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 1209-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 10, Cellular plastics.
This second edition cancels and replaces the first edition (ISO 1209-1:1990), of which it constitutes a minor
revision intended principally to include precision data (see Clause 9).
ISO 1209 consists of the following parts, under the general title Rigid cellular plastics — Determination of
flexural properties:
— Part 1: Basic bending test
— Part 2: Determination of flexural strength and apparent flexural modulus of elasticity

INTERNATIONAL STANDARD ISO 1209-2:2004(E)
Rigid cellular plastics — Determination of flexural properties —
Part 2:
Determination of flexural strength and apparent flexural
modulus of elasticity
1Scope
This part of ISO 1209 specifies a method for determining the flexural strength and the apparent flexural
modulus of elasticity of rigid cellular plastics.
2 Normative references
The following referenced documents are indispensable for the application 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 1923, Cellular plastics and rubbers — Determination of linear dimensions
3 Principle
A load is applied at a uniform rate by means of a loading edge to a test specimen supported at two positions.
The load is applied perpendicularly to the specimen at a position midway between the supporting positions (see
Figure 1). The load/deformation curve is recorded. From the curve, the flexural strength and the apparent
flexural modulus of elasticity are calculated.
4 Apparatus
4.1 Test machine, consisting of a universal mechanical-testing machine capable of operating at a constant
rate of movement of the moveable head.
The range of the test machine shall be such that the applied load can be measured with an accuracy of ±1%.
