This specification provides the design and construction criteria for bolted oiltight and watertight manhole cover assemblies that are subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressures, and used in decks or bulkheads in which the assembly must be of the raised type. Manhole covers shall be complete with coaming, gasket, welded studs or bolts, washers, and nuts. This specification does not address certain hazardous cargos, as well as the design of the manhole cover assembly for primary or cyclic loads.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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.
1.6 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.
