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.
