17、130“ + 5“F, for a minimum period of 4 hours, without evidence of deterioration or damage that may impair its intended operation. While at the high temperature (at the end of the high-temperature exposure period), the door bolt assembly shall comply with the functioning requirements of 3.4. Testing s

18、hall be specified in 4.5.3. 3.7 Low temperature. The door bolt assembly shall withstand a low temperature of -15“ + 3F for a minimum period of 4 hours, without evidence of dekerioration or damage that may impair its intended operation. While at the low temperature (at the end of the low-temperature

19、exposure period), the door bolt assembly shall comply with the functioning requirements of 3.4. Testing shall be as specified 4.5.4. 3.8 Humidity. The door bolt assembly shall withstand a relative humidity of 95 + 5 percent and a temperature of 130“ - + 5F without evidence of Corrosion and without e

20、vidence of deterioration or damage that may impair its intended operation. After this test (at room temperature), the door bolt assembly shall comply with the functioning requirements of 3.4. Testing shall be as specified in 4.5.5. -3.9 Detent loadinq. The door bolt assembly shall withstand a load o

21、f 10,000 pounds, applied axially to the end of the extended bolt, for a minimum period of 30 seconds, without damage or evidence of detent failure. Testing shall be as specified in 4.5.6. 3.10 Workmanship. All parts and accessories shall be constructed, assembled, and finished in a thoroughly workma

First article inspection (see 4.3) b. Quality conformance inspection (see 4.4) 4.3 First article inspection. 4.3.1 Submission. When th

27、e contract requires first article inspection, the contractor shall submit three consecutively produced door bolt assemblies to the testing facility designated in the invitation for bids or request for proposal. 4.3.2 Inspection and testing to be performed. The first article inspection samples shall

28、be inspected for the defects specified in 4.4.2.1, using inspection methods contained therein, and for all the requirements of Section 3. The test requirements of Section 3 are listed in Table I, and the door bolt assemblies shall be tested using the test methods specified in 4.5. Inspection and tes

29、ting shall be performed with the acceptance inspection equipment specified in 4.4.4. The door bolt assemblies shall be tested in the order specified in Table I. If any door bolt assembly fails to comply with any of the applicable requirements, the first article samples shall be rejected. The Governm

30、ent reserves the right to terminate its inspections upon any failure of the first article samples to comply with the stated requirements. This series of tests is considered destructive, and samples so tested shall not be returned to the lot. TABLE I. First article tests. Requirement Test Paragraph a
