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, 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, 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 ).

This document was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 4, Outfitting and deck machinery.

This fourth edition cancels and replaces the third edition (ISO 1704:2008), which has been technically revised.

The main changes are as follows:

• grade 4 stud-link anchor chain with higher strength has been defined in Table 1 and mechanical properties have been specified in Clause 9;
• the terms and definitions of swivel shackles have been added in 3.8;
• tolerances on the nominal diameter of the links have been adjusted properly in Clause 5;
• the nominal dimensions of the enlarged link, end link, D type joining shackle and Kenter type joining shackle have been adjusted properly in Tables 3, 4, 5 and 6;
• the nominal diameters and shape of Type A and Type B swivel shackles have been added in 7.9 and 7.10;
• the sketch examples of connecting chain-shots with joining shackle and examples of connecting outboard chain-shot to anchor and chain end shot have been added in Figures 11 and 12;
• information on requirements for anchor chains, designation of size, material requirement, loading methods and marking has been added in Clauses 8, 9 10 and 11;
• incorrect dimensions in Table 3 of ISO 1704:2008 have been corrected.
