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 www .iso

This third edition cancels and replaces the second edition (ISO 4386-2:2012), of which it constitutes a
minor revision. The changes compared to the previous edition are as follows:

Introduction
Long years of experience with bond tests led to an adaptation of this document. The test apparatus has
been modified to reduce the negative local bending stress influence on the specimen. The geometry
of the test specimen has been modified to avoid negative influence due to tolerances. A description of
the specimen machining sequence has been added to get a more uniform specimen. A subclause on the
application for quality control has been added.

Part 2:
Destructive testing of bond for bearing metal layer
thicknesses greater than or equal to 2 mm
1 Scope
This document specifies a tensile test method for determination of the bond strength between the
bearing metal and the backing. The test can be applied to multilayer plain bearings with bearing metals
based on lead, tin, copper or aluminium. For tested layer thicknesses ≥ 2 mm, a raw lining thickness of a
minimum additional 1 mm is necessary.
The backings are from steel, cast steel or copper alloys. The bond strength test does not apply to
bearings with cast iron backing.
The test applies to all thrust bearings and to journal bearings with an inner diameter of backing ≥ 90 mm.
The test can be used for comparative investigations into the influence on the bond strength of various
processes and types of material. In addi
