NOTES (This section contains information of a general or explanatory nature which may be
32、 helpful, but is not mandatory.) 6.1 Intended use. The engines covered by this specification are intended for the M809 and M939 series 5 ton trucks used by the United States Military Service in transporting personnel or cargo, towing trailers or semitrailers, and recovering disabled equipment during
33、 military operations. The engines are military unique because they are specially designed to interface with the M809 and M939 trucks where no known commercial equipment can be substituted. 6.2 Acquisition requirements. Acquisition documents must spec the following: a. b. C. d. e. f 8- Title, number,
34、 and date of this specification. Engine classification (see 1.2 and 3 2.1).

36、d as follows: Vehicle used on designation M809 - Chassis, Truck, 5 Ton, 6x6 M939 - Chassis, Truck, 5 Ton, 6x6 Specification number Prefix for military specification 6.4 First article. When requiring a first article inspection, contracting documents should provide specific guidance to offerors. This
37、guidance should cover whether the first article is a first article sample, a first production item, or the number of test items. These documents should also include specific instructions regarding arrangements for examinations, approval of first article test results, and disposition of first article
38、s. Pre-solicitation documents should provide Government 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 Governm
39、ent approval is appropriate for the pending contract. 6.5 Conformance inspection. Mordable conformance inspection with confidence varies depending upon a number of procurement risk factors. Some of these factors include: Contractor past performance, Government schedules and budget, product material
40、and design maturity, manufacturing capital equipment and processes applied, the controlled uniformity of those processes, labor skill and training, and the uniformity of measuring processes and techniques. During the solicitation, contracting documents should indicate those tests desired from table
41、II and their designated frequency based on a risk assessment for the procurement. 6.6 Definitions. The following definitions shall be used for the classification of defects for leaks: a. Class I. Leakage indicated by wetness or discoloration not great enough to form b. Class II. Leakage geat enough
42、to form drops but not enough to cause drops to c. Class III. Leakage great enough to form drops that fall from the item being drops. drip from item being checkedinspected. checkedinspected. 17 Licensed by Information Handling ServicesHIL-DTL-bZ483A H 0b 2074878 Lb2 MIL-DTL-62483 A(AT) 6.7 Subject te
