21、IFICATION 4.1 Classification of inspections. The inspection requirements specified herein are classified as conformance inspection (see 4.2). 4.2 Conformance inspection. 4.2.1 Sampling for examination. Test samples shall be selected at random in accordance with ASQ Z1.4, with the sampling level as s
22、pecified in table I. The acceptance quality limit (AQL) shall be as specified in the contract or purchasing order (see 6.2). Identical sample items may be used for any of the tests, provided that selection of random samples is maintained and known characteristics of the samples are not used to influ
23、ence the integrity of the test results. TABLE I. Conformance examination. Test Reference paragraph ASQ Z1.4 sampling inspection level Inspection lot 4.2.2 - Examination 4.3.1 II Material certification 4.3.3 - Grip length break 4.3.4 II 4.2.2 Inspection lot. A lot shall consist of sleeves or grommets
24、 made from the same lot of material and fabricated as a single continuous production run in which the forming machine set-up remains unchanged except for head configuration. A lot shall be restricted to one sleeve or grommet diameter or material thickness. A lot of material shall be defined as the q
25、uantity of sheet or strip steel made from a single heat. It shall be controlled and shipped with appropriate mill certification. In addition, the manufacturer shall maintain a record of inspections by lot number for a period of three years. 4.2.3 Certified test report. The manufacturer shall furnish
26、 certification that the product conforms to this specification. The record shall state that the product meets all the requirements of this specification. 4.3 Examination and tests. 4.3.1 Examination.

27、 the requirements for dimensions, workmanship, identification, and to all requirements not covered by the tests. Samples failing to meet examination requirements shall result in rejection of the lot. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MI
28、L-DTL-85069D 5 4.3.2 Strength. The strength of the fastener sleeve or grommet combination is considered the strength of the fastener alone. The wall thickness of the sleeve or grommet is considered thin enough so that there shall be no material decrease in thickness when under load. Sleeve or gromme
29、t thickness shall be measured by any approved means. Sleeves or grommets that do not meet the dimensional requirements for thickness as shown in figures 1 through 4 shall result in rejection of the lot. 4.3.3 Material certification. Mill certification on all materials shall be kept on file by the ma
30、nufacturer and shall be available to the procuring agency for a period of three years. 4.3.4 Grip length break. Using different fastener sleeves, break at different lengths with the proper tooling. Grooved sleeves shall be broken only one time. To adjust to length at a location other than the breaki
31、ng area of the step plate, the sleeve may be ground to length using the painted section of the step plate. Sleeves that fail to break cleanly at the grooves shall result in rejection of the lot. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
32、 the contract or order (see 6.2). When 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 packa
33、ging activities within the Military Service 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 activ
