Harte Schaumstoffe - Bestimmung des Volumenanteils offener und geschlossener Zellen (ISO 4590:2016)
Diese Internationale Norm legt ein allgemeines Verfahren zur Bestimmung des Volumenanteils offener und geschlossener Zellen von harten Schaumstoffen durch Messung des geometrischen Volumens und anschließender Messung des gasdichten Volumens der Probekörper fest.
Dieses Verfahren schließt eine Korrektur des scheinbaren Volumens offener Zellen ein, indem die durch Anschneiden bei der Herstellung der Probekörper geöffneten Zellen berücksichtigt werden. Für die Messung des gasdichten Volumens werden drei alternative Verfahren (Verfahren 1, Verfahren 2a und Verfahren 2b) sowie die entsprechende Prüfeinrichtung festgelegt.
Plastiques alvéolaires rigides - Détermination du pourcentage volumique de cellules ouvertes et de cellules fermées (ISO 4590:2016)
L'ISO 4590 :2016 spécifie un mode opératoire général permettant de déterminer le pourcentage volumique des cellules ouvertes et fermées de plastiques alvéolaires rigides par mesurage, en premier lieu, du volume géométrique d'éprouvettes de ces plastiques, puis du volume impénétrable à l'air de ces éprouvettes.
Le mode opératoire permet d'effectuer une correction du volume apparent des cellules ouvertes en tenant compte des cellules de surface ouvertes par la découpe des éprouvettes. Trois méthodes alternatives (méthode 1, méthode 2a et méthode 2b) et les appareillages correspondants sont spécifiés pour le mesurage du volume impénétrable.
Trdi penjeni polimerni materiali - Določanje prostorninskega deleža odprtih in zaprtih celic (ISO 4590:2016)
Ta mednarodni standard določa splošni postopek za določanje prostorninskega deleža
odprtih in zaprtih celic v trdih penjenih polimernih materialih na podlagi merjenja najprej geometrijske prostornine in nato še zračno neprepustne prostornine preskušancev.
Postopek vključuje popravek navidezne prostornine odprtih celic ob upoštevanju površinskih celic, odprtih pri rezanju med pripravo preskušanca. Za merjenje neprepustne prostornine so določene tri alternativne metode (1, 2a in 2b) ter ustrezna naprava.

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
on the ISO list of patent declarations received (see www.iso.org/patents).
