For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). Wh
27、en packaging 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 De
28、partment or 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. 6. NOTES (This section contain
29、s information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. In addition to the notes specified herein, the notes specified in MIL-PRF-39009 are applicable to this specification. 6.2 Acquisition requirements. Acquisition documents must specify the fo
30、llowing: a. Title, number, and date of this specification and the complete PIN (see 1.2). * b. Unless otherwise specified (see 2.1), the versions of the individual documents referenced will be those in effect on the date of release of the solicitation. c. Packaging requirements (see 5.1). 6.3 MIL-R-
31、18546/1 substitution data. Resistors of this specification, regardless of their failure rate (FR) designation, are substitutes for resistors of the same resistance value and characteristic G as specified in the inactivated specification MIL-R-18546/1 as in accordance with table VIII.

36、0 watts from the previous 15 watt rating is based on qualification of similar style RE70 under MIL-PRF-18546. In addition, the accumulated FR component hours at 15 watts have been halved for qualification FR level retention. Until sufficient hours are established at 20 watts, the Qualified Products
37、List will continue to list FR levels at the previous 15 watt rating, and in addition, the FR level at the 20 watt rating * 6.6 Changes from previous issue. The margins of this specification are marked with asterisks to indicate where changes from the previous issue were made. This was done as a conv
