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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 1922 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 10,
Cellular plastics.
This third edition cancels and replaces the second edition (ISO 1922:1981), which has been technically revised.
Annex A forms a normative part of this International Standard.

INTERNATIONAL STANDARD ISO 1922:2001(E)
Rigid cellular plastics — Determination of shear strength
1 Scope
This International Standard specifies a method of determining the shear strength of rigid cellular plastics. It also
provides for the optional determination of shear modulus.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
ISO 291:1997, Plastics — Standard atmospheres for conditioning and testing.
ISO 1923:1981, Cellular plastics and rubbers — Determination of linear dimensions.
3Principle
A shear stress is applied to a test specimen of defined shape by means of metal supports bonded to the specimen.
4 Apparatus
4.1 Test machine
The test machine (see Figure 1) shall be such that:
a) a test specimen having the form and dimensions specified in clause 5 is held vertically between two fixing
devices each comprising a metal support, one of these devices being fixed and the other movable, and the
stress being transmitted along the longitudinal axis of the specimen;
b) the movable grip will be moved away from the fixed grip at a constant rate of (1� 0,5) mm per minute in a
