For acquisition purposes, the packaging requirements shall be as s

40、pecified in the contract or order (see 6.2). When actual packaging of materiel 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 Points

41、packaging activity within the Military Department of Defense Agency, or within the Military Departments System Command. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packagi

42、ng activity. 6. NOTES (This section contains general or explanatory information that may be helpful, but is not mandatory .) 6.1 Intended use. The radiators covered by this specification are intended for use in the engine coolant systems of the vehicle classified (see 1.1). The radiator covered by t

43、his specification is military unique due to the vibrations it must be designed to endure. The vibrations resulting from the howitzer recoil and vehicle operation in battlefield temin are more severe than a commercially available radiator would be able to successfully sustain. 6.2 Acquisition require

44、ments. Acquisition documents must spec* the following: a. Title, number and date of this specification and any amendment. b. Issue of the DoDISS to be cited in the solicitation, and if required, the specific issue of documents referenced (see 2.2 and 2.3). c. When first article is required (see 3.1,

45、4.1.1 and 6.4). d. Any sampling for inspection to be utilized (see 4.1.2). e. What conformance verification is necessary (see 4.1.2 and 6.5). f. Packaging requirements (see 5.1). g. Any deviation from this specification. 6.3 Supersession data. When reviewing this document for changes, the previous r

46、evision “A” should not be used, as revision “A”, dated 17 March 1989 was erroneously issued covering the radiator specification for the M2 and M3 vehicles, Any comparison of this document should be made against the base specification, MIL-R-62259(AT), dated 28 September 1980. 6.4 First article. When

47、 requiring a first article inspection, contracting documents should provide specific guidance to offerors. This guidance should cover whether the rst article is a first article sample, a production item, or the number of items. These documents should also include specific instructions regarding arra

48、ngements for examinations, approval of first article 16 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-NIL-PRF-62259B 9999906 2069247 751 m MIL-PW-62259B test results, and disposition of first articles. Re-solicitation documents should provide Gover

49、nment waiver rights for samples for first article inspection to bidders offering a previously acquired or tested product. Bidders offering such products who wish to rely on such production testing must furnish evidence with the bid that prior Government approval is appropriate for the pending contract. 6.5 Conformance inspection.
