1、Designation: F1143 98 (Reapproved 2012) An American National StandardStandard Specification forManhole Cover Assembly, Bolted, Raised, Oiltight andWatertight1This standard is issued under the fixed designation F1143; the number immediately following the designation indicates the year oforiginal adop
2、tion or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification provides design and constructioncriteria for a raised
3、, bolted, oiltight, and watertight manholecover assembly.1.2 The manhole cover assemblies depicted in this specifi-cation are for use in decks or bulkheads in which the manholecover assemblies must be of the raised type. Manhole covershall be complete with coaming, gasket, welded studs or bolts,wash
4、ers, and nuts.1.3 Determination of the use of handles will be as specifiedin the ordering information.1.4 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.5 This specification is not applicable to certain hazardouscarg
5、os (see Section 46 CFR 153.254 and 46 CFR 154.340).1.6 This specification provides design and construction formanhole cover assemblies subjected to lateral pressures such asresulting from vehicle loads or hydrostatic pressures. Wheremanhole cover assemblies are subjected to primary or cyclicloads, o
6、ther reinforcement or construction criteria may benecessary to integrate the manhole assembly with the requiredstructural reinforcement for openings in decks or bulkheads.Design of the manhole cover assembly for primary or cyclicloads is beyond the scope of this specification.2.
