ASTM F 1143 Document Information:
Title
Standard Specification for Manhole Cover Assembly, Bolted, Raised, Oiltight and Watertight
ASTM International
Publication Date:
Aug 10, 1998
Scope:
This specification provides design and construction criteria for
a raised, bolted, oiltight, and watertight manhole cover
assembly.
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.
Determination of the use of handles will be as specified in the
ordering information.
The values stated in inch-pound units are to be regarded as the
standard. The values given in parentheses are for information
only.
This specification is not applicable to certain hazardous cargos
(see Section 46 CFR 153.254 and 46 CFR 154.340).
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.
