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 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
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 (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

DRAFT INTERNATIONAL STANDARD ISO/DIS 5540:2022(E)
Ships and marine technology — Sea-going vessels — Dual
traction/stowage winches for oceanographic research
1 Scope
This document specifies requirements for the design, construction, safety, performance and acceptance
testing of dual traction/stowage winches for oceanographic research (hereafter referred as to “dual
traction / stowage winches”), with hydraulic and electric drive.
Dual traction/stowage winches are mainly used for fixed-point and towing marine survey, involving
marine geological sampling, seawater water body parameter measurement and marine biological
survey.
This document is applicable to the design, manufacturing, and acceptance testing of dual traction/
stowage winch.
