This specification provides the design and construction criteria for a semi-flush 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 requiring manhole covers that are not required to be completely flush. Manhole cover assemblies shall be complete with covers, mounting rings, gaskets, welded studs, 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.
1.1 This specification provides design and construction criteria for a semi-flush, oiltight, and watertight bolted manhole cover assembly.
1.2 The manhole cover assembly depicted in this specification is 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, welded studs, washers, and nuts.
1.3 Handles, if required, shall 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.
