MIL-DTL-22606D(SH)
4.4.2 Pressure tests. In the event a flask fails the hydrostatic test specified in 4.3.3.1, the manufacturer may
apply to the contracting activity for a one-time reheat treatment and retest. If the reheat treatment and retest are
approved by the contracting activity, the flasks shall be reheat-treated in accordance with 3.3.3 and retested as
specified in 4.3.3.1. Flasks failing the gas leakage test shall have the defective O-ring seal area or seal weld
repaired, recoated, and the flask retested as specified in 4.3.3.2.
4.4.3 Nondestructive and visual inspection. Surface imperfections detected by the methods specified in 4.2 or
4.3.4 which would require rejection but can be made acceptable by grinding, machining or cleaning, may be so
treated and then reexamined by the same method as that which disclosed the imperfections.
4.5 Mercury contamination test. In the event of suspected mercury contamination or lack of mercury-free
material certifications as specified in 3.1.8, testing shall be conducted to determine if excessive mercury
contamination is present. Surface and internal contamination shall not exceed 0.01 milligram per cubic meter. The
flask shall be pressurized, and a gas sample collected. The procedure to conduct such a sample, sampling/analysis
devices, and acceptance criteria shall be approved by NAVSEA prior to conducting the test (see 6.2). If
contamination testing is conducted, documentation stating test methods and test results shall be provided in lieu of a
mercury-free material certification.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or
order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these
personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging
requirements are maintained by the Inventory Control Point's packaging activities within the Military Service or
Defense Agency, or within the military service's system commands. 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 responsible packaging activity.
