The testing machine shall be capable of applying a compressive load at a controllable rate. The calibrating system for the machine shall conform to MI
24、L-STD-45662. Its accuracy shall be verified every 12 months by a method complying with ASTM E4, using a calibration device which has been calibrated by the National Bureau of Standards not more than 2 years prior to its use. The loads of the fasteners tested shall be within the range of the testing
25、machine as defined in ASTM E4. 4.1.2 Test fixtures. Test fixtures shall be in accordance with Figure 1. 4,1.3 Grin IenHh. Unless otherwise specified, the minimum grip length of the test specimen shall be 3D. 5. DETAIL REQUIREMENTS 5.1 Test nrocedures. The ultimate double shear strength shall be obta
26、ined as follows: 5.1.1 Test Fixture. The fastener is placed in the receiving half-holes of the fixture base with neither threads nor fillet in bearing. 5.1.2 Test mecimen. The blade (guillotine) portion is placed in position on the specimen and the preload applied. 5.1.3 Load rates. The test loadis
27、then applied at a uniform rate as specified in table I. Load rates for larger or smaller size fasteners shall be calculated to give an initial stress rate of 100,000 pounds per minute per square inch of nominal double shear area. A tolerance of f 10 percent shall apply on the load rate. The nominal
28、double shear area is twice the nominal shank area for the load rate calculation i only. The test may be discontinued the ultimate load has been reached. and the specimen removed without a complete shear failure after SHEET 5 APPROVAL DATE AUGUST 1997 USE OF OR RELIANCE UPON THIS DOCUMENT OR ANY AERO
