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 with 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
responsible packaging activity.

sensing instrumentation.
