Precondition resistors in an oven at 125OC 5OC for 13 minutes 2 minutes, or use a fluorocarbon bath maint
31、ained at 125OC 5OC for a period of 1.5 minutes 0.5 minutes. Upon completion of precaution, allow resistors to stabilize to room temperature for approximately 13 minutes 2 minutes. b. Fluorocarbon. Immerse resistors (not to exceed 30 samples) into a bath of fluorocarbon held at 85OC +5OC, -0OC for a
32、period of 60 seconds 5 seconds. Visually examine resistors for inadequate seals, as evidenced by bubbles emanating from any point on the resistors. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packagin
33、g 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 Points packaging activity within the Military Department or
34、 Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
