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.
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 8861 was prepared by Technical Committee
ISO/TC 8, Ships and marine technology, Subcommittee SC 3, Piping and
machinery.
This second edition cancels and replaces the first edition (ISO 8861:1988),
of which it constitutes a technical revision.
Annex A of this International Standard is for information only.

INTERNATIONAL STANDARD  ISO ISO 8861:1998(E)
Shipbuilding — Engine-room ventilation in diesel-engined
ships — Design requirements and basis of calculations
1  Scope
This International Standard specifies design requirements and suitable calculation methods for
the ventilation of the engine room in diesel-engined ships, for normal conditions in all waters.
Annex A provides guidance and good practice in the design of ventilation systems for ships'
engine rooms.
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.
2  Normative references

3.3 service standard power
declares that an engine is capable of delivering, using only the essential dependent auxiliaries,
between the normal maintenance intervals stated by the manufacturer and under the following
conditions:
a) at a stated speed at the ambient and operating conditions of the engine application;
b) with the declared power adjusted or corrected as determined by the manufacturer to the
stated ambient and operating conditions of the engine application;
c) with the maintenance prescribed by the engine manufacturer being carried out.
