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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received. www.iso.org/patents

Part 4:
Stopping, acceleration, traversing
1 Scope
This part of ISO 13643 defines symbols and terms and provides guidelines for the conduct of tests to
give evidence about the stopping, acceleration, and traversing of surface ships, submarines, and models.
It is intended to be read in conjunction with ISO 13643-1.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
acceleration test
manoeuvring test to determine the ship’s performance under positive acceleration or negative
acceleration (deceleration)
3.2
coasting stop test
manoeuvring test to determine the ship’s behaviour after the propulsion plant has been disengaged
and/or shut down
3.3

3.5
traversing test
manoeuvring test to determine the ship’s capability to execute a lateral movement, if possible without
turning and moving in the longitudinal direction
4 Test-related physical quantities
Test-related physical quantities are listed in Table 1. The more general quantities and concepts concerning
the manoeuvring of ships are set out in ISO 13643-1.
For quantities and their units, ISO 80000-1 and ISO 80000-3 shall be used.
