TwO nozzles shall be directed downward toward the top of the asphalt melter.
One of these nozzles shall be directed toward a point on the longitudinal
.
centerlined of the melter, 2 feet from the drum entrance end of the tunnel, and.
the other nozzle shall be directed toward a point on the longitudinal centerline
of the melter, 2 feet from the discharge end of the tunnel. The nozzle
directional centerline of each of these nozzles shall be perpendicular to the
top of the asphalt melter. One nozzle shall be directed at each end of the
asphalt melter. Each of these nozzles shall be directed downward at a 45-degree
angle from the vertical toward the respective end of the asphalt melter at the
junction between the dedrumming tunnel and the melting and storage tank. The
nozzle directional centerline of each of these nozzles shall lie in a vertical
plane perpendicular to the e.d of the tunnel and located midway between the
n
sides of the tunnel. Each of the eight nozzles shall be located at a distance
of 8 feet from the asphalt melter measured along the nozzle directional center-
line. Evidence of water leakage on the inside of the asphalt melter shall
constitute failure of this test.
4.5.2.5 Towing. Tow one empty asphalt melter in tune operating position over
dry, level ground at a speed of not less than 2 mph and in a figure eight pattern
laid out to contain a linear distance of not less than 2,000 feet. All addi-
tional piping and fittings (see 3.10) shall be carried in the storage cent-ainer
during this test. Evidence of weld failure or permanent deformation of or
damage to any part of the asphalt melter shall constitute failure of this test.
4.5.2.6 Lifting attachments.
4.5.2.6.1 Test procedure.
Lift the melter and hold it in suspension in its normal travel positon
a.
using slings that converge not more than 24 feet above the lowest
extremity of the melter. Determine the forward angles of application
for each provision. Measure the clearance between each sling and the
melter. Measure the eye openings and clearance dimensions of the
provisions.
Restrain the melter by anchoring the main frame and subject each
b.
attachment to a force-equal to the load factor specified in MIL-STD-209
times the load it carried in paragraph a above. An acceptable alternate
method of test shall be to lift the melter as in a above and add weights
to the melter until the required force is obtained. Hold the melter
under either of the above loading conditions for not less than 90
seconds.
4.5.2.6.2 Failure criteria. Weld failure, permanent deformation of the
melter or any slinging provision, slings converging more than 24 feet above the
lowest extremity of the melter, nonconformance to MIL-STD-209, or inability of
the dedrumming tunnel to be placed in the melting and storage tank utilizing
only those provisions provided for this purpose shall consitute failure of this
test.
