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 10, Technical product documentation,
Subcommittee SC 6, Mechanical engineering documentation.
This second edition cancels and replaces the first edition (ISO 6413:1988), which has been technically
revised. The following changes have been made:
— title changed from Technical drawings — Representation of splines and serrations to Technical product
documentation — Representation of splines and serrations;
— Introduction added;
— normative references reviewed;
— figures improved and titles added.
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.

Introduction
The representations of splines in technical product documentation are different from those used in
mechanical drawings. In mechanical drawings, the drawings of spline teeth are complicated.
This document improves the efficiency of drawing.
INTERNATIONAL STANDARD ISO 6413:2018(E)
Technical product documentation — Representation of
splines and serrations
1 Scope
This document specifies the rules and graphical symbols for the representations of splines and
serrations in technical product documentation.
Two methods of representation are specified:
a) complete representation;
b) simplified representation.
The rules and graphical symbols specified in this document are applicable to detail drawings of parts
(shafts and hubs) and to assembly drawings of joints.
NOTE For uniformity, all the figures in this document have been drawn in the first-angle orthographic
projection. A third-angle orthographic projection could equally have been used without prejudice to principles
established.
