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.
Attention is drawn to the possibility that some of the elements of this part of ISO 3715 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 3715-2 was prepared by Technical Committee ISO/TC 8, Ships and marine technology,
Subcommittee SC 3, Piping and machinery.
ISO 3715 consists of the following parts, under the general title Ships and marine technology — Propulsion plants
for ships:
� Part 1: Vocabulary for geometry of propellers
� Part 2: Vocabulary for controllable-pitch propeller plants

Part 2:
Vocabulary for controllable-pitch propeller plants
Scope
This part of ISO 3715 gives terms and definitions applicable exclusively to continuously variable and hydraulic
operated controllable-pitch propeller units. It does not cover controllable-pitch propeller units for which only a few
specified pitch settings apply.
General vocabulary for the geometry of screw propellers is given in ISO 3715-1 and is also valid for controllable-
pitch propellers.
Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this part of ISO 3715. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 3715 are encouraged to investigate the
possibility of applying the most recent edition of the normative document indicated below. For undated references,
the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of
currently valid International Standards.
