MIL-DTL-18295F
4.6.9.2 Microstructure examination in other areas of components. A test specimen, as stated in
table IV, shall be prepared and etched according to the metallographic procedure recommended in
ASTM E 3 and ASTM E 407. If grain size is greater than the limits of ASTM E 112 No. 6, using
the comparison method at 100X magnification, the represented components shall be rejected.
However, randomly dispersed grains as large as ASTM E 112 No. 4 are permissible. Test
specimens are to be taken from locations shown on figures 13, 14, 15, and 16 (see 3.4.4).
4.6.10 Macrostructure examination. For both cast and forged components, a test specimen shall
be prepared in accordance with ASTM E 3. Specimens shall be taken in the weld area and high
stress area. All samples shall be etched in accordance with ASTM E 340 and tested in accordance
with ASTM E 381. The test specimen must meet the requirements of MIL-STD-1265,
radiographic grade C or the represented components shall be rejected. Cast swivel shackles and
spider plates shall be 100 percent radiographically inspected from the location shown on figures
14 and 15. Other cast component specimens shall be 100 percent radiographically inspected.
Test specimens shall be taken from the finished product as given in table IV and shall meet the
requirements of 3.4.5.
4.6.11 Assembly test. All joining links shall be disassembled after the specified proof load,
examined for any defects and sharp corners, and then reassembled. Any joining links which have
sharp corners, defects, or cannot be disassembled and reassembled after the proof load shall be
rejected. Inspection of the tapered pins shall be conducted for any surface deformations after the
proof loading. If any defects are found, the tapered pin shall be replaced with a new one. Lead
plugs shall fill the cavity flush to the exterior surface after being expanded by hammering. Split
keys and tapered pins shall fit properly (see 3.3.4). Proper mating of components to the swivel
shall be determined (see 3.3.7). Shackle pins shall fit properly (see 3.3.7.2).
4.6.12 Marking. Marking shall be inspected for conformance with 3.8 through 3.8.2.
4.6.13 Finish. Inspect finish to determine compliance with 3.9.
4.7 End item inspection requirements. Government acceptance shall be dependent on successful
completion of the inspection (see 6.7.2).
4.8 Disposition of chain specimens. Unless otherwise specified (see 6.2), all mooring assembly
component break test specimens shall be retained at the manufacturing facility until completion of
the contract, at which time all specimens are to be destroyed.
4.9 Workmanship. Inspect workmanship to determine compliance with 3.10.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD
personnel, these personnel need to contact the responsible packaging activity to ascertain requisite
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
