4.5.2.7.1 Failure criteria. Nonconformance to 3.11 shall constitute failure
of this test.
4.5.2.8 Slinging attachments.
4.5.2.8.1 Test procedures.
a. Lift the paver and hold in suspension in its normal travel position
using slings that converge not more than 24 feet above the lowest
extremity of the paver. Determine the true angle of each sling leg
relative to the vertical. Measure the clearance between each sling
and the paver.  Measure eye openings and clearance dimensions of the
attachments.
b.  Restrain the paver by anchoring the main frame and subject each
provision to a force equal to the load factor specified in MIL-STD-209
times the load it carried in a. above. An alternate method of test is
to lift the paver as in a. above and add weights to the main frame
until the required force is obtained. Hold the paver under either of
the above loading conditions for at least 90 seconds.
4.5.2.8.2 Failure criteria. Weld failure or permanent deformation caused by
lifting or failure to meet requirements of MIL-STD-209, shall constitute failure
of this test.
4.5.2.9 Equipment tiedown attachments.
4.5.2.9.1 Test procedure.  With the paver anchored by means other than the
attachment being tested, apply the proportion of the static loads as specified
in MIL-STD-209 to each attachment. Measure dimensions of the tiedowns.
4.5.2.9.2 Failure criteria. Failure to meet the requirements of MIL-STD-209
shall constitute failure of this test.
4.5.2.10 Rail impact test.  When required (see 6.2), the paving machine shall
successfully complete a rail impact test as specified in Appendix A of
MIL-STD-1186.  After each impact, the paver shall be inspected for permanent
deformation of its components, or other evidence of possible failure. After
completion of the railroad impact test, an operational checkout of the paver
will be conducted.
4.5.2.10.1 Failure criteria. Weld failure or permanent deformation of the
paver components or its tiedown attachment, or failure of the paver to operate
after the test shall constitute failure of this test.
