4.5.2.6.1 Test Procedures.
a.
Lift the spreader and hold in suspension in its normal travel position
using slings that converge not more than 24 feet above the lowest
extremity of the spreader. Determine the forward angles of applica-
tion for each provision. Measure the clearance between each sling and
the spreader. Measure eye opening and clearance dimensions of the
provision. Measure the load carried by each provision.
b.
Restrain the spreader by anchoring the main frame and subject each
provision to a force equal to the load factor specified in MIL-STD-209,
for type II equipment, class 1 and 3 provisions times the load it
carried in a. above. An alternate method of test is to lift the
spreader as in a. above and add weights to the main frame until the
required force is obtained. Hold the spreader under either of the
above loading conditions for at least 90 seconds.
4.5.2.6.1.1 Failure criteria. Weld failure or permanent deformation caused
by lifting or failure to meet the requirements of MIL-STD-209, for type II
equipment, class 1 and 3 provisions shall constitute failure of this test.
4.5.2.7 Tiedown provisions.
4.5.2.7.1 Test procedure. With the spreader anchored by means other than the
attachment being tested, apply the proportion of the static loads as specified
in MIL-STD-209, for type II equipment, class 2 and 3 provisions to each attach-
ment. Measure dimensions of the tiedowns.
4.5.2.7.1.1 Failure criteria. Failure to meet the requirements of MIL-STD-209,

constitute failure of this test.
