Plastics - Methods for determining the density of non-cellular plastics - Part 2: Density gradient column method (ISO 1183-2:2019)

This document specifies a gradient column method for the determination of the density of non-cellular moulded or extruded plastics or pellets in void-free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom.
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. The density of plastic materials can 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.

Kunststoffe - Verfahren zur Bestimmung der Dichte von nicht verschäumten Kunststoffen - Teil 2: Verfahren mit Dichtegradientensäule (ISO 1183-2:2019)

Dieses Dokument legt ein Verfahren mit Dichtegradientensäule zur Bestimmung der Dichte von nicht verschäumten, blasenfreien geformten oder extrudierten Kunststoffen oder Pellets fest. Dichtegradienten-säulen sind Säulen, die ein Gemisch von zwei Flüssigkeiten enthalten und in denen die Dichte gleichmäßig vom oberen Teil der Säule zum Boden zunimmt.
ANMERKUNG   Die Dichte wird häufig verwendet, um die Veränderungen in der physikalischen Struktur oder Zusammensetzung von Kunststoffmaterialien zu verfolgen. Die Dichte kann auch bei der Beurteilung der Einheitlichkeit von Proben oder Probekörpern von Nutzen sein. Die Dichte von Kunststoffen kann von der Wahl des Verfahrens zur Herstellung der Probekörper abhängig sein. Ist dies der Fall, sollen genaue Einzelheiten zum Herstellungsverfahren der Probekörper in die entsprechende Werkstoffspezifikation aufgenommen werden.

Plastiques - Méthodes de détermination de la masse volumique des plastiques non alvéolaires - Partie 2: Méthode de la colonne à gradient de masse volumique (ISO 1183-2:2019)

Le présent document spécifie une méthode qui utilise une colonne à gradient pour déterminer la masse volumique des plastiques non alvéolaires, moulés ou extrudés, ou de granulés exempts de cavités fermées. Les colonnes à gradient de masse volumique contiennent un mélange de deux liquides, dont la masse volumique augmente uniformément du haut de la colonne vers le bas.
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 peut dépendre 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.

Polimerni materiali - Metode za določanje gostote nepenjenih polimernih materialov - 2. del: Kolonska metoda na osnovi gradienta gostote (ISO 1183-2:2019)

Ta dokument določa kolonsko metodo na osnovi gradienta za določanje gostote nepenjenih ulitih ali ekstrudiranih polimernih materialov ali peletov brez praznine. Stolpci gradientov gostote so stolpci, ki vsebujejo mešanico dveh tekočin, pri čemer se gostota v stolpcu enakomerno povečuje od vrha proti dnu.
OPOMBA: Gostota se pogosto uporablja za spremljanje odstopanj v fizični strukturi ali sestavi plastičnih
materialov. Gostota je lahko uporabna tudi pri ocenjevanju enakomernosti vzorcev ali primerkov. Gostota plastičnih materialov je lahko odvisna od izbire metode priprave primerka. V tem primeru je treba v specifikacijo ustreznega materiala vključiti natančne podrobnosti o metodi priprave primerkov.

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).
