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 19212 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.

Adhesives — Determination of temperature dependence of
shear strength
SAFETY STATEMENT — Persons using this document should be familiar with normal laboratory
practice, if applicable. 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 ensure compliance with any regulatory requirements.
1Scope
This International Standard specifies methods for determining the temperature dependence of the shear
strength of the adhesive or adhesive bond in adhesively bonded products.

4 Methods of test for shear strength
4.1 Test method for metals
For adherends made of metal, the shear strength shall be determined in accordance with ISO 4587.
4.2 Test method for wood
For adherends made of wood, the shear strength shall be determined in accordance with ISO 6238.
5 Test atmosphere
The specimens shall be conditioned and tested in one of the standard atmospheres specified in ISO 291.
6 Sampling and handling of adhesives
The method used for sampling and for handling the adhesives shall be in accordance with ISO 15605.
7 Kinds of adhesive and surface preparation of adherends
See ISO 17212.
8 Preparation of test specimens
8.1 Metal adherends
The test joints may be prepared either individually or from adhesively bonded panels, in each case following the
procedure specified in ISO 4587. Surface treatment of the adherends and application and curing of the
adhesive shall be in accordance with the adhesive manufacturer's instructions.
Whether prepared individually or cut from adhesively bonded panels, the shape and dimensions of the
specimens shall be as specified in ISO 4587.
For each test temperature (see Clause 9), the number of specimens tested shall be at least five.
8.2 Wood adherends
The test joints may be prepared either individually or from adhesively bonded blocks, in each case following the
procedure specified in ISO 6238. Surface treatment of the adherends and application and c
