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.

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

This document was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 5,
Quality analysis and assurance.
This second edition cancels and replaces the first edition (ISO 3547-5:2007), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Clause 2 has been updated;
— Clause 9 has been updated;
— Figure 8 has been updated.

Introduction
Wrapped bushes in the free condition are flexible, but after insertion they adapt largely to the shape of
the housing bore due to the oversize between the outside diameter of the bush and the housing bore.
For this reason, checking of the outside diameter of wrapped bushes can only be carried out under a
constraining load by use of specialized measuring equipment.

Part 5:
Checking the outside diameter
1 Scope
This document specifies, following ISO 12301, the checking of the outside diameter of wrapped bushes
(ISO 3547-2:2017, methods A, B and D) and describes the necessary checking methods and measuring
equipment.
NOTE The dimensions and tolerances of wrapped bushes are given in ISO 3547-1. Checking the wall thickness
is the subject of ISO 3547-7.
2 Normative references
