel
need to contact the responsible packaging activity to ascertain requisite
packaging requirements. Packaging requirements are maintained by the
Inventory Control Point's packaging activity within the Military Department or
Defense Agency, or within the Military Department's System Command. Packaging
data retrieval is available from the managing military Department's or Defense
Agency's automated packaging files, CD-ROM products, or by contacting the
