Plastics - Methods for determining the density of non-cellular plastics - Part 1: Immersion method, liquid pycnometer method and titration method (ISO 1183-1:2025)

This document specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules.
—     Method A: Immersion method, for solid plastics (except for powders) in void-free form.
—     Method B: Liquid pycnometer method, for particles, powders, flakes, granules or small pieces of finished parts.
—     Method C: Titration method, for plastics in any void-free form.
NOTE            Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. Often, the density of plastic materials depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification. This note is applicable to all three methods.
Annex C provides further information for calculating the volume of the specimen used for the determination of the density in the case that method A (the immersion method) is applied.

Kunststoffe - Verfahren zur Bestimmung der Dichte von nicht verschäumten Kunststoffen - Teil 1: Eintauchverfahren, Verfahren mit Flüssigkeitspyknometer und Titrationsverfahren (ISO 1183-1:2025)

Dieses Dokument legt drei Verfahren zur Bestimmung der Dichte von nicht verschäumten Kunststoffen fest, die in Form von blasenfreien geformten oder extrudierten Gegenständen oder auch als Pulver, Flocken oder Granulat vorliegen.
   Verfahren A: Eintauchverfahren, für blasenfreie feste Kunststoffe (ausgenommen Pulver);
   Verfahren B: Verfahren mit Flüssigkeitspyknometer, für Teilchen, Pulver, Flocken, Granulat oder zerkleinerte Fertigteile;
   Verfahren C: Titrationsverfahren, für Kunststoffe in jeder blasenfreien Form.
ANMERKUNG   Die Dichte wird häufig verwendet, um die Veränderungen in der physikalischen Struktur oder Zusammensetzung von Kunststoffen zu verfolgen. Die Dichte kann auch bei der Beurteilung der Einheitlichkeit von Proben oder Probekörpern von Nutzen sein. Häufig hängt die Dichte von Kunststoffen von der Wahl des Verfahrens zur Herstellung der Probekörper ab. Ist dies der Fall, sollen genaue Einzelheiten zum Herstellungsverfahren der Probekörper in die entsprechende Werkstoffspezifikation aufgenommen werden. Diese Anmerkung gilt für alle drei Verfahren.
Anhang C enthält weitere Informationen zur Berechnung des Volumens von Probekörpern, die zur Bestimmung der Dichte nach Verfahren A (Eintauchverfahren) verwendet wurden.
WARNUNG — Die Anwendung dieses Dokuments kann die Anwendung gefährlicher Substanzen, Arbeitsgänge und Geräte einschließen. Dieses Dokument erhebt nicht den Anspruch, dass alle mit seiner Anwendung verbundenen Sicherheitsprobleme, soweit diese gegeben sind, angesprochen werden. Es liegt in der Verantwortung des Anwenders dieses Dokuments, vor dessen Anwendung geeignete Vorsichtsmaßnahmen für den Arbeits- und Gesundheitsschutz zu treffen.

Plastiques - Méthodes de détermination de la masse volumique des plastiques non alvéolaires - Partie 1: Méthode par immersion, méthode du pycnomètre en milieu liquide et méthode par titrage (ISO 1183-1:2025)

Le présent document spécifie trois méthodes de détermination de la masse volumique des plastiques non alvéolaires sous forme d’objets moulés ou extrudés exempts de cavités fermées, ainsi que de poudres, de paillettes ou de grains.
—     Méthode A: méthode par immersion, pour les plastiques solides exempts de cavités fermées (excepté les poudres).
—     Méthode B: méthode du pycnomètre en milieu liquide, pour les particules telles que les poudres, les paillettes, les grains ou les parties finies réduites en petits morceaux.
—     Méthode C: méthode par titrage, pour les plastiques exempts de cavités fermées.
NOTE            La masse volumique est fréquemment utilisée pour suivre les variations de la structure physique ou de la composition des matériaux plastiques. La masse volumique peut également se révéler utile pour évaluer l’uniformité des échantillons ou des éprouvettes. La masse volumique des matériaux plastiques dépend souvent du choix de la méthode de préparation de l’échantillon. Lorsque cela est applicable, des détails précis de la méthode de préparation de l’échantillon doivent être donnés dans les spécifications appropriées relatives à la matière. Cette note s’applique à chacune des trois méthodes.
L'Annexe C fournit des informations complémentaires pour le calcul du volume de l'échantillon utilisé pour la détermination de la masse volumique dans le cas où la méthode A (méthode par immersion) est appliquée.

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.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
