The threaded fasteners used to

46、secure the test weights shall be tested. Test fixtures shall be fashioned to evaluate thesheltersshelters ability to securely hold threaded fasteners (10-32(1032 through 1/2-2012 20 bolts). The test fixtures shall befashioned to induce only a twisting load to the shelter attachment point for the tor

Reaction forces applied by the pull-out test fixture ontothe shelter surface shall be outside a 3 in. (7.6 cm) radius measured from the center line of the fastener being t

48、ested. Failure tomeet the requirements of 3.2.3.3 shall constitute failure of this test. In addition to sample panel testing, the Contractor will selecta total of 50 test weight inserts on the primary FirstArticle Test Unit and conduct both an Initial and Final Torque Test and Pull-outTest on each o

49、f the 50 inserts selected as part of First Article Testing. The Government shall approve the Contractors selectionof test inserts prior to the start of any testing.(1) TorqueTo determine compliance, a torque load equal to 8 ft-lb (1.11 kg-m) for the 10-32 bolt and 10 ft-lb (1.38 kg-m),for the other bolts shall be applied to all fasteners installed in the shelter, fasteners used to integrate the system (see 4.2.3.3) shouldbe used wherever possible. Failure to meet the torque requirements of 3.2.3.3 shall constitute failure of this test.(2) Pu
