Plastics - Poly(methyl methacrylate) (PMMA) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 24026-2:2020)

1.1 This document specifies the methods of preparation of test specimens and the test methods to
be used in determining the properties of poly(methyl methacrylate) (PMMA) moulding and extrusion
materials. It gives the requirements for handling test material and for conditioning both the test material
before moulding and the specimens before testing.
1.2 This document specifies procedures and conditions for the preparation of test specimens and
procedures for measuring properties of the materials from which these specimens are made. It lists
properties and test methods which are suitable and necessary to characterize poly(methyl methacrylate)
moulding and extrusion materials.
1.3 The properties have been selected from the general test methods in ISO 10350-1. Other test
methods in wide use for, or of particular significance to, these moulding and extrusion materials are also
included in this document, as are the designatory properties specified in ISO 24026-1.

1.1    Le présent document spécifie les méthodes de préparation des éprouvettes et les méthodes d'essai qui doivent être utilisées pour la détermination des propriétés des matériaux pour moulage et extrusion à base de poly(méthacrylate de méthyle) (PMMA). Il donne les exigences relatives à la manipulation du matériau d'essai et au conditionnement du matériau d'essai avant moulage et des éprouvettes avant essai.
1.2    Le présent document spécifie les modes opératoires et les conditions nécessaires à la préparation des éprouvettes, ainsi que les modes opératoires de mesure des propriétés des matériaux à partir desquels les éprouvettes sont obtenues sont donnés. Il liste les propriétés et méthodes d'essai qui sont utiles et nécessaires pour caractériser les matériaux pour moulage et extrusion à base de poly(méthacrylate de méthyle).
1.3    Les propriétés ont été sélectionnées parmi les méthodes d'essai générales de l'ISO 10350-1. D'autres méthodes d'essai largement utilisées ou qui revêtent une importance particulière pour ces matériaux pour moulage et extrusion sont aussi incluses dans le présent document; c'est le cas des propriétés de désignation spécifiées dans l'ISO 24026‑1.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
