4.5 Methods of inspection.
4.5.1 Pull and elongation. The link shall be assembled to
the test fixture and subjected to the pull load specified on Dwg.
8447633 or 12910231. The distance, x-x, shall be measured and
recorded. Observation shall be made for compliance with the
applicable drawing requirement. The load shall then be increased
at a uniform rate to that specified on Dwg. 8447859. The full
load shall be removed and the pull load specified on Dwg. 8447633
or 12910231 reapplied. The distance x-x shall be remeasured and
recorded. Observation shall be made for compliance with the
permanent set requirement specified on the applicable drawing. In
addition, observation shall be made for link fracture. Upon
completion of the test, links so tested shall be scrapped.
4.5.2 Decarburization.
The cross section of the sample short
and long loops shall be polished, etched with 3 to 5% Nital
solution and examined under a microscope of not less than 500
power. Observation shall be made for compliance with the
applicable drawing requirement.
4.5.3 Salt spray. Salt spray testing shall be conducted in
accordance with ASTM Method B117. Observation shall be made for
compliance with the applicable requirement in DOD-P-16232.
4.5.4 Hardness. Hardness testing shall be conducted in
accordance with ASTM Method E18. Observation shall be made for
compliance with the applicable drawing requirement.
4.5.5 Tensile load. The sample links shall be assembled into
belts of five (5) links each using three (3) dummy cartridges and
the two (2) specified mandrels. The assembled belt shall be
placed in the test fixture and subjected to the applicable tensile
load. There shall be no belt separation. Upon removal of the
