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.
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 111, Round steel link chains, chain slings,
components and accessories, Subcommittee SC 3, Components and accessories.
This fourth edition cancels and replaces the third edition (ISO 2415:2004), which has been technically
revised.
The main changes are as follows:
— modification of the grades to 6, 8 and 10;
— corresponding adaption of preferred dimensions, heat treatment and mechanical requirements;
— selective method to ensure product material toughness; and
— including the guidance for safe use of shackles in Annex B.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

INTERNATIONAL STANDARD ISO 2415:2022(E)
Forged shackles for general lifting purposes — Dee
shackles and bow shackles
1 Scope
This document specifies the general characteristics of forged dee and bow shackles in a range of sizes
having working load limits from 0,5 t to 120 t and in grades 6, 8 and 10, and presents their performance
and preferred dimensions necessary for their interchangeability and compatibility with other
components for use in the temperature range of -20 °C to 200 °C.
