ISO 1209-1:2004

Rigid cellular plastics — Determination of flexural properties — Part 1: Basic bending test

ISO 1209-1:2004 specifies a simple method for assessing the behaviour of a bar of rigid cellular plastic under the action of three-point bending. It may be used to determine either the load for a specified deformation or the load at break. The version of the method specified uses small test specimens and does not produce pure bending. Hence it does not permit the calculation of the flexural strength or the apparent flexural modulus (modulus of elasticity). The user is referred to ISO 1209-2 for the determination of these parameters. The method is not applicable to cellular plastics in which significant crushing is observed. Numerical values should be compared only when determined on materials of similar physical properties and dimensions. The method is limited to materials of 20 mm thickness or greater.

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 1209-1 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 8).

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

This part of ISO 1209 specifies a simple method for assessing the behaviour of a bar of rigid cellular plastic

under the action of three-point bending.
It may be used to determine
— either the load for a specified deformation;
— or the load at break.

The version of the method specified in this part of ISO 1209 uses small test specimens and does not produce

pure bending. Hence it does not permit the calculation of the flexural strength or the apparent flexural modulus

(modulus of elasticity). The user is referred to ISO 1209-2 for the determination of these parameters.

The method is not applicable to cellular plastics in which significant crushing is observed. Numerical values
