2、 adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification provides design and constructioncriteria for a
3、semi-flush, oiltight, and watertight bolted manholecover assembly.1.2 The manhole cover assembly depicted in this specifica-tion is for use in decks or bulkheads requiring oiltight andwatertight covers that are not required to be completely flush.Manhole cover assemblies shall be complete with cover
4、s,mounting rings, gaskets, welded studs, washers, and nuts.1.3 Handles, if required, shall be as specified in the orderinginformation.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 app
5、licable to certain hazardouscargos (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 subjec
