Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 5894 was prepared by Technical Committee ISO/TC 8, Ships and marine technology,
Subcommittee SC 8, Structures.
This second edition cancels and replaces the first edition (ISO 5894:1978).
The following amendments have been made to the first edition.
a) The nominal sizes 500 mm �400 mm and 600 mm � 450 mm for type A manholes are no longer specified.
b) Type B, type C and type D manholes are no longer specified.
c) The type A manhole has been renamed type O manhole (O for oval).
d) The nominal size 800 mm � 600 mm for type O has been added.
e) The type E manhole (E for elliptical) with nominal size 800 mm � 400 mm has been added.
f) For the nominal sizes 600 mm � 400 mm and 450 mm � 350 mm for type O, the sizes a and b (in the 1978
2 2
edition) are reduced by 20 mm. The position of fasteners is therefore changed.
g) The sizes for length and breadth of covers and coaming rings (L , L , b and b ) have been added.
2 3 2 3
h) The designation has been added.

INTERNATIONAL STANDARD ISO 5894:1999(E)
Ships and marine technology — Manholes with bolted covers
1 Scope
This International Standard specifies requirements for watertight and oiltight manholes of the current type with
bolted covers, for general shipboard use other than for pressure vessels.
It specifies the dimensions for the holes in the plating and the number, size and position of the fasteners. All forms
of manhole, whether of raised coaming, surface mounted or recessed cover types, shall conform to these principal
particulars.
The details of the manholes shall be the responsibility of the manufacturer.
NOTE Users of this International Standard should note that, while observing the requirements of the standard, they should
at the same time ensure compliance with such statutory requirements, rules and regulations as may be applicable to the
individual ship concerned.
