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.
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.
International Standard ISO 9653 was prepared by Technical Committee
ISO/TC 61, Plastics, Subcommittee SC 11, Products.
This second edition cancels and replaces the first edition (ISO 9653:1991).
In addition to normative references, requirements have been added for the
preparation of plastic-to-plastic specimens prior to bonding (8.1.3), and the
requirements for specimen conditioning (9.1) and for the reporting of failure
patterns (10.4.3) changed.

Adhesives — Test method for shear impact strength of
adhesive bonds
1  Scope
1.1  This International Standard specifies a method for the determination of the comparative impact value of
adhesive bonds in shear, when tested on standard specimens, and using specified conditions of preparation,
conditioning and testing.
1.2  The method is intended to be used for wood-to-wood or metal-to-metal bonds, but may be extended to cover
plastics-to-plastics bonds as well as bonds between combinations of these materials.
2  Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.

3  Definition
For the purposes of this International Standard, the following definition applies.
3.1  impact value: Energy absorbed by a specimen of standard design when sheared by a single blow of a
testing-machine hammer. The impact value is expressed in joules per square metre.
4  Principle
The impact value is determined by using a pendulum-type impact machine on a metal-to-metal or wood-to-wood
specimen.

5  Apparatus
with a impact-head velocity of 3,4 m/s, comprising the elements specified in
5.1 Pendulum-type impact machine,
5.1.1 to 5.1.3.
5.1.1  Impact head, with a flat striking face slightly wider than the specimen and aligned to strike the specimen full-
face.
5.1.2  Specimen-holding fixture, as shown in figure 1. The fixture illustrated is not always suitable for use with all
impact machines and vices. Dimensions and design of the fixture may be varied as required for adaptation to
machines and vices available, provided the following general requirements are met:
The fixture shall be machined from a solid piece of steel and solidly bolted to the base of the testing machine.
Corners shall be drilled to ensure that the specimen sets flush against the retaining end of the fixture. The drilled
corners are provided to minimize dirt collection at the corners which could hold the end of the specimen away from
the face of the fixture. The fixture shall be provided with a screw to tighten the specimen in the fixture to minimize
the tendency of the specimen to overturn when struck. A metal plate may be placed between the end of the block
and the end of the screw when non-metallic adherends are used. The fixture shall be so located that the specimen
will be struck at the point of maximum head velocity.

5.1.3  Vice or bolts, to hold the fixture firm and immobile under the stress of the testing-machine hammer. The total
height of the vice fixture and specimen shall be such that the lower edge of the striking face of the impact head
strikes the specimen as near the adhesive line as possible, preferably within 0,80 mm. Ordinarily, the distance
between the top of the jaws of the vice of the machine and the bottom of the striking face of the head is 22 mm. The
proper height of the specimen may be obtained by adjusting its height in the fixture.
NOTE —  Additional information on impact-testing machines and their calibration may be found in ISO 178:1993, Plastics —
Determination of flexural properties, and ISO 179 (both parts), Plastics — Determination of Charpy impact properties.
5.2  Conditioning chamber, capable of maintaining a relative humidity of (50 – 5) % at 23 °C – 2 °C.
NOTE —  A saturated solution of calcium nitrate will give approximately 51 % relative humidity at the test temperature.
6  Specimens
6.1  The specimen for metal-to-metal adhesives shall conform to the dimensions given in figure 2a) whenever
possible. In cases wh
