13、ection. When specified (see 6.2), samples shall be subjected to conformance inspection in accordance with 4.2. 3.2 Design and construction. 3.2.1 Construction. The fastener sleeve or grommet shall be drawn from sheet or strip stock to form a one-piece tubular section and head. The thickness of the t
14、ubular wall and head shall be uniform. Sleeve tubular sections shall be grooved in 0.062-inch increments to aid in adjusting the sleeve to the desired length. 3.2.2 Material. Sleeve and grommet material shall conform to UNS S66286 corrosion and heat-resistant steel in accordance with SAE AMS 5525 (s
15、ee 4.3.3). 3.2.3 Head structure and grain flow. When visually examined, the sleeve or grommet may show axial grain flow lines in the tubular section typical of a drawn sleeve or grommet. The flow lines shall be continuous at the fillet radius. 3.2.4 Protective coatings. The fastener sleeves and grom
16、mets shall be passivated in accordance with SAE AMS2700. 3.2.5 Lubrication. The fastener sleeves and grommets shall be lubricated with cetyl alcohol or left bare. Cetyl alcohol, if used, shall conform to SAE AS87132. Packaging shall be marked as shown to indicate use or non-use, as indicated: L - lu
17、bricated with cetyl alcohol B - no lubrication 3.2.6 Surface texture. Surfaces shall be free of cracks or draw marks; slight visible orange peeling effect shall be permitted. Unless otherwise specified (see 6.2), grommet surface texture shall be not more than 125 microinches in accordance with ASME
18、B46.1. 3.2.7 Shape. Fastener sleeves and grommets shall be round and shall show no evidence of distortion. 3.2.8 Grip length. Grooved sleeves or non-grooved grommets may be procured at the required length. Alternatively, grooved sleeves may be broken at incremental lengths using the proper tooling .
19、 The step plate tool indicates the grip length at which the sleeve will break along the groove without damage to the sleeve. 3.3 Metallurgical properties. 3.3.1 Cracks. The fastener sleeves and grommets shall be free of cracks. A crack is identified as a clean crystalline break passing through the g
20、rain or boundary without the inclusion of foreign elements. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-85069D 4 3.3.2 Discontinuities. There shall be no laps or folds, seams or discontinuities, or other interruption in grain flow. 4. VER
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
