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 on 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 the following URL: www . i so .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 3,
Dimensions, tolerances and construction details.
This third edition cancels and replaces the second edition (ISO 3547-2:2006), which has been technically
revised.

Plain bearings — Wrapped bushes —
Part 2:
Test data for outside and inside diameters
1 Scope
This document specifies the test data for outside and inside diameters of wrapped bushes made of
mono and multi-layer bearing material for plain bearing applications. It also specifies test designations.
Since the wall thickness of the bush is measured in the free condition, no special test data are required
for this on the drawing (see ISO 3547-5 and ISO 3547-6).
NOTE Depending on the manufacturing method, the back of the bushes can show isolated light depressions
and, similarly, bushes with lubrication holes, grooves and bore indentations can show distortion. It is therefore
suggested to measure the wall thickness away from these areas.
