A sample of filled containers selected from each lot in accordance with MIL-STD-1916 as specified in the contract or
28、 order shall be examined to verify compliance with all stipulations of this specification regarding fill, closure, marking and other requirements not involving tests. Containers shall be examined for defects of the container and the closure, for evidence of leakage, and for unacceptable markings; ea
29、ch sample filled container shall also be weighed to determine the amount of the contents. Any container in the sample having one or more defects, or under required fill shall cause rejection of the container and if the number of defective containers in any sample exceeds the acceptable number for th
30、e appropriate sampling plan as specified in the contract or order, this shall cause rejection of the lot represented by the sample. 4.3.2.1 Examination of compound material. Portions of the compound material shall be taken from top, bottom and intermediate parts of the sample of containers and exami
31、ned visually to determine that there is no apparent difference in appearance or consistency. The material shall be homogeneous and show a smooth greasy consistency without lumps, crusts or granular particles. It shall not have an odor of rancidity or perfume. 4.3.3 Sample material for testing. From

The 5-pound sample specimen shall be retained by the manufacturer or contractor for verification testing, if required, at a later date. 4.3.4 Sampling for production check tests. Unless otherwise specified (see 6.2), from the first
33、lot produced on a contract or order and thereafter at such intervals as may be considered necessary by the command or agency concerned to verify the consistency of production quality, one 2-pound sample and two 1-pound samples of compound shall be forwarded to a laboratory acceptable to the command
34、or agency concerned. These samples shall meet the requirements of 3.6 and any other tests deemed necessary by the command or agency concerned to determine conformance of the product. 4.4 Tests. 4.4.1 Test procedures. The following tests shall be performed in accordance with Table I. TABLE I. Test me

36、. 4.4.2.1.1 Apparatus. The test apparatus shall consist of the following: A fixture made of carbon steel, using material in accordance with ASTM A 515, grade 70, 13 by 3 inches by approximately 1-1/2 inches thick for the end blocks which have 5 equally spaced holes, 13/16 inch in diameter, with surf
37、ace finish of 250 roughness height rating (RHR), to allow for insertion of inch 10 UNC studs (see Figure 1). The top and bottom faces of the steel end blocks shall have a surface finish of 250 RHR and be parallel within 0.002. Five unused coarse thread studs, in accordance with grade B16 of MIL-DTL-
38、1222, ASTM A 193 or equal, cut from the same length of a continuously threaded stud stock and ten unused nuts, in accordance with grade 4 of MIL-DTL-1222, ASTM A 194 or equal, shall be used for this test. Each stud shall be 12.000 0.125 inches long and shall have end surfaces which are perpendicular
39、 to the axis of the stud to a degree which shall allow stud length measurements of the required Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-907F 5accuracy. Two carbon steel face places in accordance with ASTM A 109, 13 by 3 inches and 0.1
40、25 inch thick with a surface finish of 62 RHR or smoother and five equally spaced holes to match those of the above described end blocks, shall be furnished for this test. Components for this test shall be as shown on Figure 1. A torque wrench shall be used which is easily readable, graduated in foo
41、t-pounds (ft-lb) and has a degree of accuracy of 5 percent. The overall length of each stud shall be measured with a dial indicator type device or equal, graduated in 0.0001 inch divisions, having an overall accuracy of 0.0001 inch. 4.4.2.1.2 Preparation. Dry-cleaning solvent shall be in accordance
42、with type I of MIL-PRF-680. Each component shall be cleaned in the dry-cleaning solvent and dried just prior to lubrication. The test equipment shall be assembled using the two plates as specified in 4.4.2.1.1. The threads of the studs and nuts shall be evenly coated with the antiseize compound as f
43、ollows: a. A liberal quantity of compound shall be applied to the studs and nuts. b. The nuts shall then be run to the ends of the studs (prior to assembly with the block). c. The excess compound shall be removed from the ends of nut travel on the studs and from the edges of the nuts after removal f
44、rom the studs. The block and plate shall be assembled with a stud in each of the five holes. The surface of the plates and the mating surfaces of the nuts shall be coated with a light coating of the antiseize compound. The nuts shall be run on to the studs, hand tight, against the plates. The overal
45、l length of each stud shall be measured to 0.0001 inch and recorded. 4.4.2.1.3 Procedure. The nuts shall be tightened until an elongation of 0.0162 0.0001 inch is obtained, which corresponds to a stress of approximately 50,000 pounds per square inch (PSI) at the root area of the stud thread. The tor
46、que required for each nut and stud tightening shall be recorded. The test block assembly shall be placed in an electronically heated oven and subjected to 1050 + 10 - 0F for 6 hours. Then the assembly shall be removed from the oven and allowed to cool to room temperature. The breakaway torque to loo
47、sen the nuts shall be measured and recorded. The length of the studs shall be measured. The nuts shall be tightened to re-establish the elongation of the stud length (that is, 0.0162 0.0001 inch) and the torque required recorded. The heating, cooling, torque measurements, and stud length measurement
48、s shall be repeated. Then for the third time the assembly shall be heated, cooled and subjected to a spray of 20 percent aqueous solution of sodium chloride for 7 days. At the end of this period, the assembly shall be removed and allowed to dry at room temperature for 24 hours. The torque required t
49、o loosen the nuts shall be determined and recorded. The condition of the threads and other contact surfaces, seizing of the nuts and shearing of the studs shall be noted and properly recorded. A five-point check of the torque wrench calibration against another calibrated wrench at 150 ft-lb shall be made prior to torquing and untorquing each assembly. If the torque wrench is dropped or otherwise damaged during its use, its calibration shall be c
