Cross sections of forged c

17、omponents may be cut unsymmetrical or out of round due to die mismatch, flash trim, and cleaning processes. The cross section contour, at any point, shall be within the maximum and minimum material condition limits set by the dimensions and tolerances specified. 3.4.2 Heat treatment. Forged clevis c

18、omponents shall be heat treated as specified in the applicable standard. Shall be heat treated to AMS2759, unless otherwise specified. 3.5 Finish. 3.5.1 Surface defects and roughness. Forged components shall be free from scale, burrs, sharp edges, fins, cracks and laps. Forging flash shall be remove

19、d substantially flush with the adjacent surfaces. Surface roughness shall not exceed values specified in the applicable standard. 3.5.2 Protective finish. Unless otherwise specified (see 6.1), the protective finish for metal components shall be as specified in the applicable standard. 3.6 Performanc

20、e. Clevises shall be capable of withstanding proof loads specified in the applicable standard without developing any evidence of failure, visible permanent deformation or defects that would interfere with disassembly when tested in accordance with 4.3.4. 3.6.1 Functional performance. The hardware sh

21、all meet all functional test and assembly requirements specified in the applicable standard. 3.7 Marking for identification. Each clevis body shall be marked, for identification, with the part number and the manufacturers name or readily identifiable trademark. Forged clevis pins shall be marked wit

22、h the part number only. The marking shall be the size, and in the Page 3 of 6 Copyright Protected: Do Not Copy!PIA-DTL-40137C location, shown in the applicable standard. The manufacturer may, at their option, utilize either raised or indented marking. If raised marking is used, the height of the cha

23、racters shall be sufficient to insure legibility but shall not exceed 0.02 inches. 3.8 Workmanship.

When required (see 6.1), examination of the first article samples for defects shall be as specified in 4.3.1 and 4.3.3 and testing of the first article samples for proof load shall be as specified in 4.4.1. The presence of any defect (see TABLE I) or failure of the proof load test shal

26、l be cause for rejection of the first article. 4.3 Conformance inspection. Unless otherwise specified (see 6.1), sampling for conformance inspection shall be performed in accordance with RR-C-271. The level of inspection of the lot shall be as specified (see 6.1) and to level S-4 per ANSI-ASQ Z1.4,
