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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 4587 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.
This third edition cancels and replaces the second edition (ISO 4587:1995), which has been technically
revised.

INTERNATIONAL STANDARD ISO 4587:2003(E)

Adhesives — Determination of tensile lap-shear strength of
rigid-to-rigid bonded assemblies
1 Scope
This International Standard specifies a method for determining the tensile lap-shear strength of rigid-to-rigid
bonded assemblies using a standard specimen under specified conditions of preparation and testing. This test
procedure does not provide design information.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced

adhesive bonding
3 Principle
Adhesive lap-shear bond strength is determined by stressing a single-overlap joint between rigid adherends in
shear by the application of a tensile force parallel to the bond area and to the major axis of the specimen.
NOTE 1 Single-lap specimens are economical, practical and easy to make. They are the most widely used specimens
for development, evaluation and comparative studies involving adhesives and bonded products, including manufacturing
quality control.
NOTE 2 The strength values obtained from the single-lap specime
