MIL-C-0052980C(ME)
2 inches larger in diameter than the rubber feet, whichever is
larger.
The compressor shall be held to the floor by gravity alone,
and movement shall in no way be restricted by mechanical
attachments, braces, wheel chocks, or other means integral to the
Location of either or both of the rubber feet, wholly
compressor.
or in part, outside of or upon the circles at any time during the
8-hour period of operation shall constitute failure of this test.
4.5.2.12.2
Mobility.
After completion of the 500-hour endurance
test, conduct a test for mobility as follows:
a.
Elevate the handle to a height of not less than 30 inches
nor more than 48 inches and move the compressor not less
than 100 yards turning in complete circles to the right
and left during the movement.
At least 50 yards of the
movement shall be in a straight line.
Cart the compressor
over a 12-inch drop onto a concrete surface not less than
three times.
b.
Tilt the compressor to an angle of not less than
45 degrees by elevating one side of the frame and allowing
the wheel and landing leg on the opposite side of the
frame to rest on a concrete floor.
Allow the elevated
side to fall to a position of rest on the concrete floor
without any restraining forces being applied.
Do this not
less than two times for each side.
c.
Inability to be moved by one man, inability to be carted
in a straight path, inability to be turned either to the
right or the left, or fracture or permanent deformation of
any component or part or leakage of gasoline from the tank
shall constitute failure of this test.
4.5.2.12.3 Tilted operation.
Tilt the compressor 15 degrees from
the horizontal about the longitudinal axis and operate in this
position for 30 minutes.
This test shall be performed in each of
the four directions (compressor tilted with respect to longitudinal
and transverse axes) .
Allow the compressor to stand for 4 hours in
the tilted position most likely to adversely affect the lubrication
or fuel system, then start and operate the compressor for 30
minutes.
Any malfunction due to tilted operation, permanent
deformation of any part of component, or leakage of gasoline from
the tank shall constitute failure of this test.
4.5.2.13
class 3.
4.5.2.13.1 Casters.
Push and pull the compressor horizontally in
all directions, turn the compressor 360 degrees, and tilt the
compressor in 15 degrees from the horizontal in all directions.
Overturning or any condition that interferes with the
maneuverability of the compressor or physical damage to the
compressor shall constitute failure of this test.
4.5.2.14
Exhaust and fuel system.
