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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT), see the following URL: Foreword — Supplementary information.

Introduction
This International standard specifies the testing procedure and the specimen shapes for cross-tension
testing of mechanical joints. Items to be reported after testing are the cross tension strength as well as
the fracture modes, which are given as drawings as the type of joint failure. The International Standard
also includes normative references, terms and definitions and an example for a test report.

INTERNATIONAL STANDARD ISO 16237:2015(E)
Mechanical joining — Destructive testing of joints —
Specimen dimensions and test procedure for cross-tension
testing of single joints
1 Scope
This International Standard specifies the geometry of the test specimens and the method for the cross-
tension testing of single mechanical joints on single-lap test specimens up to a single sheet thickness of
4,5 mm.
The term “sheet”, as used in this International Standard, includes extrusions and cast materials.
The purpose of the cross-tension test is to determine the mechanical characteristics and the failure
types of the joints made with different joining methods.
This International Standard does not apply to civil engineering applications such as metal building and
steel construction which are covered by other applicable standards.
2 Normative references
