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 of the voluntary nature of standards, 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 www .iso

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11,
Products.
This third edition cancels and replaces the second edition (ISO 11003-1:2001), which has been
technically revised. The main changes compared to the previous edition are as follows:
— correction of the formula for angular displacement in 7.2;
— updated references.
A list of all parts in the ISO 11003 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 11003-1:2019(E)
Adhesives — Determination of shear behaviour of
structural adhesives —
Part 1:
Torsion test method using butt-bonded hollow cylinders
1 Scope
This document specifies a shear test for the characterization of adhesives in a bond. The shear stress/
strain properties of the adhesive (including the shear modulus) are useful for advanced design work,
such as in finite element analysis methods.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 291, Plastics — Standard atmospheres for conditioning and testing
ISO 10365, Adhesives — Designation of main failure patterns
ISO 17212, Structural adhesives — Guidelines for the surface preparation of metals and plastics prior to
adhesive bonding
3 Terms and definitions

4 Principle
The shear deformation of the adhesive in an annular bond between two hollow cylinders, and the
corresponding torque, are measured and recorded up to failure of the joint.
5 Apparatus
5.1 Torsion-testing machine, with a capacity of at least 300 N·m and preferably of 1 000 N·m.
Alternatively, a suitably adapted tensile-testing machine may be used. The machine shall include
equipment for recording the torque instantaneously with an error of less than 1 %. The gripping heads
shall be accurately aligned and, if no hydraulic gripping mechanism is available, all bolts and holes
shall be precisely machined so that the specimens are mounted in
