Each bag shall contain this printing on at least one su
23、rface 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 th
24、e 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 recommendations. 3.6.1 Heat sealing (Type I only). Each unit package of bags shall include a sheet legibly marked with the following heat
25、-sealing information. a. Jaw type sealer (temperature, pressure, and dwell time). b. Band type sealer (temperature, pressure, and dwell time). c.

VERIFICATION 4.1 Classification of inspections. The inspection requirements specified herein are classified as follows: a. First article inspec
28、tion (see 4.2). b. Conformance inspection (see 4.3). 4.2 First article inspection. First article inspection shall consist of all the tests and examinations specified in this specification. 4.3 Conformance inspection. Conformance inspections shall consist of the seam (seal) strength test specified in

32、and 18 1 ounces for Type II bags. At least one specimen taken from each sealed seam shall be tested from each bag sampled. Specimens shall be 1 inch wide with length dependent upon bag size. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
33、 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 Points
34、 packaging activities within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-22020E 6 from the managing Military De
35、partments or Defense Agencys 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 specificati
36、on are intended for use in specialized military methods of preservation where VCI treated sealable bags are required. Barrier materials used in the construction of these bags are military unique and the bags provide the necessary protection to their contents from exposure to the extremes of the navy
37、/naval aviation environment. There are no commercial equivalent materials that can provide this protection. Bags meeting the requirements of this specification are one of the building blocks approved under MIL-STD-2073-1 to provide the unique protective properties required to protect military hardwa
38、re from exposure to the severe military operating environment. 6.2 Acquisition requirements. Acquisition documents must specify the following: a. Title, number, and date of this specification. b. Type of bag (see 1.2). c. Size of bags (inside length and width dimensions) (see 3.4). d. If first artic
39、le inspection is required (see 4.2). e. Packaging requirements. 6.3 Lot size. Inspection lot will consist of all bags manufactured by the same process from the same raw material during one production run. 6.4 Material Safety Data Sheets (MSDSs). Contracting officers will identify those activities re
40、quiring copies of completed Material Safety Data Sheets prepared in accordance with FED-STD-313. The pertinent Government mailing addresses for submission of data are listed in FED-STD-313; and 29 CFR 1910.1200 requires that the Material Safety Data Sheet for each hazardous chemical used in an opera
41、tion must be readily available to personnel using the material. Contracting officers will identify the activities requiring copies of the Material Safety Data Sheet.
