provided the paver produced meets all other requirements of this specification.
Used, rebuilt or remanufactured components, pieces and parts shall not be
incorporated in the paver.
3.5.1 Safety. All rotating or reciprocating parts and other parts subject to
high operational temperatures that are of such a nature or are so located as to
be a hazard to operating personnel, shall be guarded or insulated to the extent
necessary to eliminate the hazard. All walking surfaces shall be provided with
an anti-skid surface. Operator visibility shall be adequate to permit safe
operation in forward and reverse travel. All platforms, steps, and handholds
shall permit unhampered and nonhazardous entrance and exit from the paver. All
exhausts shall be directed so as not to endanger personnel or obstruct the view
of the operator. Fuel tanks shall be located in a manner which will not allow
spills and overflows to run on to the engine, exhaust or electrical equipment.
Electrical equipment shall be insulated, fully enclosed, or guarded. Nonfunc-
tional sharp edges, projecting points and protruding length of more than two
full threads of fastening devices shall be avoided.
3.6 Human factors engineering. The paver shall conform to Human Factors
Engineering Design Criteria as specified in MIL-STD-1472. Special design
emphasis shall be given, but not limited to 4 (General requirements), 5.1
(Control/Display Integration), 5.2 (Visual displays), 5.4 (Controls), 5.5
(Labeling), 5.6 (Anthropometry), 5.9 (Design for Maintainability), 5.12
(Operational and Maintenance Ground/Shipboard Vehicles), 5.13 (Hazards and
Safety) of MIL-STD-1472, as applicable.
3.7 Noise limits. The noise produced by the paver shall conform with
MIL-STD-1474 requirements when tested in accordance with 188.8.131.52. The
provisions of MIL-STD-1474, 4.3 and 4.4 shall be provided if and only if
MIL-STD-1474, 184.108.40.206 procedures have been pursued and documented to the
satisfaction of the procuring activity and written permission to exceed the 85
dB(A) limit is obtained from the procuring activity (see 6.2). Hazard signs
shall conform with MIL-STD-1474, 4.3 and be readable at the distance indicated
on the sign.
3.8 Maintainability. Design for maintainability shall be in accordance with
3.6. All major assemblies and installed attachments shall be accessible for
maintenance, repair, and replacement with minimum removal of other
major assemblies and installed attachments. Covers or plates which must be
removed for component adjustment, or daily maintenance, shall be equipped with
quick-disconnect fastenings. Drain outlets shall be accessible and provide for
drainage directly into a receptacle. Ease of maintenance provisions shall
incorporate features insuring operating clearances for handtools and lubricating
equipment, and the accessibility for service operations such as adding oil to
the engine crankcase and adding oil to gear cases. Each maintenance, assembly,
or disassembly operation required during testing in accordance with 4.4 shall be
accomplished by no more than two men (except a hoist and operator may be used as
necessary) using special tools furnished with the paver and common tools. After
completion of any maintenance operation, the paver shall operate as specified
