2、original 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 constructioncriteri
3、a for a semi-flush, oiltight and watertight bolted hingedmanhole cover assembly.1.2 The manhole cover assemblies depicted on this specifi-cation are for use in decks or bulkheads requiring oiltight andwatertight covers that are not required to be completely flush.Manhole cover assemblies shall be co
4、mplete with covers,mounting rings, gaskets, studs, washers, hinge assemblies, andnuts.1.3 Handles, if required, shall be as specified in the orderinginformation.1.4 Values stated in inch-pound units are to be regarded asstandard.1.5 This standard is not applicable to certain hazardouscargos. (See 46
5、CFR 153.254 and 46CFR 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, other reinforcement o
6、r 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.
