Standard Specification for Manhole Cover Assembly, Bolted, Raised, Oiltight and Watertight

SCOPE
1.1 This specification provides design and construction criteria for a raised, bolted, oiltight, and watertight manhole cover assembly.
1.2 The manhole cover assemblies depicted in this specification are for use in decks or bulkheads in which the manhole cover assemblies must be of the raised type. Manhole cover shall be complete with coaming, gasket, welded studs or bolts, washers, and nuts.
1.3 Determination of the use of handles will be as specified in the ordering information.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This specification is not applicable to certain hazardous cargos (see Section 46 CFR 153.254 and 46 CFR 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.
