ASTM F1144-98(2007)

Standard Specification for Manhole Cover Assembly, Bolted, Semi-Flush, Oiltight and Watertight, Hinged

ABSTRACT
This specification covers the requirements for the design and construction of a semi-flush, oiltight, and watertight bolted hinged manhole cover assembly for use in deck or bulkheads subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressure. Not covered by this specification are the design requirements for manhole cover assembly subjected to primary or cyclic loads and certain hazardous cargos. The manhole cover assembly covered by this specification are classified into various types (Types I and II based on size of access opening), grades (Grades 1-3 based on the thickness of the cover plate), and classes (Classes A and B based on surface finish). The assembly shall be comprised of covers, mounting rings, gaskets, studs, washers, hinge assemblies, and nuts. The components shall be manufactured from carbon structural steel (plate for the cover, ring, hinge pad, and hinge blade), steel (round bar for hinge pin), ordinary steel (welded studs), and yellow brass (washers, heavy hex nuts, and cotter pin). The assembly shall be free of splinters, sharp edges, burrs, projections, and weld splatters, and shall have a Class A finish. Pressure and tightness tests shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification provides design and construction criteria for a semi-flush, oiltight and watertight bolted hinged manhole cover assembly.
1.2 The manhole cover assemblies depicted on this specification are for use in decks or bulkheads requiring oiltight and watertight covers that are not required to be completely flush. Manhole cover assemblies shall be complete with covers, mounting rings, gaskets, studs, washers, hinge assemblies, and nuts.
1.3 Handles, if required, shall be as specified in the ordering information.
1.4 Values stated in inch-pound units are to be regarded as standard.
1.5 This standard is not applicable to certain hazardous cargos. (See 46CFR 153.254 and 46CFR 154.340.)  
1.6 This specification provides design and construction for manhole cover assemblies subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressures. Where manhole cover assemblies are subjected to primary or cyclic loads, other reinforcement or construction criteria may be necessary to integrate the manhole assembly with the required structural reinforcement for openings in decks or bulkheads. Design of the manhole cover assembly for primary or cyclic loads is beyond the scope of this specification.
