Each bag shall contain this printing on at least one surface with the color and position of the printing being optional. When the marking is interrupted or incomplete due to the size of the bags, the individual bag need not be marked as specified, but shall be accompanied within the shipping container by an identification sheet marked or printed with the same information. When specified (see 6.2), a pressure sensitive label shall be applied to the outer surface of each bag in lieu of marking the bag.

3.6 Sealing recommendation. Each unit package of bags shall include a sheet legibly marked with the following heat-sealing information.

For the purpose of determining the sample size in accordance with ASQ-Z1.4, the lot size (see 6.3) shall be expressed in number of bags produced in one production run and shall use an inspection level of S-1 for testing and S-3 for visual examination. There shall be no failures.

The sample unit for the end item visual inspection shall be one bag. The sample unit shall be visually inspected and measured to ensure it meets the requirements specified in 3.2, 3.3, 3.3.1, 3.4, 3.5, 3.6, and 3.8.

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 personnel 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.

6. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1 Intended use. Bags covered by this specification are intended for use in specialized military methods of preservation. The barrier materials, from which these bags are constructed of, are all approved and military unique and provide the necessary requirements for protection from exposure to the extremes of the navy/naval aviation environment. There are no commercial equivalents that meet the requirements necessary to protect materiel that is exposed to the operational naval aviation environment. Specifically, Methods of Preservation 31, 32, 33, 41, 42, 51, and 52 utilize these bags in order to provide the specialized military preservation required by MIL-STD-2073-1.

6.1.1 Class B bags. Class B bags are intended for preserving items that require waterproof protection as specified in MIL-STD-2073-1, Method 31and Method 32.

6.1.2 Class C bags. Class C bags are intended for preserving items that require greaseproof protection in addition to waterproof protection as specified in MIL-STD-2073-1, Method 33.

6.1.3 Class E bags. Class E bags are intended for preserving items that require watervaporproof, waterproof, and greaseproof protection as specified in MIL-STD-2073-1, Method 41, 42, 51, and 52.

6.1.4 Class F bags. Class F bags are intended for preserving electrostatic discharge sensitive items. They also provide electromagnetic interference and electrostatic shielding protection. Additionally, these bags provide the watervaporproof protection as specified in MIL-STD-2073-1, Method 41 and Method 51.

6.1.5 Class H bags. Class H bags are intended for preserving electrostatic discharge sensitive items.

6.2 Acquisition requirements. Acquisition documents must specify the following:
