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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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 45, Rubber and rubber products, Subcommittee
SC 2, Testing and analysis.
This sixth edition cancels and replaces the fifth edition (ISO 5600:2017), which has been technically revised.
The main changes are as follows:
— the normative references have been updated in Clause 2, Clause 5 and Table A.1;
— the class of tensile-testing machine has been upgraded from class 2 to class 1 in Clause 5;
— the expression of the type of adhesion failure has been changed in 9.2.

Rubber — Determination of adhesion to rigid materials using
conical shaped parts
WARNING 1 — Persons using this document should be familiar with normal laboratory practice. This
document does not purport to address all of the safety problems, if any, associated with its use. It is
the responsibility of the user to establish appropriate safety and health practices and to determine
the applicability of any other restrictions.
WARNING 2 — Certain procedures specified in this document can involve the use or generation of
substances, or the generation of waste, that could constitute a local environmental hazard. Reference
should be made to appropriate documentation on safe handling and disposal after use.
1 Scope
This document specifies a method for the determination of the static vulcanized adhesion strength of rubber
compounds to rigid materials. The test piece is composed of two conical ends of the rigid material, joined by
a cylinder of rubber.
The adhesion is obtained by a bonding system which can include not only the rigid material and the rubber
compound, but other elements such as thin alloy coatings or chemical treatments of rigid parts and either a
single cement or both primer and cover cements. The bonding system for preparing the test pieces should
be adequately specified by the user, but a provision is made in this document for the evaluation of different
types of failure related to a complex bonding system.
The method is designed primarily for test pieces prepared in the laboratory under standard conditions
in order to provide data for development and control of bonding systems and their components, such as
cements or special rubber compounds, and of methods of manufacture. While intended to be applied where
the rubber is bonded to rigid supporting pieces, it can be inapplicable such cases where the support, although
of high-modulus material, has a low rigidity due to small transverse dimensions, as in the case of rubber
bonded to metal wires, cords or thin sheets.
