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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and 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 www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee
SC 4, Outfitting and deck machinery.
This third edition cancels and replaces the second edition (ISO 6325:1987), which has been technically
revised.
The main changes are as follows:
— in Figure 3, a combined track and roller stopper with adjust block has been added;
— in 4.2, the nominal size of the cable stopper corresponding to the nominal size of anchor chain has been
added according to ISO 1704;
— in 5.1, designed environmental conditions and material requirements have been added;
— in 5.7, location design requirements of cable stopper have been added;
— in Clause 6, functional, operational and installation requirements have been added;
— in Clause 7, acceptance tests requirements have been added;
— Annex A and Annex B have been deleted.
Any feedback or questions on this document should be directed to the user’s national standards body. A

3.1
cable stopper
device which is secured to the ship’s structure, separate from the cable lifter, for the purpose of securing a
chain cable against the tension from the anchor
Note 1 to entry: The stopper also serves as a guide for the chain cable during operation.
3.2
class A cable stopper
cable stopper (3.1) designed and constructed to withstand, without permanent deformation, 80 % of the
nominal breaking load of the maximum diameter and the highest chain cable grade for which it is intended
3.3
class B cable stopper
cable stopper (3.1) designed and constructed to withstand, without permanent deformation, 40 % of the
nominal breaking load of the maximum diameter and the highest chain cable grade for which it is intended
3.4
right-hand cable stopper
cable stopper (3.1) which is operated from the right-hand side when seen from the cable lifter
Note 1 to entry: The right-hand cable stopper is shown in Figure 1.
3.5
left-hand cable stopper
cable stopper (3.1) which is operated from the left-hand side when seen from the cable lifter
