24、2002+A1:2006 (E) 4 Introduction The manhole cover assembly, the subject of this standard, seals the manhole which gives access to the inside of the tank compartment for manufacturing, cleaning, and inspection, and forms an integral part of a loading, unloading or venting function. NOTE Cover plates
25、used to seal manholes are not the subject of this standard. The manhole cover assembly, which comprises the manhole cover and gaskets and may include devices to secure it to the tank shell neckring, may also provide the mounting points for equipment such as: fill hole cover; pressure limiting device
26、(s); level detection equipment; vapour transfer valve; pressure and vacuum breather vent.
